[News] WP3 ongoing activities and AI's

[Danny R. Boxhoorn]

Current WP3 activities
----------------------
Implementation of
- complex Python queries.
  In particular logical operators (&, |) and a complex right hand side in
  comparison operations.
- explicit commit method for persistent classes.
  To allows a commit of Python objects together with all the objects that
  are referenced by that object.
- inline attributes.
  These give the database implementation a hint so it can exploit database
  specific optimisations.
- persistent source lists.
  To store e.g. sextractor results inside the database and use them from
  Python like any other persistent object.



Action Items from the QC meeting
--------------------------------

AI2. The action is on me to make a proposal. This proposal will also concern
     the `pipeline installation' part of AI9.
     Due 28/1
     
AI3. Agreed, but needs to be done.
     The (CVS) status of swarp and sextractor needs to be discussed with
     Emmanuel.
     Due 28/1

AI4. Done.


Action Items from the Leiden meeting
------------------------------------
AI: USM will play guinea-pig for the federated database- WFI data will 
    be used to populate a first version.

The first small steps have been taken to get this going.
Jan reported that the database setup in combination with the pipeline
works. This means it is possible to query data from the python prompt.
