Thanks a lot Henry for your advice and pointers to some great resources.
I will take a dive into Scala resources and try it out.
My real interest is in implementing a pluggable verified digital identity
framework to be integrated to existing web systems. Clerezza and LDP
projects are great places to achieve my objectives. However I'm not an
expert in Scala which seems to be a bit of a barrier to entry for LDP
project. Nevertheless I will start learning Scala as it seems to be a great
language to expand my programming skills.
I will further read about WebID and it's use cases in distributed social
networking, digital identity services, and semantic analysis and entity
disambiguation areas.

I would also like to get some expert opinions on how WebID can help in
semantic enhancements space. Specifically how it can help in
entity-disambiguation. It will be great to get some ideas on how to achieve
entity disambiguation using WebID and FOAF in general.

Thanks,
Dileepa
