I recently began particpating in the W3C eGov Interest Group and learned about the concept or practice the connecting data to other data avialable on the Web. It is a concept that Tim Berners-Lee calls “linked data“. The potential is huge. I don’t fully understand the details, but I was pointed to following presentation by Tim Berners-Lee at the TED Conference. The video introduces the concept and the underlying potential.
