91 <rdfs:Class rdf:ID = "Collection">
92 <rdfs:label>Collection</rdfs:label>
93 <rdfs:comment>A collection is an aggregation of items. The term collection
94 means that the resource is described as a group; its parts may be
95 separately described and navigated.</rdfs:comment>

100 <rdfs:Class rdf:ID = "Dataset">
101 <rdfs:label>Dataset</rdfs:label>
102 <rdfs:comment>A dataset is information encoded in a defined structure (for
103 example, lists, tables, and databases), intended to be useful for direct
104 machine processing. </rdfs:comment>

109 <rdfs:Class rdf:ID = "Event">
110 <rdfs:label>Event</rdfs:label>
111 <rdfs:comment>An event is a non-persistent, time-based
112 occurrence. Metadata for an event provides descriptive information
113 that is the basis for discovery of the purpose, location, duration,
114 responsible agents, and links to related events and resources. The
115 resource of type event may not be retrievable if the described
116 instantiation has expired or is yet to occur. Examples - exhibition,
117 web-cast, conference, workshop, open-day, performance, battle, trial,
118 wedding, tea-party, conflagration. </rdfs:comment>

124 <rdfs:label>Image</rdfs:label>
125 <rdfs:comment>An image is a primarily symbolic visual representation
126 other than text. For example - images and photographs of physical
127 objects, paintings, prints, drawings, other images and graphics,
128 animations and moving pictures, film, diagrams, maps, musical
129 notation. Note that image may include both electronic and physical
130 representations.</rdfs:comment>

136 <rdfs:label>Interactive Resource</rdfs:label>
137 <rdfs:comment>An interactive resource is a resource which requires
138 interaction from the user to be understood, executed, or
139 experienced. For example - forms on web pages, applets, multimedia
140 learning objects, chat services, virtual reality. </rdfs:comment>

146 <rdfs:label>Service</rdfs:label>
147 <rdfs:comment>A service is a system that provides one or more
148 functions of value to the end-user. Examples include: a photocopying
149 service, a banking service, an authentication service, interlibrary
150 loans, a Z39.50 or Web server. </rdfs:comment>

156 <rdfs:label>Software</rdfs:label>
157 <rdfs:comment>a computer program in source or compiled form which
158 may be available for installation non-transiently on another
159 machine. For software which exists only to create an interactive
160 environment, use interactive instead. </rdfs:comment>

165 <rdfs:Class rdf:ID = "Sound">
166 <rdfs:label>Sound</rdfs:label>
167 <rdfs:comment>A sound is a resource whose content is primarily intended to be
168 rendered as audio. For example - a music playback file format, an audio
169 compact disc, and recorded speech or sounds. </rdfs:comment>

174 <rdfs:Class rdf:ID = "Text">
175 <rdfs:label>Text</rdfs:label>
176 <rdfs:comment>A text is a resource whose content is primarily words
177 for reading. For example - books, letters, dissertations, poems,
178 newspapers, articles, archives of mailing lists. Note that facsimiles
179 or images of texts are still of the genre text. </rdfs:comment>
