---++ Materials and notes from the work group and plenary sessions

---+++ Joint session with DM group
---++++ Tools for UCD1+
There is a set of [[http://cdsweb.u-strasbg.fr/UCD/tools.htx][simple tools for UCD1+]], also available as [[http://cdsweb.u-strasbg.fr/cdsws/ucdClient.gml][Web services for UCD1+]]

---++++ UCDs for the SED data model
JCM presented the list of new proposed UCDs since Pune (some already adopted):

   * phys.energyDensity - useful for extragalactic, CMB
   * stat.fill  - Filling factor
   * arith.log (rejected at Pune, handle with units)
   * spect.radioVeloc and spect.optVeloc
   * curation-type stuff
   * src.net, src.total, src.background
   * instr.beam (already there)
   * stat.error.sys
   * change def. of time.expo -> exposure length

---++++ UCDs for Planetology
Work on this topic started after [[http://www.france-vo.org/twiki/bin/view/ASOVFrance/Tutoriel2004][french VO tutorial]] (oct 2004):
   * Planetary Data System -> VO
   * Space Time Coordinates: changes are needed

   * VO planeto activities:
      * [[http://portail.imcce.fr/fr/expert/ssvo/wgovp/propucd.html][13 new UCDs and 8 modifications]]
      * provide VOTable output of planetary data
      * Data Model
      * Extension of activities, involvement of community, and link with <nop>EuroPlanet

   * Expected results for first VO-compatible applications, end of 2005

---+++++  Discussion: 
  Pedro Osuna: discuss with ESA (about collaboration with NASA).
  Andy Lawrence: AstroGrid covers solar data - are there UCDs there

---+++ General DM-UCD discussion:
   * GL asks to clarify difference between UCD and utypes ?
  utypes = pointers for serialization of DMs
  ucd = can be simpler, able to generalize with the 1st word: UCD = one-word data model (when we don't need to go into the details)

   * On the question of merging UCD (or semantics) in the DM (or modelling) activity ->  JCM: good idea to keep the vocabulary separate from the DM structure for the moment

   * APM proposal:
      * keep WG
      * add 'semantics' to UCD in the WG's name
      * have standard list of words (stabilisation) before summer 2005
      * don't try to do an ontology immediately

---+++ Joint session with VOEvent
AA summarizes result of discussions on UCD that took place during yesterday's [[InterOpMay2005VOEvent][VOEvent session]] 

---++++ Discussion on VOEvent
   * Allow a 6 months period for the definition of a list of standard expressions used by the VOEvent producers.
   * Discuss possible changes to the schema about the content of the &lt;Hypothesis&gt; schema within the VOEvent-core mailing list after this meeting.
 
---+++ UCD board creation:
   * Scientific board:
      * APM sends a message: those answering within 10 days will be part of the scientific board
      * The board discusses on words evolution/modifications/suppression/addition
      * The first board leader will be the leader of the WG. Later on, the board will choose a scientific leader. The WG leader can take final decisions.
      * End of may: first board is composed, ready to work
      * Work in june on list of words
      * Then, move list of words to PR

   * Technical board:
      * In charge of building software and tools
      * Creation process same as sci. board
