Leibniz-Insitute for Astrophysics Potsdam, An der Sternwarte 16, 14482 Potsdam, Germany How to get there

We'll start our meeting in Schwarzschildhaus, seminar room at the ground floor. This is the building on the left side with the long roof. There's also a sign "Empfang" pointing there. Enter the buildung, walk straight ahead, turn left after the coffee machine. The room straight ahead is the seminar room. We may later switch to another room if there are WLAN troubles.

The bus 694 arrives every 20 - 40 minutes, stop "Sternwarte" is directly at the campus.

If you arrive by plane in Berlin, you can buy a Berlin ABC ticket (3.40 Euro single trip). This covers the Potsdam public transport as well. Check out the best connection via or

We plan to have dinner at an Indian restaurant in Babelsberg at 7 pm on Thursday:

Lunch is available at our small cantine, open from 11:30 - 14:00. They serve three different dishes each day for < 5 Euros. On Friday, we could also order Pizza, e.g. from Smileys. Their current lunch offer is here: Lunch offers (not in English, but with pictures! :-))

I'll provide some cookies for our breaks.

Topics to discuss / suggestions

  • Remaining Discussion points and TODOs from
  • review comments received on the dm list since Kristin issued the document
  • review/clarify the minutes of splinter meeting at ADASS. ( I have uploaded a corrected version on the wiki page)
  • define how to build a hierarchy of the metadata we want.
    Usually we have the terms MUST, SHOULD, MAY to define the standard description, but here we need to define different
    levels of description of the Provenance INFO, because some projects will want it to be compact and simple, and some
    others would like to be fully detailed, and the intermediate cases may also happen.
    Could we try to define 2 or 3 levels of templates for serialising the model?
  • Data Access Layer: What to keep in the current DM document and what to describe in a DAL document
    • TAP implementation status (Francois, Mireille)
  • Status of reference implementations
