I just posted an update to my earlier work on creating an XML format for variable binding results from the RDF Data Access WG‘s SPARQL query language. This is not the final version, since I’m still considering two formats, one with XML schemas (RelaxNG and WXS) and one without. I’ve not been able to decide which one to go with although my preference is the non-schemas one as it reads cleaner to me. Writing XQueries for both forms didn’t help me much, they both are relatively the same to query.

The Julie IRC bot by Chris Schmidt was written using Redland’s Python bindings and relies on support for querying with RDQL. The main feature I like is its dynamic actions such as adding new commands as aliases for RDQL queries, loading and reloading data on demand from IRC. Julie comes with docs, source as well as a project description in DOAP (that URL is content-negotiated to HTML or RDF/XML)
