The document discusses the BBC's efforts to publish its programmes and music content on the Linked Open Data cloud. It describes how the BBC has created web pages and RDF representations for individual programmes, artists, albums, and other entities. These efforts allow the BBC content to be interconnected with other datasets on the web. Technical details are provided about the BBC's use of ontologies, URIs, and a model-view-controller framework to support these Linked Data initiatives. Future work is discussed, such as improving music recommendations and publishing SPARQL endpoints.

Web 2.0 principles are:
“it’s the data, stupid” *
(formally “data is the Intel Inside”)
small pieces loosely joined*
persistent IDs
if you can’t point to it it’s not a web 2.0 citizen
“the age of point-at-things” **

To SPARQL or not to SPARQL?
we have to consider scale and reliability
data replication
because we shouldn’t serve sparql off the main database
hard to keep things dry
don’t repeat yourself - maintain SPARQL mapping and templates
just crawl rdf?
