 In the current page we refer to several images  which are open-annotation representations of DASISH xml examples. The reader is encouraged to consult these images while reading the text. The dashed ovals in the images depict unresolvable uris, whereas the ovals with solid contours depict resolvable uris.

+A cached representation of a source (as {{{oa:SpecificResource}}}) is referred via the source's state, see the figure above. The properties {{{oa:hasState}}} and {{{oa:cachedSource}}} are used. The metadata of the cached representation are presented via dc-properties and {{{dctypes}}}:

+
+* {{{tool}}} is presented as  [http://dublincore.org/documents/2012/06/14/dcmi-terms/?v=elements#elements-publisher |  {{{dc:publisher}}}],
+
+* {{{type}}} is presented as {{{dc:description}}}; note that {{{dc:type}}} cannot be used here because its value must (recommended) be from the DCMI Type Vocabulary; therefore, e.g. "screenshot" would not be a good value here.
+
+Moreover, a cached representation must have one of the {{{dctypes}}} as {{{rdf:type}}}, and it must be compliant with {{{dc:format}}} value. For instance, if {{{dc:format}}} is {{{"image/png"}}} then the corresponding {{{rdf:type}}} must be {{{dctypes:Image}}}.
