Resource Description
Framework (RDF) [top]
Australian Government Architecture Reference Models Version 3.0
A family of specifications for a metadata model. The RDF family of
specifications is maintained by the World Wide Web Consortium (W3C). The
RDF metadata model is based upon the idea of making statements about
resources in the form of a subject-predicate-object expression and is a major
component in what is proposed by the W3C’s Semantic Web activity: an
evolutionary stage of the World Wide Web in which automated software can
store, exchange and utilise metadata about the vast resources of the Web, in
turn enabling users to deal with those resources with greater efficiency and
certainty. RDF’s simple data model and ability to model disparate, abstract
concepts has also led to its increasing use in knowledge management
applications unrelated to Semantic Web activity.
Result Set [top] A Query Point provides the result set for an Exchange Package. (DRM usage)
In SQL, a result set is a set of rows from a database, as well as metainformation
about the query such as number of results returned and the column
