The term collection means that the resource is described as a group; its parts may be separately described and navigated. Dataset 2000-07-11 A dataset is information encoded in a defined structure (for example, lists, tables, and databases), intended to be useful for direct machine processing. Event 2000-07-11 An event is a non-persistent, time-based occurrence. Metadata for an event provides descriptive information that is the basis for discovery of the purpose, location, duration, responsible agents, and links to related events and resources. The resource of type event may not be retrievable if the described instantiation has expired or is yet to occur. Examples - exhibition, web-cast, conference, workshop, open-day, performance, battle, trial, wedding, tea-party, conflagration. Image 2000-07-11 An image is a primarily symbolic visual representation other than text. For example - images and photographs of physical objects, paintings, prints, drawings, other images and graphics, animations and moving pictures, film, diagrams, maps, musical notation. Note that image may include both electronic and physical representations. Interactive Resource 2000-07-11 An interactive resource is a resource which requires interaction from the user to be understood, executed, or experienced. For example - forms on web pages, applets, multimedia learning objects, chat services, virtual reality. Moving Image 2003-11-18 A series of visual representations that, when shown in succession, impart an impression of motion. Examples of moving images are: animations, movies, television programs, videos, zoetropes, or visual output from a simulation. Physical Object 2002-07-13 An inanimate, three-dimensional object or substance. For example -- a computer, the great pyramid, a sculpture. Note that digital representations of, or surrogates for, these things should use Image, Text or one of the other types. Service 2000-07-11 A service is a system that provides one or more functions of value to the end-user. Examples include: a photocopying service, a banking service, an authentication service, interlibrary loans, a Z39.50 or Web server. Software 2000-07-11 Software is a computer program in source or compiled form which may be available for installation non-transiently on another machine. For software which exists only to create an interactive environment, use interactive instead. Sound 2000-07-11 A sound is a resource whose content is primarily intended to be rendered as audio. For example - a music playback file format, an audio compact disc, and recorded speech or sounds. Still Image 2003-11-18 A static visual representation. Examples of still images are: paintings, drawings, graphic designs, plans and maps. Text 2000-07-11 A text is a resource whose content is primarily words for reading. For example - books, letters, dissertations, poems, newspapers, articles, archives of mailing lists. Note that facsimiles or images of texts are still of the genre text. 2000-07-11 The DCMI Type Vocabulary provides a general, cross-domain list of approved terms that may be used as values for the Resource Type element to identify the genre of a resource. Configuration Stable Based on the fact that a measurement is carried out by an agent using a specific metric according to one (or more) configurations over one (or more) datasets (atomic or composite) and produces a value (i.e. literal). The Configuration defines the polices with respect to a measurement is carried out. It defines polices about how to compare URIs and the configuration of an entity. http://www.ics.forth.gr/isl/VoIDWarehouse/VoID_Extension_Schema.owl Entity Configuration The notion of Configuration concerns issues that explain how the measurement was done. At this point, and for the requirements at hand, we need two subclasses: the first concerns the way URI equivalence is defined (see URIEquivalence class), while the second (the EntityConfiguration class) concerns how the entities of interest are defined. Regarding the latter the current modeling allows someone to specify the desired set of entities by providing a SPARQL query that returns them. Stable http://www.ics.forth.gr/isl/VoIDWarehouse/VoID_Extension_Schema.owl Measurement 1 1 http://www.ics.forth.gr/isl/VoIDWarehouse/VoID_Extension_Schema.owl The notion of Measurement is actually a specialization of dc:Event and therefore inherits the property date. A measurement is carried out by an agent using a specific metric according to one (or more) configurations over one (or more) datasets (atomic or composite) and produces a value (i.e. literal). Stable Metrics stable http://www.ics.forth.gr/isl/VoIDWarehouse/VoID_Extension_Schema.owl A metric is an individual with a URI and is defined by a resource (e.g. the DOI of the scientific paper that defined that metric). URI Equivalence The notion of Configuration concerns issues that explain how the measurement was done. At this point, and for the requirements at hand, we need two subclasses: the first concerns the way URI equivalence is defined (see URIEquivalence class), while the second (the EntityConfiguration class) concerns how the entities of interest are defined.

Entries are declared using RDF Schema language to support RDF applications. The Schema will be updated according to dc-usage decisions. Collection 2000-07-11 A collection is an aggregation of items.
