Redland Porting Hints

Thursday, July 29th, 2004

Just dashed off some quick Porting Hints for Redland, Raptor and Rasqal mostly for win32, based on what I’ve heard from various people and described in email from time to time. I’m pretty confident Raptor is straightforward, quite confident about Rasqal (no requirements but Raptor) but then Redland and the language bindings can take a lot of optional libraries (SleepycatDB/BDB, MySQL, …).

Parsing 8G of RDF/XML

Wednesday, July 28th, 2004

Last week the UniProt in RDF Format was announced by Eric Jain. This includes a 700Mb gzipped RDF/XML file in the data area. That’s 8369854785 bytes of RDF/XML. So, of course I had to throw my Raptor parser at it to see if it’d survive. Round 1, it died with this error:

Rearranging Redland packages

Friday, July 16th, 2004

This is a summary of some thoughts I’ve been having about rearranging the Redland packages after some poking by Edd Dumbill based on an email to redland-dev. The problem I’ve been having is that the (7 or 8) language APIs are changing at a faster rate than the core C redland librdf. This is a good thing of course, but it [...]
