oh, but you mention SPARQL queries, so doesn't that mean that we'd need full resource/RDF/URIs approach at least internally at the Beeb? or at least the capability and internal structure and data model in place internally to publish our data out to the world at a SPARQL end-point?
to really offer SPARQL GUIDs are probably neither here nor there, but we'd need to do pretty well with URIs, no? personally, i liked the suggestion earlier to use dBpedia.org URIs as a starter lingua franca of URIs... clearly that wouldn't be relevant for IDing many of the resources pertinent to the editing suite, but even there it'd be relevant for some (people the video clip was about, etc) best-- --cs -----Original Message----- From: Chris Sizemore Sent: Wed 3/5/2008 6:38 AM To: backstage@lists.bbc.co.uk; backstage@lists.bbc.co.uk Subject: RE: [backstage] What would you love to see coming out of BBC Vision in the near future? wow, now that's a cool idea. any BBC DMI guys lurking on the list? -----Original Message----- From: [EMAIL PROTECTED] on behalf of Michela Ledwidge Sent: Wed 3/5/2008 1:08 AM To: backstage@lists.bbc.co.uk Subject: Re: [backstage] What would you love to see coming out of BBC Vision in the near future? BBC Vision edit log data would be good. Lots of useful meta-data there. As for getting the meaning out there. GUIDs might be less important than being able to perform semantic queries on whatever naming conventions exist already around the Beeb. e.g. creating a pool of edit log data and opening it up for SPARQL queries would perhaps be very useful. Not necessarily that useful having a particular tape ID as a GUID The ability to run queries over film/video logs, typically only viewed by editors, would no doubt reveal gems for repurposing and redistribution, let along allowing the Beeb to track and re-use source material better.
