Pro Solutions Ltd. http://www.pro-solutions.com/ is pleased to
announce a Resource Description Framework (RDF)
Model & Syntax Specification (22-Feb-99) [1] API in Perl.
Please note that this is a beta release.
The API is implemented as a Perl module that works on top of the
RDF::Parser module. Both modules are available for download at
the Pro Solutions Warehouse at
RDF::Graph enables an application to browse a spanned RDF graph.
While browsing, the application can add and remove nodes or arcs.
The nodes in the graph correspond with URI addressable resources or
literal nodes (strings or well-formed xml markup). The arcs
correspond with predicates defined by RDF schemas. Finally, the
application can at any time export the graph into an RDF/XML
encoded document.
RDF::Graph also allows simple queries on the graph. For example, one
can query for all properties of a given resource or values of a given
property of a given resource. This querying satisfies also the closure
requirement for a query language i.e. running the query on one graph
will result in another graph.
The licensing policy for this module enables free non-commercial use.
The license text is available at the download address.
Feedback on the software is welcome at email address
