Notes de l'éditeur
- Apart from social media sites adding rel=me links to their profile pages and individuals marking up blogs with the elsewhere on the web patternA number of specialist sites are now listing peoples Distributed Identities to help project web personsa and also mark services that they aggregating information from

- There are many software libraries that can parser microformatsUfXtract is a c sharp parser I wrote an I also host a web based API at ufxtract.comThe example URL in the slide shows how call for JSON respentation of the hCard on the slideshare profile we where just looking at
- For sites which are more about interaction outside of work you could be looking at a smaller subset.Dropping job title, company and the bio
- This is the last of the demos from the Ident Engine siteThe librarySearches for identities using the social graph APIIt then looks through the data overlays for information it can retrieve and builds a lifestream for that individualSo it has returned tweets, bookmarks and photo’s from flickrAll of this from entering a single URL
