Updated RDFT Specification

Excerpt: I've just uploaded the latest RDFT specification which incorporates the alterations I've been discussing over the past few days, including: Source Scope — a new scope that makes the NodePath apply only to the original source graph without the RDFS closure rules. Label Function — a new function that returns the current node's label. Data Model — some clarification of the data model. Subject Specifier — a node specifier that matches only resources that are the subject of a triple. Also uploaded is the latest version of the RDFT reference implementation: phpRDFT which implements all the features described in the latest specification.

New Version of phpRDFT

Excerpt: Along with the revised spec. is the revised version of phpRDFT which implements the spec changes plus one other big change - it now supports RAP 0.6 (the latest version).

RDF Templates

Excerpt: I posted this announcement to the www-rdf-interest mailing list just now: RDF Templates (RDFT) are an XML format for creating representations of RDF graphs. In a similar way to XSLT, RDF Templates define template rules with patterns which are matched against nodes. Template rules specify output actions and further node selections which trigger further template operation. However, instead of acting on an XML tree, RDFT acts upon an RDF graph. Nodes are specified using a 'nodepath’ syntax which defines conditional node/arc/node graph traversals. A macro definition facility is provided to reduce long nodepaths to easier to read strings. RDFT has been designed to parallel XSLT where sensible and anyone familiar with that language and with the principles of the RDF model should find it very easy to learn. RDFT solves a key …
