Practical RDF Shelley Powers
Publisher: O'Reilly Media

The Resource Description Framework (RDF) is a framework for representing information in the Web. If practical, we should be looking at backporting features from Perl 6 to Perl 5, not just because it has an awesome feature set, but to help ease transition. Leigh Dodds presents the first of a multipart tutorial on SPARQL, a query language for RDF and the Semantic Web, which may also play a role in Web 2.0 apps and services. While there is potential to use more native datatypes, the practical issues of repeatable properties, blank nodes, etc mean that a 1:1 mapping isn't feasible. VoID (from "Vocabulary of Interlinked Datasets") is an RDF based schema to describe linked datasets. €� Publishing XML files using XSLT. With VoID the discovery and usage of linked datasets can be performed both effectively and efficiently. In cases where this is not practical, the index scheme should only have full indices; i.e., each key holds all columns of the primary key of the quad. I helped TimBL refine Delta: an ontology for the distribution of differences between RDF graphs a bit, and there's working code in cwm. Managing Digital Humanities Projects. €� TEI for linking text and facsimiles. RDF has a simple data model that is easy Yeah, I agree that the resource-centric (or node-centric) view is more practical, and that's the direction we took in Needle, too. And the availability of several SPARQL query engines means that this exploration can be practical rather than theoretical. This is what I came up with: ~~~~.

MTMH 2012 was a joint hackathon between the people working on p5-mop (a project to get a Moose-lite metaobject system into the Perl 5 core) and the Perl RDF toolkit, with a few Rakudo people thrown in too, ostensibly for convergence between the p5-mop and Perl 6 metaobject systems when possible. I've been mulling over this alternate way of thinking about RDF, one that is resource-oriented rather than triple-oriented. But what if you're a lot more interested in Web 2.0, which is practical and real, than in the Semantic Web, about which opinions vary widely? RDF is defined as an abstract data model, plus a collection of practical notations for exchanging RDF descriptions (eg. €� Practical RDF modelling and conversion. €� RDF querying and visualization. But I haven't really managed to use it in practical settings.
