Re: LD and Redundancy

I tend to agree with Joachim - we will see more data publication and at least in this phase will see plenty of institutions coining their own URIs. However, I also believe that the web tends towards less duplication (this isn't anything close to no duplication, just less duplication than we would have otherwise). 

We are already seeing that established URIs will be used where they exist (e.g. for LCSH) - and I guess we can expect to see more of these.

That said, I think aggregations are a good thing (and inevitable) - and the more identifiers are shared, and the more people make sameas and similar statements, the easier aggregation will become.

In terms of what we should be doing now? I'd say:

Encourage re-use of URIs (ideally this would be baked into record creation in libraries, but that's a whole other ball game)
Encourage sameas statements where new URIs have been coined (and appropriate)
Start looking at how existing linked data representations of bibliographic data can be crawled and aggregated and see what works and what doesn't

I'm sure there is other stuff, but those are the ones that spring to mind first

The work of the JISC 'RDTF' (Resource Discovery Task Force) in the UK is looking at the strategy of 'publish' and 'aggregate' - although this doesn't dictate the use of Linked Data or RDF, many of the project falling into this area are adopting that approach, so hopefully we will see a good exploration of some of the issues from this area soon. See http://rdtf.mimas.ac.uk/ for more information on this.

These all require additional work on the part of systems and people, which will rarely be expended, with the result that link potency will (continue to) be diluted to insignificance.
