If there are anybody on this frequency able to make informed status reports on the progress of the implementations, then I'd love to have a small report. Fx:  * API completeness  * Onto support  * XML Query support  * User Search Lang. support  * Roadmap to feature completeness (of full Xesam 1.0 support) </blockquote></div> Ok, might as well give my own perception of our situation then :-) My own limited knowledge will hopefully provoke someone to elaborate... Beagle:  * API completeness: Complete  * Onto support: Support for a limited subset of the onto. Most common fields can be expected to work.  * XML Query support: Check  * User Search Lang. support: Actually just use the standard Beagle search language, which is close enough to the Xesam USL so that users might never notice the difference  * Roadmap: Anticipate Xesam developments and quality of the API. If deemed good move the xesam-adaptor into Beagle's core Pinot:  * API completeness: No Xesam API yet  * Onto support: None  * XML Query support: Check  * User Search Lang. support: Check  * Roadmap: ? Strigi:  * API completeness: The code seems to be there, but I have not been succesful using it yet...  * Onto support: I see the ontology in the Strigi source tree but I don't know if it is used  * XML Query support: Check (sharing code with Pinot)  * User Search Lang. support: Check (sharing code with Pinot)  * Roadmap: Bug fixes Tracker:  * API completeness: Being written as we speak/email  * Onto support: Also in progress at this moment  * XML Query support: Supports RDF-query which is very close to Xesam's QL, porting should be swift and without mercy ;-)  * User Search Lang. support: No  * Roadmap: Support Xesam for next major release. Lots of people are working on this Cheers, Mikkel
