30-518: Picasa was a cross-platform image organizer and image viewer for organizing and editing digital photos , integrated with a now defunct photo-sharing website , originally created by a company named Lifescape (which at that time was incubated by Idealab ) in 2002. "Picasa" is a blend of the name of Spanish painter Pablo Picasso , the word casa (Spanish for "house") and "pic" for pictures. Native applications for Windows XP , Windows Vista , Windows 7 , and macOS were available. Linux support

60-815: A beta version of Picasa for Mac (Intel-based Macs only). Also, a plugin is available for iPhoto to upload to the Picasa Web Albums hosting service. There is also a standalone Picasa Web Albums uploading tools for OS X 10.4 or later. The Picasa for Mac is a Google Labs release. For organizing photos, Picasa has file importing and tracking features, as well as tags , facial recognition, and collections for further sorting. It also offers several basic photo editing functions, including color enhancement, red eye reduction, and cropping . Other features include slide shows, printing, and image timelines. Images can also be prepared for external use, such as for e-mailing or printing, by reducing file size and setting up page layouts. There

90-400: A document as a whole (the "main" metadata), but can also describe parts of a document, such as pages or included images. This architecture makes it possible to retain authorship and rights information about, for example, images included in a published document. Similarly, it permits documents created from several smaller documents to retain the original metadata associated with the parts. This

120-529: A namespace for the Dublin Core Metadata Element Set). Custom namespaces can be used to extend the data model. An instance of the XMP data model is called an XMP packet. Adding properties to a packet does not affect existing properties. Software to add or modify properties in an XMP packet should leave properties that are unknown to it untouched. For example, it is useful for recording the history of

150-605: A public patent license for the XMP. As of November 2016, Adobe continues to distribute these documents under the XMP Specification Public Patent License . XMP was first introduced by Adobe in April 2001 as part of the Adobe Acrobat 5.0 software product. Before that, it was called XAP (Extensible Authoring and Publishing) as internal code name. On June 21, 2004, Adobe announced its collaboration with

180-468: A resolution less than 800x800. Hello by Google's Picasa was a free computer program that enabled users to send images across the Internet and publish them to their blogs . It was similar to an instant messaging program because it allowed users to send text, but Hello focused on digital photographs . Users could opt to view the same pictures as their friends in real-time. One of the advantages claimed at

210-475: A resource as it passes through multiple processing steps, from being photographed, scanned , or authored as text, through photo editing steps (such as cropping or color adjustment), to assemble into a final document. XMP allows each software program or device along the workflow to add its own information to a digital resource, which carries its metadata along. The prerequisite is that all involved editors either actively support XMP, or at least do not delete it from

240-769: A typical edited JPEG file, XMP information is typically included alongside Exif and IPTC Information Interchange Model data. For more details, the XMP Specification, Part 3 Storage in Files listed below has details on embedding in specific file formats. The XMP Toolkit implements metadata handling in two libraries: Adobe provides the XMP Toolkit free of charge under a BSD license . The Toolkit includes specification and usage documents (PDFs), API documentation ( doxygen / javadoc ), C++ source code (XMPCore and XMPFiles) and Java source code (currently only XMPCore). XMPFiles

270-890: Is also integration with online photo printing services. Other simple editing features include adding text to the image. Picasa supports Google's WebP image format as well as the JPG format and most Raw image format (RAW files). A user can view and edit RAW files and save the finished edit (as JPG, or other forms) without any changes to the original RAW file. Picasa uses picasa.ini files to keep track of keywords for each image. In addition to this, Picasa attaches IPTC Information Interchange Model (IPTC) keyword data to JPEG files, but not to any other file format. Keywords attached to JPEG files in Picasa can be read by other image library software like Adobe Photoshop Album , Adobe Bridge , Adobe Photoshop Lightroom , digiKam , Aperture , and iPhoto . According to

300-769: Is an example XML document for serialized XMP metadata in a JPEG photo: This metadata describes various properties of the image like the creator tool, image dimension or a face region within the image. Embedding metadata in files allows easy sharing and transfer of files across products, vendors, platforms, without metadata getting lost. Embedding avoids a multitude of problems coming from proprietary vendor-specific metadata databases. XMP can be used in several file formats such as PDF , JPEG , JPEG 2000 , JPEG XR , JPEG XL , GIF , PNG , WebP , HTML , TIFF , Adobe Illustrator , PSD , MP3 , MP4 , Audio Video Interleave , WAV , RF64 , Audio Interchange File Format , PostScript , Encapsulated PostScript , and proposed for DjVu . In

330-509: Is currently available as a C++/Java implementation in Windows, Mac OS, Unix / Linux . The mainstream IPTC Information Interchange Model editing tools also support editing of XMP data. XMP is a registered trademark of Adobe Systems Incorporated. The XMP specification became an ISO standard and is not proprietary anymore. Initially, Adobe released source code for the XMP SDK under a license called

360-699: The ADOBE SYSTEMS INCORPORATED ;— OPEN SOURCE LICENSE . The compatibility of this license with the GNU General Public License has been questioned. The license is not listed on the list maintained by the Open Source Initiative and is different from the licenses for most of their open source software. On May 14, 2007, Adobe released the XMP Toolkit SDK under a standard BSD license. On August 28, 2008, Adobe posted

390-537: The Dublin Core Metadata Initiative , which include things like title, description, creator, and so on. The standard is designed to be extensible, allowing users to add their own custom types of metadata into the XMP data. XMP generally does not allow binary data types to be embedded. This means that any binary data one wants to carry in XMP, such as thumbnail images, must be encoded in some XML-friendly format, such as Base64 . XMP metadata can describe

420-501: The International Press Telecommunications Council . In July 2004, a working group led by Adobe Systems ' Gunar Penikis and IPTC's Michael Steidl was set up, and volunteers were recruited from AFP (Agence France-Presse) , Associated Press , ControlledVocabulary.com, IDEAlliance, Mainichi Shimbun , Reuters , and others, to develop the new schema. The "IPTC Core Schema for XMP" version 1.0 specification

450-725: The Linux operating system. It is not a native Linux program but an adapted Windows version that uses the Wine libraries. Google has announced that there will be no Linux version for 3.5. Currently, Google has only officially offered Picasa 3.0 Beta for Linux. On April 20, 2012, Google announced that they were deprecating Picasa for Linux and will no longer maintain it for Linux. To use latest version of Picasa on Linux, Linux users can use Wine and install Picasa for Windows. Linux users can use other programs to upload to Picasa Web Albums, including Shotwell and Digikam . On January 5, 2009, Google released

480-506: The "color" operator. Picasa has no separate view window. There is only an "edit view" with a viewing area. Fullscreen view is available in slideshow mode, by holding down the ctrl+alt keys while in "edit view", or by pressing the Alt Gr key. This feature is also available through the context menu of Windows Explorer, and provides a way to start the Picasa editor as well. In Picasa 2 and earlier versions, changes to pictures made in Picasa overwrite

510-542: The Picasa Readme, Picasa can parse Extensible Metadata Platform (XMP) data. However, it cannot search local files for existing XMP keywords. Picasa has a search bar that is always visible when viewing the library. Searches are live, so that displayed items are filtered as one types. The search bar will search filenames, captions, tags, folder names, and other metadata. Picasa also has an experimental feature that allows searching for images that contain certain colors with

540-569: The Places panel. The geotagging functionality is described in the Picasa User's Guide. Besides Google+ , Picasa also integrated with Picasa Web Albums , an image hosting and sharing web service. The service allowed users with a Google account to store and share their photos on the service. Users with a Google+ account received unlimited storage for photos of a resolution less than 2048x2048 pixels; all others received unlimited storage for photos of

570-1267: The closure of the Picasa Web Albums service on May 1, 2016. Google stated that the primary reason for retiring Picasa was that it wanted to focus its efforts "entirely on a single photos service" the cross-platform, web-based Google Photos . While support for the desktop version of Picasa ended, Google stated that users who downloaded the software, or who chose to download it prior to the March 15th deadline could still be able to use its functionality, albeit with no support from Google. Image organizer Image organizer software focuses on handling large numbers of images. In contrast to an image viewer , an image organizer can edit image tags and can often upload files to on-line hosting pages. Enterprises may use Digital Asset Management (DAM) solutions to manage larger and broader amounts of digital media. Some programs that come with desktop environments , such as gThumb (GNOME) and digiKam (KDE) were originally simple image viewers, and have evolved into image organizers. Many commercial image organizers offer both automatic and manual image organization features. A comparison of image viewers reveals that many free software packages are available that offer most of

600-471: The cloud-based Google Photos as its successor. Picasa Web Albums, a companion service, was closed on May 1, 2016. As of January 2015, the latest version of Picasa is 3.9, which supports Windows XP, Windows Vista, and Windows 7, and has Google+ integration for users of that service. Version 3.9 also removed integration with Picasa Web Albums for users of Google+. Since June 2006, Linux versions have become available as free downloads for most distributions of

630-473: The creation, processing and interchange of standardized and custom metadata for digital documents and data sets. XMP standardizes a data model, a serialization format and core properties for the definition and processing of extensible metadata. It also provides guidelines for embedding XMP information into popular image, video and document file formats, such as JPEG and PDF , without breaking their readability by applications that do not support XMP. Therefore,

660-660: The modified version is written in its place. On August 15, 2006, Google announced it had acquired Neven Vision, whose technology can be used to search for features within photos such as people or buildings. Google applied this technology for face recognition , and this functionality was launched on Picasa Web Albums on September 2, 2008. Neven Vision incorporates several patents specifically centered around face recognition from digital photo and video images. Since June 2007, Picasa can write geographic coordinates to Exif metadata, thus geotagging an image. Since version 3.5 of Picasa, geotagging may be done directly inside Picasa, in

690-732: The non-XMP metadata have to be reconciled with the XMP properties. Although metadata can alternatively be stored in a sidecar file , embedding metadata avoids problems that occur when metadata is stored separately. The XMP data model, serialization format and core properties is published by the International Organization for Standardization as ISO 16684-1:2012 standard. The defined XMP data model can be used to store any set of metadata properties. These can be simple name/value pairs, structured values or lists of values. The data can be nested as well. The XMP standard also defines particular namespaces for defined sets of core properties (e.g.

720-444: The organization features available in commercial software. There are several imminent advances anticipated in the image organization domain which may soon allow widespread automatic assignment of keywords or image clustering based on image content: In general, these methods either: Extensible Metadata Platform The Extensible Metadata Platform ( XMP ) is an ISO standard , originally created by Adobe Systems Inc. , for

750-404: The original file, but a backup version of the original is saved in a hidden folder named "Originals" in the same folder as the original picture ( .picasaoriginals on Mac OS X). In Picasa 3, changes to pictures made in Picasa are saved to a hidden file picasa.ini in the same folder as the original picture. This allows multiple edits to be performed without altering the original image. Viewing

780-463: The picture in Picasa or using the Picasa Photo Viewer will apply modifications on the fly, whereas viewing through other programs (such as Windows XP's Photo and Fax Viewer) will display the original image. Changes can also be made permanent using the "Save" function, where the original file is backed up in a hidden folder .picasaoriginals located in the same folder as the original picture and

810-576: The resource. The abstract XMP data model needs a concrete representation when it is stored or embedded into a file. As serialization format, a subset of the W3C RDF/XML syntax is most commonly used. It is a syntax to express a Resource Description Framework graph in XML. There are various equivalent ways to serialize the same XMP packet in RDF/XML. The most common metadata tags recorded in XMP data are those from

840-479: The website is that photos could be shared through firewalls. The service was canceled at the end of 2006, and users were instructed to try the Picasa "Blog This" functionality for uploading pictures to their blogs. According to the official website, the Hello project was shut down on May 15, 2008. On February 12, 2016, Google announced that the Picasa desktop application would be discontinued on March 15, 2016, followed by

870-493: Was provided by bundling the Windows version alongside the Wine compatibility layer. An iPhoto plugin and a standalone program for uploading photos were available for Mac OS X 10.4 and later. In July 2004, Google acquired Picasa from Lifescape and began offering it as freeware . The name was also registered by Google as an LLC . On February 12, 2016, Google announced it was discontinuing support for Picasa Desktop and Picasa Web Albums , effective March 15, 2016, and focusing on

900-505: Was released publicly on March 21, 2005. A set of custom panels for Adobe Photoshop CS can be downloaded from the IPTC. The package includes a User's Guide, example photos with embedded XMP information, the specification document, and an implementation guide for developers. The "User's Guide to the IPTC Core" goes into detail about how each of the fields should be used and is also available directly as
