RDF and free software hacking

Portable.NET 0.5.10 released 2003-07-26. No .debs yet.

Raptor RDF Parser Toolkit 0.9.11 released. This version passes all the RDF Core tests as well as gaining an RSS “tag soup” parser for sloppy RSS XML. It’ll go gold as 1.0 assuming no big problems are found.

FOAF grouping by Bill Kearney using the new foaf:member added to the FOAF schema yesterday.

I’ve been collecting a list of various Semantic Web themed weblogs around, or those that address these issues now and then. It feels like a good time to share this. The ordering here is vaguely by family or project name.

Semantic Weblogs

RDF, FOAF, RSS 1.0 articles this week by me to www-rdf-interest

Tracking provenance of RDF data (IBM developerWorks XML Watch) by Edd Dumbill. Outlines why you want to know who said something when you aggregate RDF data (which you want to do a lot) and then demonstrates it in python using my Redland RDF library and the new contexts feature. He also says some very nice things about Redland. Thanks a lot Edd!

Missing isn’t broken: data validation and freedom on the Semantic Web by Dan Brickley. A good outline of one part of the webiness of RDF - missing parts do not break things. This seems to be one of the sticking points for people familiar with XML apart from taking RDF’s XML syntax to be equivalent to RDF’s model. I’ve spoken [...]

Parsing RDF with python from Bill Kearney showing a small bit of code fragment (via Dan Connolly) that implements the question Bill had in his original RDF examples: who is secretly stalking Bob?. It’s done using Daniel Krech’s all-python rdflib in a hardly 20 lines of code.

Processing FOAF with C# by Edd Dumbill. This is actual two mini-reports under the one title. The first is on the C# language and it’s application, here using Drive. The second and more substantial is his conclusion that using an RDF parser with FOAF (or RDF) is the easy choice.

FOAF and Web of Trust on Practical RDF by Shelley Powers. Also I wanna hold your hand on her other blog more about putting your personal information online.
