On November 8th 2007 CRIG had a series of teleconference chats. The intention of these chats was to begin a discussion between members on how repositories might be improved (bluesky thinking). These chats are podcasted below with a mindmap of the chats as they unfolded. We ask that you take time to blog about one of the podcasts to help spread the word on the importance of repository improvement.

Our organising principle / metaphor for these chats has been "peeling the layers of the repository onion" or rather if a repository was a car how could we improve it? Starting under the hood / bonnet there are the separate pieces that make up the various engine parts like clutch, combustion chamber, and exhaust (repository APIs: search, get, put). There is then what you put in the car to make it run, be that petrol, bio-fuel or electricity (repository objects: IMS-CP, MPEG DIDL, DC, etc). There is then access to the car; how do we know who we want to drive the car and what are the methods of access: keys, driver's license (repository authorisation and identifications). The car must be able to accommodate various users like families, workers and salesmen (scenarios: researcher, teaching/learning, administrative). The "repository car" must be able drive in its environment on the left and/or right hand side of the road maneuvering various obstacles like roads, hills, dirt, snow (repository ecology). And finally, the car must be interoperable with other services like parking lots, bridges and ferry boats (other services: VLEs, OPACs and Interfacing Tools). Accordingly, as we peel the layers off of our repository car we begin to see how each must be innovative in their own application but also conform to the onion as a whole. <-- think we could get McLaren as a sponsor? ;)

Search in Repositories

Comments: the discussion on federated search seems to have got split between SPARQL node and the harvesting node. Specifically, SPARQL can join across records. I think the point was that joining across records is difficult in federated search (so perhaps we should be excluding it from our thinking...)?
