---++ Follow-up: Participant Feedback and Requests

The section gathers partipant requests. It is intended to provide both modellers and developpers with inputs on missing, misleading or failing features.
   * Any contribution is welcome.
   * Those who have trouble with editing the Wiki can send an Email either to IVOA.MarkCresitelloDittmar or IVOA.LaurentMichel
   * Please, sign your contribution so that we can get in touch with you for any further precision.

   * During our exercise trying to map the prototype Source model to Gaia data results, we discover some model elements that were missing or not clear. If any of these are present, we couldn't figure out where:
      * Proper Motion (in this case, 2 values, RA PM and Dec PM)
      * Radial velocity
      * Position error (in this case, 2 values, RA Err and Dec Err)
   * Documentation seemed missed from most model elements.
   * When model elements are Quantities, units can be specified in VODML. How does this relate to the units on the FIELDs? Is it duplication, or does it represent a different flavor of unit, or can/should the VODML unit be left blank in cases where a FIELD specifies it?

---++ Wednesday May 30 -- 14:00 to 17:30

These sessions are intended to help data modellers to learn to use the available tools in order to describe their own models using VO-DML. This is a hands-on workshop/hackathon style event and *not* a normal speaker-audience-dicussion session.

If this doesn't sound like something you are ready to do or are interested in, then please don't feel guilty about taking the afternoon off to see more of Victoria, go whale-watching, etc
---++ What is this all about?

VO-DML is the Virtual Observatory Data Modelling Language : <a href="http://www.ivoa.net/documents/VODML/index.html" title="VO-DML-1.0">http://www.ivoa.net/documents/VODML/index.html</a>

The purpose of this session is 2 folds
   * Giving VO people the opportunity of doing a concrete job with VO-DML and getting answers to any questions: 
      * How to build a model
      * How to reuse a model
      * How to annotate existing data
      * How to annotate dynamically generated data
      * How to parse annotated VOTables
   * Checking that the current VO-DML workflow fulfill the expectations of the community 
      * Gain in term of interoperability
      * Curtation and developement effort
      * Sustainability
Participants can bring their own models, VOTables or even code.

---++ Project Pitch

   * Gregory: Existing data from Wise, annotate with example data models.
   * Olga: annotating NED images. Extend metadata for Cubes. List of minimal requirements. (Need anybody with solid knowledge about cubes)
   * Mireille: vodml-ize CharDM
   * Tim: Interop of WCS and Transform between GWCS and . Need a plan! Ideally STC2
   * Pat: CAOM2 in VODML. Unit tests for models. Show you how to Continuous Integration.
   * Tom: Exploring VODML annotations for Vizier Catalogs. (Need Vizier experts).
   * Baptiste: STC2 with XML schemata for inclusion in VOEvent.
   * Carlos: SimDM in VODML.
   * Marco: how to build a model, from idea to VODML-XML.
   * Omar: Explore JSON Serialization, Requirements on Data Providers Tools. SVO Photometry Filter Service annotations.
   * Dave: Mapping tool, what I need to do to make it automatic
   *
