I strongly urge you to listen to this podcast interview that I had with
Jon Udell about this matter last year . Key points:
This is about Personal Data Spaces. These Data Spaces are comprised of:
1. Strong Identity -- delivered by WebID
2. Structured Profiles -- delivered by FOAF and/or XRDS (via hammer stack)
3. Structured Expression of Needs and Offers -- delivered via
4. Structured Linked Data -- delivered by HTTP based Linked Data
(covers: AddressBooks, Calendars, Bookmarks, Feeds, Briefcase (File
Server), Wikis, Photo Galleries, Discussions, and much more..
Personal Data Spaces are nodes on the truly distributed and open social web.

The concept of Personal Data Spaces has developed many labels over the
years, the most recent being the Personal Data Locker.
The key thing is this, items #1-4 above, delivered in a loosely coupled
fashion is basically what the social web we all seek is about. We just
need to leverage Web Architecture (via Hammer Stack, Linked Data etc..)
so that a federated read-write web materializes, sooner rather than later.
