Keepin’ Up With A LOD Of Changes

So, the other day I had a look at caching support in the Linked Open Data cloud and it turns out that there is a related discussion regarding caching on the ietf-http-wg@w3.org mailing list.

Then, there is another related update from Bill Roberts: Delivering Linked Data quickly with which I wholeheartedly agree.

To take the entire stuff a step further I tried to outline the overall problem in a short slide deck (best viewed full-screen ;)

My hunch is that 80% of the stuff is already out there available (such as Atom, Changeset vocabulary, voiD, etc.) and only minor pieces are missing. Next step would be to hammer out a simple demo and gather some more experiences with it. In case you are interested to chime in let me know :)

  1. a good start would be a common change notification protocol for Web of Data sources…we would like to raise this issue at the upcoming Linked Data Camp in Vienna

  2. @bhaslhofer – well, I’m not so sure if we need another proposal for a common change notification protocol (obviously, there are some on the table already [1]) or maybe you mean the discovery part? In this case it would be beneficial, I think, to use the Linked Data Camp to gather interest and work on a first proposal, yes ;)

    BTW, as a starting point I’ll create a stub for the dady Extension to voiD [1] (via purl.org) and happy to share with whoever is interested. Can you take over the local co-ordination and I’ll try to virtually participate via IRC in the respective session?

    Cheers,
    Michael

  3. agree…but it is important to agree on a common notification format for LOD sources. This should ideally be compiled from existing vocabularies (e.g., void + extensions). In our DSNotify approach, we introduce the notion of “change events” (with various subtypes)…An event reflects an atomic change within a data source….but this is all open for discussion.

    We will present a first proposal at the Linked Data Camp in Vienna
