Reto, Sorry for taking so *long* to reply!
I do think there is a good intersection between Semantic Web and distributed OSGi. Two reasons that come to mind include scale and "cloud". As you know OWL/RDFS reasoning/querying is an expensive function. When the knowledgebase grows to any substantial size, performance becomes unacceptable. Although scale has improved, it remains a challenge. As for "cloud", I thought "SOA" was an overloaded term, but "cloud" is much worse! Nevertheless, the way we design, build, deploy and maintain software systems - I believe - will become increasingly modular and distributed. As data is distributed in Hadoop, software modules will be similarly distributed. I could be wrong! :-) So my "hypothesis" is that a distributed OSGi services "fabric" will align with the "modular and distributed" "cloud" concept; and such a fabric can parallelize OWL/RDFS reasoning/querying functions. I'm wondering if Clerezza can built in such a fashion. I'm sure it can, but I also know it's easier said than done! In the short term, I think I'll focus on learning and using Clerezza - as is. :-) Thoughts? Thank you!
