0.6.1 bug fix release now available

A maintenance release, version 0.6.1 was released today on sourceforge [1]. There were a few coding bugs in the 0.6.0 release relating to the namespace match method "all", the rdf rule order was not being imported from the configuration properly resulting in queries which relied on more than one rule not getting any results back, and included static RDF/XML sections were not being included. There was also a fix related to default providers that eliminates duplicate queries for namespaces where a namespace was assigned to a default provider for a query that allowed default providers.

The configuration files have also been updated, although people using the live configuration method (the default) would have received the configuration changes already. Some performance improvements related to logging have also been made that in some circumstances will dramatically improve the performance of the package, although the majority of the overall request latency is still related to internet latency related to the SPARQL queries.

From this version on, I will also be releasing MD5 hashes for each of the downloaded files so people can check that their downloaded file matches the release on sourceforge.

Version 0.6.0 of the Bio2RDF server software released

The next version of the Bio2RDF software, version 0.6.0 was released today on sourceforge [1]

It has some major feature additions over the previous version, with the highlights being an RDF based configuration, the ability to update the configuration while the server is running, and support for sophisticated profiles so that users can pick and choose sources without having to change the basic configuration sources that are shared between different users. If users want to add or subtract from the base configuration they can create a small RDF file on their server and use that file to pick which sources they want to use and which queries they want to be able to execute.

If anyone wants to check out the example [2] and use it as a guide to mock up some SPARQL queries or definitions for endpoints that go with the queries it would be great to see what other resources we can combine into the global Bio2RDF configuration. If you need pointers in how to get your own configuration working feel free to ask me.
