If your Data Space was a Solar System, your personal Identity
would be the Sun. I say this because your Identity is the conduit
(access mechanism) to your data graph; the data you generate from
various application interaction activities such as: Blogging,
Bookmarking, Photo Sharing, Feed Aggregation etc.
Daniel
Lewis has just published a nice blog post titled: The Data Space Philosophy, that puts the
underlying Data Space concept in perspective.
The Linked Data Web is a Giant Global Graph of Data Spaces (meshes of data and identity
exposed by graphs connecting data and identity)
Data Portability ultimately depends on
platforms that provide unobtrusive generation of Linked Data (for
data referencing) alongside support for a plethora of industry
standard data formats -- which is what OpenLink Data Spaces has been about for a very
long time :-)
