Re: Silk - Link Discovery Framework Version 2.4 release

Thanks Misha

I agree

I took a screenshot, attached, for future reference.

Since SILK according to the information provided in the link was
released last year, and LOD2 funding started after the release date, I
am just asking for a clarification (or clearer project information?).

It is important for these clarifications to be made in public fora,
and that people concerned are kept in the loop, for the benefit for
everyone involved

Look forward to learn more about SILK and LOD2!

Cheers
