- Hyperdata
Hyperdata [ [http://novaspivack.typepad.com/nova_spivacks_weblog/2007/09/hyperdata.html The Semantic Web, Collective Intelligence and Hyperdata] ] -- indicates data linked to other data in other places. This forms a web of data, evolving from the "data on the Web" that is not inter-related (or at least, not linked).
Like
metadata , hyperdata express semantics [ [http://www.semanticfocus.com/blog/entry/title/metadata-or-hyperdata-link-or-thread-what-is-a-web-of-data/ What is a Web of Data] ] .Metadata indicates local facts of data on either the conceptual essence (e.g., Web 2.0-style tags) or the semantics of display (e.g., XHTML tags). These facts are locally consistent, and are immutable against the variation of the external links. In contrast, hyperdata expresses semantics of local data in relation with other data. Effectively, hyperdata indicates where a local data item sits within a broader network of data items.A Hyperdata Browser (also called a Semantic
Web browser ), is abrowser used tonavigate theSemantic Web .Semantic Web architecture does not necessarily involve typical formats likeHTML , whichHTML browsers rely on. A Hyperdata Browser specifically requestsRDF data fromWeb servers , often throughcontent negotiation or "conneg" starting from the sameURL as the traditional Web browser; the Web server may immediately return the requested RDF, or it may deliver a redirection to a new URI where the RDF may actually be found. The RDF data will generally describe theresource represented by the originally requestedURI . The Hyperdata browser then renders the information received as anHTML page that containshyperlinks for users to navigate to indicated resources.Related keywords
