Web Services Discovery provides access to software systems over the Internet using standard protocols. In the most basic scenario there is a Web Service Provider that publishes a service and a Web Service Consumer that uses this service. Web Service Discovery is the process of finding suitable web services for a given task.

29-528: Publishing a web service involves creating a software artifact and making it accessible to potential consumers. Web service providers augment a service endpoint interface with an interface description using the Web Services Description Language (WSDL) so that a consumer can use the service. Universal Description, Discovery, and Integration ( UDDI ) is an XML-based registry for business internet services. A provider can explicitly register

58-499: A Web Service, with information on the service bindings. Some of the information is related to the Web Service - such as the address of the service and the parameters, and references to specifications of interfaces. Other information is not related directly to the Web Service - this includes e-mail, FTP , CORBA and telephone details for the service. Because a Web Service may have multiple bindings (as defined in its WSDL description),

87-493: A service may have multiple Green Pages, as each binding will need to be accessed differently. UDDI nodes are servers which support the UDDI specification and belong to a UDDI registry while UDDI registries are collections of one or more nodes. SOAP is an XML-based protocol to exchange messages between a requester and a provider of a Web Service. The provider publishes the WSDL to UDDI and

116-472: A service supporting the desired SOAP (or other) service interface, and meeting other criteria. In such a world, the publicly operated UDDI node or broker would be critical for everyone. For the consumer, public or open brokers would only return services listed for public discovery by others, while for a service producer, getting a good placement in the brokerage—by relying on metadata of authoritative index categories—would be critical for effective placement. UDDI

145-496: A service with a Web Services Registry such as UDDI or publish additional documents intended to facilitate discovery such as Web Services Inspection Language (WSIL) documents. The service users or consumers can search web services manually or automatically. The implementation of UDDI servers and WSIL engines should provide simple search APIs or web-based GUI to help find Web services. Web services may also be discovered using multicast mechanisms like WS-Discovery , thus reducing

174-460: A unique business with a registered U.S. headquarters, was determined by the industry appropriate for the overall largest product lines of the company or organization of which the establishment was a part. The later NAICS classification system has a different concept, assigning establishments into categories based on each one's output. The first edition of SIC was published in parts during 1938–1940, with revisions made in 1941–1942. The next edition

232-571: Is a system for classifying industries by a four-digit code as a method of standardizing industry classification for statistical purposes across agencies. Established in the United States in 1937, it is used by government agencies to classify industry areas. Similar SIC systems are also used by agencies in other countries, e.g., by the United Kingdom 's Companies House . In the United States,

261-530: Is already known (for example, locating a service based on the provider's name). Contact information for the business is also provided - for example the businesses address and phone number; and other information such as the Dun & Bradstreet. Yellow pages provide a classification of the service or business, based on standard taxonomies. These include the Standard Industrial Classification (SIC),

290-656: Is an open industry initiative, sponsored by the Organization for the Advancement of Structured Information Standards ( OASIS ), for enabling businesses to publish service listings and discover each other, and to define how the services or software applications interact over the Internet. UDDI was originally proposed as a core Web service standard. It is designed to be interrogated by SOAP messages and to provide access to Web Services Description Language (WSDL) documents describing

319-570: The North American Industry Classification System (NAICS), or the United Nations Standard Products and Services Code (UNSPSC) and geographic taxonomies. Because a single business may provide a number of services, there may be several Yellow Pages (each describing a service) associated with one White Page (giving general information about the business). Green pages are used to describe how to access

348-841: The OASIS Universal Description, Discovery, and Integration (UDDI) Specification Technical Committee voted to complete its work in late 2007 and has been closed. In September 2010, Microsoft announced they were removing UDDI services from future versions of the Windows Server operating system. Instead, this capability would be moved to BizTalk Server . In 2013, Microsoft further announced the deprecation of UDDI Services in BizTalk Server. In 2016, Microsoft removed UDDI Services from BizTalk Server. UDDI systems are most commonly found inside companies, where they are used to dynamically bind client systems to implementations. However, much of

377-452: The SIC defines these employees as part of the "Basic Sector" of manufacturing jobs when they should be reported as "Non-Basic." Secondly, SIC codes were developed for traditional industries prior to 1970. Business has changed considerably since then from manufacturing-based to mostly service-based. As a result, and thirdly the SIC has been slow to recognize new and emerging industries, such as those in

406-466: The SIC system was last revised in 1987 and was last used by the Census Bureau for the 1992 Economic Census, and has been replaced by the North American Industry Classification System (NAICS code), which was released in 1997. Some U.S. government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), continue to use SIC codes. The SIC code for an establishment, that is,

435-506: The Standard Industrial Classification system was born. SIC codes are four-digit numerical representations of major businesses and industries. SIC codes are assigned based on common characteristics shared in the products, services, production and delivery system of a business. SIC codes have a hierarchical, top-down structure that begins with general characteristics and narrows down to the specifics. The first two digits of

464-566: The United States in 1997 and in Mexico one year later. NAICS classified establishments (workplace) by their main output, instead of classifying them with the larger firm or organization of which the establishment was a part. This gives more precise information on establishment and worker activities than the SIC system, but changed the meaning of the classifications somewhat, making some time series of data hard to sustain accurately. Fort and Klimek (2016) found using longitudinal data on establishments that

493-429: The code represent the major industry sector to which a business belongs. The third and fourth digits describe the sub-classification of the business group and specialization, respectively. For example, "36" refers to a business that deals in "Electronic and Other Equipment." Adding "7" as a third digit to get "367" indicates that the business operates in "Electronic, Component and Accessories." The fourth digit distinguishes

522-503: The computer, software, and information technology sectors. The SIC codes can be grouped into progressively broader industry classifications: industry group, major group, and division. The first 3 digits of the SIC code indicate the industry group, and the first two digits indicate the major group. Each division encompasses a range of SIC codes: To look at a particular example of the hierarchy, SIC code 2024 (ice cream and frozen desserts) belongs to industry group 202 (dairy products), which

551-542: The current industrial climate. The result was the North American Industry Classification System , or NAICS, a collaborative effort between Canada, the U.S. and Mexico. NAICS replaced the four-digit SIC code with a six-digit code, and it provided more flexibility in handling emerging industries (for example, the NAICS system more generally allows for "Other..." categories across industry groups). The new codes were implemented in Canada and

580-409: The descriptions provided by employers under the primary business activity entry on employer ID applications. Over the years, the U.S. Census has identified three major limitations to using the SIC system. The first limitation surrounds its definition and mistaken classification of employee groups. For example, administrative assistants in the automotive industry support all levels of the business, yet

609-505: The first Standard Industrial Classification for the United States. The SIC system was last revised in 1987 and was last used by the Census Bureau for the 1992 Economic Census. The Office of Management and Budget , or OMB, was tasked with revising the SIC system to reflect changing economic conditions. The OMB established the Economic Classification Policy Committee in 1992 to develop a new system representative of

638-450: The need for centralized registries in smaller networks. Universal Description, Discovery and Integration ( UDDI , pronounced / ˈ j ʊ d iː / ) is a platform-independent , Extensible Markup Language protocol that includes a (XML-based) registry by which businesses worldwide can list themselves on the Internet , and a mechanism to register and locate web service applications. UDDI

667-491: The protocol bindings and message formats required to interact with the web services listed in its directory. UDDI was written in August 2000, at a time when the authors had a vision of a world in which consumers of web services would be linked up with providers through a public or private dynamic brokerage system. In this vision, anyone needing a service, such as credit card authentication , would go to their service broker and select

696-533: The requester can join to it using SOAP. The current UDDI search mechanism can only focus on a single search criterion, such as business name, business location, business category, service type by name, business identifier, or discovery URL. In fact, in a business solution, it is very normal to search multiple UDDI registries or WSIL documents and then aggregate the returned result by using filtering and ranking techniques. IBM modularized this federated Web Services Discovery engine in 2001. The released technology from IBM

725-416: The search metadata permitted in UDDI is not used for this relatively simple role. A UDDI business registration consists of three components: White pages give information about the business supplying the service. This includes the name of the business and a description of the business - potentially in multiple languages. Using this information, it is possible to find a service about which some information

754-555: The specific industry sector, so a code of "3672" indicates that the business is concerned with "Printed Circuit Boards." The U.S. Census Bureau , Bureau of Labor Statistics , Internal Revenue Service and Social Security Administration utilize SIC codes in their reporting, although SIC codes are also used in academic and business sectors. The Bureau of Labor Statistics updates the codes every three years and uses SIC to report on work force, wages and pricing issues. The Social Security Administration assigns SIC codes to businesses based on

783-566: The switch from SIC to NAICS reclassified large numbers of workers differently by industry/sector than NAICS does, notably by reclassifying some from the Manufacturing sector into Services. In the early 1900s, each branch of United States government agencies conducted business analysis using its own methods and metrics, unknown and meaningless to other branches. In the 1930s, the government needed standardized and meaningful methods to measure, analyze and share data across its various agencies. Thus,

812-646: Was included in the Web Services Interoperability (WS-I) standard as a central pillar of web services infrastructure, and the UDDI specifications supported a publicly accessible Universal Business Registry in which a naming system was built around the UDDI-driven service broker. UDDI has not been as widely adopted as its designers had hoped. IBM , Microsoft , and SAP announced they were closing their public UDDI nodes in January 2006. The group defining UDDI,

841-637: Was published in two parts in 1945 and 1949. Further revisions were issued in 1957, 1963, 1967, 1972, 1977, and 1987. The SIC code system has been used since the 1930s. It was developed by the Interdepartmental Committee on Industrial Statistics, established by the Central Statistical Board who developed the List of Industries for manufacturing, published in 1938, and the 1939 List of Industries for non-manufacturing industries, which became
