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 http://www.pro-solutions.com/download MAIN FEATURES 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 warehouse@pro-solutions.com References [1] http://www.w3.org/TR/1999/REC-rdf-syntax-19990222/ -- Janne Saarela <js@pro-solutions.com> Pro Solutions Ltd.
