Using Freebase Gridworks to Create Linked Data [Jeni's Musings]
how to use Gridworks to generate linked data, using an example of local government spending data from Windsor and Maidenhead council... Gridworks is a simply amazing tool for data cleansing, analysis and, as we’ve seen, transformation. It’s set to become more so for our purposes in the near future, as it comes to support the mapping of names for things to URIs using configurable reconciliation services ... and the creation of RDF using a more intuitive and user-friendly approach than the templates that I’ve illustrated here - Jeni Tennison, 2010-08-22 (original post at 19:16)

Atom on the Web of Data: The Activity Streams Example
In order for semantic data to be used in a wider context, it must become less complicated while retaining its power... Even if some URIs don't change, there needs to be URIs for changing data-sets, and this precisely the kind of data that many applications and users need... What is needed is a way to incrementally add semantics to existing data streams, building on top of Atom directly. This is precisely the approach taken by the social web format Activity Streams, an extension to Atom to describe activities on social objects - by Harry Halpin and Chris Messina, 2010-05 (original post at 12:41)
