99-675: The most direct ancestor to SKOS was the RDF Thesaurus work undertaken in the second phase of the EU DESIRE project . Motivated by the need to improve the user interface and usability of multi-service browsing and searching, a basic RDF vocabulary for Thesauri was produced. As noted later in the SWAD-Europe workplan, the DESIRE work was adopted and further developed in the SOSIG and LIMBER projects. A version of

198-477: A Common European Home . The 1960s saw the first attempts at enlargement . In 1961, Denmark , Ireland , the United Kingdom and Norway (in 1962), applied to join the three Communities. However, President Charles de Gaulle saw British membership as a Trojan Horse for U.S. influence and vetoed membership, and the applications of all four countries were suspended. Greece became the first country to join

297-508: A Parliamentary Assembly and Courts . Collectively they were known as the European Communities . The Communities still had independent personalities although were increasingly integrated. Future treaties granted the community new powers beyond simple economic matters which had achieved a high level of integration. As it got closer to the goal of political integration and a peaceful and united Europe, what Mikhail Gorbachev described as

396-648: A common market and customs union , among its six founding members : Belgium , France , Italy , Luxembourg , the Netherlands and West Germany . It gained a common set of institutions along with the European Coal and Steel Community (ECSC) and the European Atomic Energy Community (EURATOM) as one of the European Communities under the 1965 Merger Treaty (Treaty of Brussels). In 1993

495-693: A referendum on 25 September 1972 . The Treaties of Rome had stated that the European Parliament must be directly elected, however this required the Council to agree on a common voting system first. The Council procrastinated on the issue and the Parliament remained appointed, French President Charles de Gaulle was particularly active in blocking the development of the Parliament, with it only being granted Budgetary powers following his resignation. Parliament pressured for agreement and on 20 September 1976

594-606: A SKOS Concept nor a ConceptScheme may be a Collection, nor vice versa; and SKOS semantic relations can only be used with a Concept (not a Collection). The items in a Collection can not be connected to other SKOS Concepts through the Collection node; individual relations must be defined to each Concept in the Collection. All development work is carried out via the mailing list which is a completely open and publicly archived mailing list devoted to discussion of issues relating to knowledge organisation systems, information retrieval and

693-459: A better choice. The extensibility of RDF makes possible further incorporation or extension of SKOS vocabularies into more complex vocabularies, including OWL ontologies. European Community The European Economic Community ( EEC ) was a regional organisation created by the Treaty of Rome of 1957, aiming to foster economic integration among its member states. It was subsequently renamed

792-485: A bridge between the world of knowledge organization systems – including thesauri, classifications, subject headings, taxonomies, and folksonomies – and the linked data community, bringing benefits to both. Libraries, museums, newspapers, government portals, enterprises, social networking applications, and other communities that manage large collections of books, historical artifacts, news reports, business glossaries, blog entries, and other items can now use SKOS to leverage

891-463: A broader or narrower relation is used in a triple, the corresponding transitive super-property also holds; and transitive relations can be inferred (and queried) using these super-properties. SKOS mapping properties are intended to express matching (exact or fuzzy) of concepts from one concept scheme to another, and by convention are used only to connect concepts from different schemes. The concepts relatedMatch , broadMatch , and narrowMatch are

990-663: A complete single market was achieved, known as the internal market , which allowed for the free movement of goods, capital, services, and people within the EEC. In 1994 the internal market was formalised by the EEA agreement. This agreement also extended the internal market to include most of the member states of the European Free Trade Association , forming the European Economic Area , which encompasses 15 countries. Upon

1089-446: A concept scheme. While there are no restrictions precluding their use with two concepts from separate schemes, this is discouraged because it is likely to overstate what can be known about the two schemes, and perhaps link them inappropriately. The property related simply makes an association relationship between two concepts; no hierarchy or generality relation is implied. The properties broader and narrower are used to assert

SECTION 10

1188-640: A concept to be within a particular scheme, nor does it provide any way to declare a complete scheme—there is no way to say the scheme consists only of certain members. A topConcept is (one of) the upper concept(s) in a hierarchical scheme. Each SKOS label is a string of Unicode characters, optionally with language tags, that are associated with a concept. The prefLabel is the preferred human-readable string (maximum one per language tag), while altLabel can be used for alternative strings, and hiddenLabel can be used for strings that are useful to associate, but not meant for humans to read. A SKOS notation

1287-449: A controlled vocabulary. The principal element categories of SKOS are concepts, labels, notations, documentation, semantic relations, mapping properties, and collections. The associated elements are listed in the table below. The SKOS vocabulary is based on concepts. Concepts are the units of thought—ideas, meanings, or objects and events (instances or categories)—which underlie many knowledge organization systems. As such, concepts exist in

1386-457: A convenience, with the same meaning as the semantic properties related , broader , and narrower . (See previous section regarding the meanings of broader and narrower.) The property relatedMatch makes a simple associative relationship between two concepts. When concepts are so closely related that they can generally be used interchangeably, exactMatch is the appropriate property ( exactMatch relations are transitive, unlike any of

1485-604: A direct hierarchical link between two concepts. The meaning may be unexpected; the relation <A> broader <B> means that A has a broader concept called B—hence that B is broader than A. Narrower follows in the same pattern. While the casual reader might expect broader and narrower to be transitive properties, SKOS does not declare them as such. Rather, the properties broaderTransitive and narrowerTransitive are defined as transitive super-properties of broader and narrower. These super-properties are (by convention) not used in declarative SKOS statements. Instead, when

1584-422: A file, document, or any kind of so-called information resource, should be "slash" URIs — in other words, should not contain a fragment identifier , whereas a URI used to identify a concept or abstract resource should be a "hash" URI using a fragment identifier. For example: http://www.example.org/catalogue/widgets.html would both identify and locate a web page (maybe providing some human-readable description of

1683-486: A library can also be considered resources. The resource is the conceptual mapping to an entity or set of entities, not necessarily the entity which corresponds to that mapping at any particular instance in time. Thus, a resource can remain constant even when its content---the entities to which it currently corresponds---changes over time, provided that the conceptual mapping is not changed in the process. Although examples in this document were still limited to physical entities,

1782-504: A literal (e.g., a string); a resource node that has its own properties; or a reference to another document, for example using a URI. This enables the documentation to have its own metadata , like creator and creation date. Specific guidance on SKOS documentation properties can be found in the SKOS Primer Documentary Notes. SKOS semantic relations are intended to provide ways to declare relationships between concepts within

1881-427: A mathematical equation, the types of a relationship (e.g., "parent" or "employee"), or numeric values (e.g., zero, one, and infinity).' First released in 1999, RDF was first intended to describe resources, in other words to declare metadata of resources in a standard way. A RDF description of a resource is a set of triples (subject, predicate, object), where subject represents the resource to be described, predicate

1980-405: A resource (identification and naming) and its functional aspects (addressing and technical handling) weren't clearly distinct in the early specifications of the web, and the very definition of the concept has been the subject of long and still open debate involving difficult, and often arcane, technical, social, linguistic and philosophical issues. In the early specifications of the web (1990–1994),

2079-512: A type of skos:note ; they just provide more specific kinds of information. The property definition , for example, should contain a full description of the subject resource. More specific note types can be defined in a SKOS extension, if desired. A query for <A> skos:note ? will obtain all the notes about <A>, including definitions, examples, and scope, history and change, and editorial documentation. Any of these SKOS Documentation properties can refer to several object types:

SECTION 20

#1733085025365

2178-651: A type of property relevant to this resource, and object can be data or another resource. The predicate itself is considered as a resource and identified by a URI. Hence, properties like "title", "author" are represented in RDF as resources, which can be used, in a recursive way, as the subject of other triples. Building on this recursive principle, RDF vocabularies, such as RDF Schema (RDFS), Web Ontology Language (OWL), and Simple Knowledge Organization System will pile up definitions of abstract resources such as classes, properties, concepts, all identified by URIs. RDF also specifies

2277-469: A way to make a legacy of concept schemes available to Semantic Web applications, simpler than the more complex ontology language, OWL . OWL is intended to express complex conceptual structures, which can be used to generate rich metadata and support inference tools. However, constructing useful web ontologies is demanding in terms of expertise, effort, and cost. In many cases, this type of effort might be superfluous or unsuited to requirements, and SKOS might be

2376-452: A web browser, and if the syntax of the URI itself could help to differentiate "abstract" resources from "information" resources. The URI specifications such as RFC 3986 left to the protocol specification the task of defining actions performed on the resources and they do not provide any answer to this question. It had been suggested that an HTTP URI identifying a resource in the original sense, such as

2475-545: A web resource in the classical sense (a web page or on-line file) is clearly owned by its publisher, who can claim intellectual property on it, an abstract resource can be defined by an accumulation of RDF descriptions, not necessarily controlled by a unique publisher, and not necessarily consistent with each other. It's an open issue to know if a resource should have an authoritative definition with clear and trustable ownership, and in this case, how to make this description technically distinct from other descriptions. A parallel issue

2574-401: Is broadly compatible with the data model of ISO 25964-1 – Thesauri for Information Retrieval. This data model can be viewed and downloaded from the website for ISO 25964 . SKOS development has involved experts from both RDF and library community, and SKOS intends to allow easy migration of thesauri defined by standards such as NISO Z39.19 – 2005 or ISO 25964 . SKOS is intended to provide

2673-468: Is similar to a label, but this literal string has a datatype, like integer, float, or date; the datatype can even be made up (see 6.5.1 Notations, Typed Literals and Datatypes in the SKOS Reference). The notation is useful for classification codes and other strings not recognizable as words. The Documentation or Note properties provide basic information about SKOS concepts. All the concepts are considered

2772-630: The Community budget had been correctly spent by the Community's institutions. The ECA provided an audit report for each financial year to the Council and Parliament and gave opinions and proposals on financial legislation and anti-fraud actions. It is the only institution not mentioned in the original treaties, having been set up in 1975. At the time of its abolition, the European Community pillar covered

2871-510: The Dublin Core concepts such as "title", "publisher", "creator" are identified by "slash" URIs like http://purl.org/dc/elements/1.1/title . The general question of which kind of resources HTTP URI should or should not identify has been formerly known in W3C as the httpRange-14 issue, following its name on the list defined by the (TAG). The TAG delivered in 2005 a final answer to this issue, making

2970-686: The European Common Market (ECM) in the English-speaking countries, and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the Union the formal successor institution of the Community. The Community's initial aim was to bring about economic integration, including

3168-468: The European Community ( EC ) upon becoming integrated into the first pillar of the newly formed European Union (EU) in 1993. In the popular language, the singular European Community was sometimes inaccurately used in the wider sense of the plural European Communities , in spite of the latter designation covering all the three constituent entities of the first pillar. The EEC was also known as

3267-593: The European Community , continuing to follow the supranational structure of the EEC. The EEC institutions became those of the EU, however the Court, Parliament and Commission had only limited input in the new pillars, as they worked on a more intergovernmental system than the European Communities. This was reflected in the names of the institutions, the council was formally the "Council of the European Union " while

3366-523: The European Free Trade Association ). The six were France, West Germany, Italy and the three Benelux countries: Belgium, the Netherlands and Luxembourg. The first enlargement was in 1973, with the accession of Denmark, Ireland and the United Kingdom. Greece, Spain and Portugal joined in the 1980s. The former East Germany became part of the EEC upon German reunification in 1990. Following the creation of

However the EEC, and Euratom, had different executive bodies to the ECSC. In place of the ECSC's Council of Ministers was the Council of the European Economic Community , and in place of the High Authority was the Commission of the European Communities . There

3564-722: The Ohlin Report the Spaak Report would provide the basis for the Treaty of Rome . In 1956, Paul-Henri Spaak led the Intergovernmental Conference on the Common Market and Euratom at the Val Duchesse conference centre, which prepared for the Treaty of Rome in 1957. The conference led to the signature, on 25 March 1957, of the Treaty of Rome establishing a European Economic Community. The resulting communities were

3663-550: The Resource Description Framework (RDF). The concept of a web resource has evolved during the Web's history, from the early notion of static addressable documents or files , to a more generic and abstract definition, now encompassing every "thing" or entity that can be identified, named, addressed or handled, in any way whatsoever, in the web at large, or in any networked information system. The declarative aspects of

3762-515: The W3C Recommendation track. The roadmap projected SKOS as a Candidate Recommendation by the end of 2007, and as a Proposed Recommendation in the first quarter of 2008. The main issues to solve were determining its precise scope of use, and its articulation with other RDF languages and standards used in libraries (such as Dublin Core ). On August 18, 2009, W3C released the new standard that builds

3861-570: The treaties . It was designed to be independent, representing the interest of the Community as a whole. Every member state submitted one commissioner (two from each of the larger states, one from the smaller states). One of its members was the President , appointed by the council, who chaired the body and represented it. Under the Community, the European Parliament (formerly the European Parliamentary Assembly) had an advisory role to

3960-415: The 1960s the council also began to meet informally at the level of heads of government and heads of state; these European summits followed the same presidency system and secretariat as the council but was not a formal formation of it. The Commission of the European Communities was the executive arm of the community, drafting Community law , dealing with the day to running of the Community and upholding

4059-475: The 2009 Treaty of Lisbon , which incorporated the EC's institutions into the EU's wider framework and provided that the EU would "replace and succeed the European Community". In April 1951, the Treaty of Paris was signed, creating the European Coal and Steel Community (ECSC). This was an international community based on supranationalism and international law, designed to help the economy of Europe and prevent future war by integrating its members . With

4158-523: The Community and began the longest application process for any country. With the prospect of further enlargement, and a desire to increase areas of co-operation, the Single European Act was signed by the foreign ministers on 17 and 28 February 1986 in Luxembourg and The Hague respectively. In a single document it dealt with reform of institutions, extension of powers, foreign policy cooperation and

4257-637: The Community. Prior to 2004, the larger members (France, Germany, Italy and the United Kingdom) have had two Commissioners. In the European Parliament , members are allocated a set number seats related to their population, however these ( since 1979 ) have been directly elected and they sit according to political allegiance, not national origin. Most other institutions, including the European Court of Justice , have some form of national division of its members. There were three political institutions which held

4356-454: The Council agreed part of the necessary instruments for election, deferring details on electoral systems which remain varied to this day. During the tenure of President Jenkins , in June 1979, the elections were held in all the then-members (see 1979 European Parliament election ). The new Parliament, galvanised by direct election and new powers, started working full-time and became more active than

4455-409: The Council and Commission. There were a number of Community legislative procedures , at first there was only the consultation procedure , which meant Parliament had to be consulted, although it was often ignored. The Single European Act gave Parliament more power, with the assent procedure giving it a right to veto proposals and the cooperation procedure giving it equal power with the Council if

4554-467: The Council on Community matters. This replaced the informal parliamentary blocking powers established by the 1979 Isoglucose decision. It also abolished any existing state like Simple Majority voting in the EEC, replacing it with Qualified Majority Voting , a procedure more commonly used in international organisations. The Treaty of Amsterdam transferred responsibility for free movement of persons (e.g., visas , illegal immigration , asylum ) from

4653-728: The DESIRE/SOSIG implementation was described in W3C's QL'98 workshop, motivating early work on RDF rule and query languages: A Query and Inference Service for RDF. SKOS built upon the output of the Language Independent Metadata Browsing of European Resources (LIMBER) project funded by the European Community , and part of the Information Society Technologies programme. In the LIMBER project CCLRC further developed an RDF thesaurus interchange format which

4752-662: The EC in 1961 as an associate member, however its membership was suspended in 1967 after a coup d'état established a military dictatorship called the Regime of the Colonels . A year later, in February 1962, Spain attempted to join the European Community. However, because Francoist Spain was not a democracy, all members rejected the request in 1964. The four countries resubmitted their applications on 11 May 1967 and with Georges Pompidou succeeding Charles de Gaulle as French president in 1969,

4851-435: The ECSC and Euratom were merged with that of the EEC, creating a single institutional structure governing the three separate Communities. From here on, the term European Communities were used for the institutions (for example, from Commission of the European Economic Community to the Commission of the European Communities ). The Council of the European Communities was a body holding legislative and executive powers and

4950-482: The EU in 1993, it has enlarged to include an additional sixteen countries by 2013. Member states are represented in some form in each institution. The Council is also composed of one national minister who represents their national government. Each state also has a right to one European Commissioner each, although in the European Commission they are not supposed to represent their national interest but that of

5049-478: The European Economic Community (EEC) and the European Atomic Energy Community (EURATOM or sometimes EAEC). These were markedly less supranational than the previous communities, due to protests from some countries that their sovereignty was being infringed (however there would still be concerns with the behaviour of the Hallstein Commission ). Germany became a founding member of the EEC, and Konrad Adenauer

5148-563: The European institutions until the French veto was reinstated. Eventually, a compromise was reached with the Luxembourg compromise on 29 January 1966 whereby a gentlemen's agreement permitted members to use a veto on areas of national interest. On 1 July 1967, when the Merger Treaty came into operation, combining the institutions of the ECSC and Euratom into that of the EEC, they already shared

5247-621: The High Authority in protest and began work on alternative communities, based on economic integration rather than political integration. Following the Messina Conference in 1955, Paul-Henri Spaak was given the task to prepare a report on the idea of a customs union . The so-called Spaak Report of the Spaak Committee formed the cornerstone of the intergovernmental negotiations at Val Duchesse conference centre in 1956. Together with

5346-608: The ILRT at Bristol University , HP Labs , CCLRC and Stilo. The first release of SKOS Core and SKOS Mapping were published at the end of 2003, along with other deliverables on RDF encoding of multilingual thesauri and thesaurus mapping. Following the termination of SWAD-Europe, SKOS effort was supported by the W3C Semantic Web Activity in the framework of the Best Practice and Deployment Working Group. During this period, focus

5445-544: The Justice and Home Affairs (JHA) pillar to the European Community (JHA was renamed Police and Judicial Co-operation in Criminal Matters (PJCC) as a result). Both Amsterdam and the Treaty of Nice also extended codecision procedure to nearly all policy areas, giving Parliament equal power to the Council in the Community. In 2002, the Treaty of Paris which established the ECSC expired, having reached its 50-year limit (as

5544-602: The Maastricht Treaty in 1993, these institutions became those of the European Union, though limited in some areas due to the pillar structure. Despite this, Parliament in particular has gained more power over legislation and security of the commission. The Court of Justice was the highest authority in the law, settling legal disputes in the Community, while the Auditors had no power but to investigate. The EEC inherited some of

5643-623: The Semantic Web. Anyone may participate informally in the development of SKOS by joining the discussions on public-esw-thes@w3.org – informal participation is warmly welcomed. Anyone who works for a W3C member organisation may formally participate in the development process by joining the Semantic Web Deployment Working Group – this entitles individuals to edit specifications and to vote on publication decisions. There are publicly available SKOS data sources. The SKOS metamodel

5742-613: The Western and Eastern blocs, other than reconcile Member States such as France and Germany after WW2. The tasks entrusted to the Community were divided among an assembly, the European Parliament, Council, Commission, and Court of Justice. Moreover, restrictions to market were lifted to further liberate trade among Member States. Citizens of Member States (other than goods, services, and capital) were entitled to freedom of movement. The CAP, Common Agricultural Policy, regulated and subsided

5841-416: The agricultural sphere. A European Social Fund was implemented in favour of employees who lost their jobs. A European Investment Bank was established to "facilitate the economic expansion of the Community by opening up fresh resources" (Art. 3 Treaty of Rome 3/25/1957). All these implementations included overseas territories. Competition was to be kept alive to make products cheaper for European consumers. For

5940-471: The aim of creating a federal Europe two further communities were proposed: a European Defence Community and a European Political Community . While the treaty for the latter was being drawn up by the Common Assembly , the ECSC parliamentary chamber, the proposed defence community was rejected by the French Parliament . ECSC President Jean Monnet , a leading figure behind the communities, resigned from

6039-621: The classes and properties sufficient to represent the common features found in a standard thesaurus. It is based on a concept-centric view of the vocabulary, where primitive objects are not terms, but abstract notions represented by terms. Each SKOS concept is defined as an RDF resource . Each concept can have RDF properties attached, including: Concepts can be organized in hierarchies using broader-narrower relationships, or linked by non-hierarchical (associative) relationships. Concepts can be gathered in concept schemes, to provide consistent and structured sets of concepts, representing whole or part of

6138-573: The commission was formally the "Commission of the European Communities ". There are more competencies listed in Article 3 of the European Communities pillar than there are in Article 3 of the Treaty of Rome. This is due to the fact that some competencies were already inherent in the Treaty of Tome, some were referred to in the Treaty of Rome, and some were extended under Article 235 of the Treaty of Rome. Competencies were added to cover trans-European networks, and

6237-504: The council was not unanimous. In 1970 and 1975, the Budgetary treaties gave Parliament power over the Community budget . The Parliament's members, up-until 1980 were national MPs serving part-time in the Parliament. The Treaties of Rome had required elections to be held once the council had decided on a voting system, but this did not happen and elections were delayed until 1979 (see 1979 European Parliament election ). After that, Parliament

6336-446: The council, Parliament or another party place a request for legislation to the commission. The Commission then drafts this and presents it to the council for approval and the Parliament for an opinion (in some cases it had a veto, depending upon the legislative procedure in use). The commission's duty is to ensure it is implemented by dealing with the day-to-day running of the Union and taking others to Court if they fail to comply. After

6435-418: The customs union, the treaty provided for a 10% reduction in custom duties and up to 20% of global import quotas. Progress on the customs union proceeded much faster than the twelve years planned. However, France faced some setbacks due to their war with Algeria . The six states that founded the EEC and the other two Communities were known as the " inner six " (the "outer seven" were those countries who formed

6534-576: The definition of anonymous resources or blank nodes , which are not absolutely identified by URIs. URLs , particularly HTTP URIs , are frequently used to identify abstract resources, such as classes, properties or other kind of concepts. Examples can be found in RDFS or OWL ontologies . Since such URIs are associated with the HTTP protocol, the question arose of which kind of representation, if any, should one get for such resources through this protocol, typically using

6633-409: The definition opened the door to more abstract resources. Providing a concept is given an identity, and this identity is expressed by a well-formed URI (Uniform Resource Identifier, a superset of URLs), then a concept can be a resource as well. In January 2005, RFC 3986 makes this extension of the definition completely explicit: '…abstract concepts can be resources, such as the operators and operands of

6732-547: The distinction between an "information resource" and a "non-information" resource dependent on the type of answer given by the server to a "GET" request: This allows vocabularies (like Dublin Core , FOAF , and Wordnet ) to continue to use slash instead of hash for pragmatic reasons. While this compromise seems to have met a consensus in the Semantic Web community, some of its prominent members such as Pat Hayes have expressed concerns both on its technical feasibility and conceptual foundation. According to Patrick Hayes' viewpoint,

6831-412: The end of 1959 when the foreign ministers of the six members announced that would be meeting quarterly to discuss political issues and international problems. One of the first important accomplishments of the EEC was the establishment (1962) of common price levels for agricultural products. In 1968, internal tariffs (tariffs on trade between member nations) were removed on certain products. Another crisis

6930-469: The entry into force of the Maastricht Treaty in 1993, the EEC was renamed the European Community to reflect that it covered a wider range than economic policy. This was also when the three European Communities, including the EC, were collectively made to constitute the first of the three pillars of the European Union , which the treaty also founded. The EC existed in this form until it was abolished by

7029-404: The executive and legislative power of the EEC, plus one judicial institution and a fifth body created in 1975. These institutions (except for the auditors) were created in 1957 by the EEC but from 1967 onwards they applied to all three Communities. The Council represents the member state governments, the Parliament represents citizens and the Commission represents the European interest. Essentially,

7128-435: The first treaty, it was the only one with a limit). No attempt was made to renew its mandate; instead, the Treaty of Nice transferred certain of its elements to the Treaty of Rome and hence its work continued as part of the EC area of the European Community's remit. After the entry into force of the Treaty of Lisbon in 2009 the pillar structure ceased to exist. The European Community, together with its legal personality ,

7227-574: The following areas; Since the end of World War II , sovereign European countries have entered into treaties and thereby co-operated and harmonised policies (or pooled sovereignty ) in an increasing number of areas, in the European integration project or the construction of Europe ( French : la construction européenne ). The following timeline outlines the legal inception of the European Union (EU)—the principal framework for this unification. The EU inherited many of its present responsibilities from

7326-453: The integration process. It was mentioned in the treaties for the first time in the Single European Act (see below). Greece re-applied to join the community on 12 June 1975, following the restoration of democracy, and joined on 1 January 1981. Following on from Greece, and after their own democratic restoration, Spain and Portugal applied to the communities in 1977 and joined on 1 January 1986. In 1987, Turkey formally applied to join

7425-564: The internet. There again, the term resource itself is not explicitly defined. The first explicit definition of resource is found in RFC 2396, in August 1998: A resource can be anything that has identity. Familiar examples include an electronic document, an image, a service (e.g., "today's weather report for Los Angeles"), and a collection of other resources. Not all resources are network "retrievable"; e.g., human beings, corporations, and bound books in

7524-464: The mind as abstract entities which are independent of the terms used to label them. In SKOS, a Concept (based on the OWL Class ) is used to represent items in a knowledge organization system (terms, ideas, meanings, etc.) or such a system's conceptual or organizational structure. A ConceptScheme is analogous to a vocabulary, thesaurus, or other way of organizing concepts. SKOS does not constrain

7623-594: The notion of resource; actually it barely uses the term besides its occurrence in Uniform Resource Identifier (URI), Uniform Resource Locator (URL), and Uniform Resource Name (URN), and still speaks about "Objects of the Network". RFC 1738 (December 1994) further specifies URLs, the term "Universal" being changed to "Uniform". The document is making a more systematic use of resource to refer to objects which are "available", or "can be located and accessed" through

7722-412: The other Match relations). The closeMatch property that indicates concepts that only sometimes can be used interchangeably, and so it is not a transitive property. The concept collections ( Collection , orderedCollection ) are labeled and/or ordered ( orderedCollection ) groups of SKOS concepts. Collections can be nested, and can have defined URIs or not (which is known as a blank node). Neither

7821-570: The power of linked data. SKOS was originally designed as a modular and extensible family of languages, organized as SKOS Core, SKOS Mapping, and SKOS Extensions, and a Metamodel. The entire specification is now complete within the namespace http://www.w3.org/2004/02/skos/core# . In addition to the reference itself, the SKOS Primer (a W3C Working Group Note) summarizes the Simple Knowledge Organization System. The SKOS defines

7920-428: The previous assemblies. Shortly after its election, the Parliament proposed that the Community adopt the flag of Europe design used by the Council of Europe . The European Council in 1984 appointed an ad hoc committee for this purpose. The European Council in 1985 largely followed the committee's recommendations, but as the adoption of a flag was strongly reminiscent of a national flag representing statehood ,

8019-573: The schema. It was developed in the Thesaurus Activity Work Package, in the Semantic Web Advanced Development for Europe (SWAD-Europe) project. SWAD-Europe was funded by the European Community , and part of the Information Society Technologies programme. The project was designed to support W3C's Semantic Web Activity through research, demonstrators and outreach efforts conducted by the five project partners, ERCIM ,

8118-517: The single market. It came into force on 1 July 1987. The act was followed by work on what would be the Maastricht Treaty , which was agreed on 10 December 1991, signed the following year and coming into force on 1 November 1993 establishing the European Union, and paving the way for the European Monetary Union . The EU absorbed the European Communities as one of its three pillars . The EEC's areas of activities were enlarged and were renamed

8217-447: The term resource is barely used at all. The web is designed as a network of more or less static addressable objects, basically files and documents, linked using Uniform Resource Locators (URLs). A web resource is implicitly defined as something which can be identified. The identification serves two distinct purposes: naming and addressing; the latter only depends on a protocol. It is notable that RFC 1630 does not attempt to define at all

8316-419: The topic. For example, if agriculture was being discussed, the council would be composed of each national minister for agriculture. They represented their governments and were accountable to their national political systems. Votes were taken either by majority (with votes allocated according to population) or unanimity. In these various forms they share some legislative and budgetary power of the Parliament. Since

8415-413: The very distinction between "information resource" and "other resource" is impossible to find and should better not be specified at all, and ambiguity of the referent resource is inherent to URIs like to any naming mechanism. In RDF, "anybody can declare anything about anything". Resources are defined by formal descriptions which anyone can publish, copy, modify and publish over the web. If the content of

8514-612: The veto was lifted. Negotiations began in 1970 under the pro-European UK government of Edward Heath , who had to deal with disagreements relating to the Common Agricultural Policy and the UK's relationship with the Commonwealth of Nations . Nevertheless, two years later the accession treaties were signed so that Denmark, Ireland and the UK joined the Community effective 1 January 1973. The Norwegian people had rejected membership in

8613-424: The widgets sold by Silly Widgets, Inc.) whereas http://www.example.org/ontology#Widget would identify the abstract concept or class "Widget" in this company ontology, and would not necessarily retrieve any physical resource through HTTP protocol . But it has been answered that such a distinction is impossible to enforce in practice, and famous standard vocabularies provide counter-examples widely used. For example,

8712-487: The work of the Culture Committee and Education Committee that were previously sharing existing competencies. The only entry in Article 3 that represented something new is the competence covering the entry and movement of persons in the internal market. However, after the Treaty of Maastricht, Parliament gained a more formal role. Maastricht brought in the codecision procedure , which gave it equal legislative power with

8811-514: Was absorbed into the newly consolidated European Union which merged in the other two pillars (however Euratom remained distinct). This was originally proposed under the European Constitution but that treaty failed ratification in 2005. The main aim of the EEC, as stated in its preamble, was to "preserve peace and liberty and to lay the foundations of an ever closer union among the peoples of Europe". Calling for balanced economic growth, this

8910-457: Was composed of one judge per state with a president elected from among them. Its role was to ensure that Community law was applied in the same way across all states and to settle legal disputes between institutions or states. It became a powerful institution as Community law overrides national law. The fifth institution is the European Court of Auditors . Its ensured that taxpayer funds from

9009-404: Was controversial, the "flag of Europe" design was adopted only with the status of a "logo" or "emblem". The European Council, or European summit, had developed since the 1960s as an informal meeting of the Council at the level of heads of state. It had originated from then- French President Charles de Gaulle 's resentment at the domination of supranational institutions (e.g. the commission) over

9108-677: Was demonstrated on the European Language Social Science Thesaurus (ELSST) at the UK Data Archive as a multilingual version of the English language Humanities and Social Science Electronic Thesaurus (HASSET) which was planned to be used by the Council of European Social Science Data Archives CESSDA. SKOS as a distinct initiative began in the SWAD-Europe project, bringing together partners from both DESIRE, SOSIG (ILRT) and LIMBER (CCLRC) who had worked with earlier versions of

9207-517: Was elected every five years. In the following 20 years, it gradually won co-decision powers with the Council over the adoption of legislation, the right to approve or reject the appointment of the Commission President and the commission as a whole, and the right to approve or reject international agreements entered into by the Community. The Court of Justice of the European Communities was the highest court of on matters of Community law and

9306-399: Was greater difference between these than name: the French government of the day had grown suspicious of the supranational power of the High Authority and sought to curb its powers in favour of the intergovernmental style Council. Hence the council had a greater executive role in the running of the EEC than was the situation in the ECSC. By virtue of the Merger Treaty in 1967, the executives of

9405-491: Was made leader in a very short time. The first formal meeting of the Hallstein Commission was held on 16 January 1958 at the Chateau de Val-Duchesse . The EEC (direct ancestor of the modern Community) was to create a customs union while Euratom would promote co-operation in the nuclear power sphere. The EEC rapidly became the most important of these and expanded its activities. The first move towards political developments came at

9504-839: Was put both on consolidation of SKOS Core, and development of practical guidelines for porting and publishing thesauri for the Semantic Web. The SKOS main published documents — the SKOS Core Guide, the SKOS Core Vocabulary Specification, and the Quick Guide to Publishing a Thesaurus on the Semantic Web — were developed through the W3C Working Draft process. Principal editors of SKOS were Alistair Miles, initially Dan Brickley, and Sean Bechhofer. The Semantic Web Deployment Working Group, chartered for two years (May 2006 – April 2008), put in its charter to push SKOS forward on

9603-468: Was thus the main decision-making body of the Community. Its Presidency rotated between the member states every six months and it is related to the European Council , which was an informal gathering of national leaders (started in 1961) on the same basis as the council. The council was composed of one national minister from each member state. However the Council met in various forms depending upon

9702-711: Was to be accomplished through: Citing Article 2 from the original text of the Treaty of Rome of the 25th of March 1957, the EEC aimed at "a harmonious development of economic activities, a continuous and balanced expansion, an increase in stability, an accelerated raising of the standard of living and closer relations between the States belonging to it". Given the fear of the Cold War, many Western Europeans were afraid that poverty would make "the population vulnerable to communist propaganda" (Meurs 2018, p. 68), meaning that increasing prosperity would be beneficial to harmonise power between

9801-515: Was triggered in regard to proposals for the financing of the Common Agricultural Policy , which came into force in 1962. The transitional period whereby decisions were made by unanimity had come to an end, and majority-voting in the council had taken effect. Then- French President Charles de Gaulle 's opposition to supranationalism and fear of the other members challenging the CAP led to an "empty chair policy" whereby French representatives were withdrawn from
