Revision as of 14:02, 25 February 2009

The core developers of NeXML, CDAO, and PhyloWS met two weeks prior to the hackathon to better prepare the participating emerging standards for actual application at the hackathon.

Goals & Targets


  • Choose a very narrow limited set of goals, and include time to
    • evaluate carefully what we have done
    • extrapolate and plan for the big meeting when we have 20 people to keep busy
  • Need to discuss how to accommodate all the projects using php.

Target ideas:

  • Implement services that would allow Mesquite to query and retrieve character data and trees from TreeBase and from MorphBank.
  • Agreeing on how to implement semantic annotation of metadata types of the providers.
  • More fleshing out of PhyloWS specs.

Information to gather in advance:

  • Implementation details of the providers: which languages/libraries they use, what metadata they want to expose.

        • edit to add category for metadata types
        • edit to add questions about impementations (what is primary language for data processing, i.e., middleware in 3-tier scheme; what is the indexing methcanism for text searches; all custom code or uses toolbox or other code base)
        • send live survey to participants
      • solicit feedback on examples (Hilmar)
        • from TDWG colleagues on assigning specimens to collections
