Status:

WG/Apps (TD/RD)

Status:

WG/DAL (MM/JD)

Status:
Issues: (from Feb telecon - needs update)
  • Service Weather report on DAL protocol "SHOULD"s: collected data providers view, need to report (here, e.g.)
    • From discussion with data providers (just after the College Park interop) the view that turned out is that there's not really the need to act upon the SHOULD-s validation warnings. This is because those SHOULDs can be related to information good to have but maybe not available (especially for old datasets), or because it brings in a feature that is not felt important to the provider. In the end the feeling is that working on those warnings as something to clean from the operational point of view could not be the right approach and modifying existing standards o demote shoulds looks not a good idea. This does not mean validation is not useful, but feature-usage driven checks can show a different picture. The Service Weather report outcome looks like a place to start a DAL/Ops discussion for a report that looks more like a Registry/Ops driven one.
  • polygon CCW: modelling seems solved (errata in other WGs), data providers side, how to proceed?
    • initial DAL email didn'twork, turned out in a region discussion turmoil

WG/DM (MCD/LM)

Status:
  • Errata:
    • ObsCore-1.1 and STC-1.33 pages created and discussed.. ready for TCG vote.
  • Coords:
    • Updated document with variuos feedback items; delivered to WG and doc repository (Mar 21)
    • Vocabularies installed to semantics workspace.. Semantics group working discussion/review of content with TDIG/SSIG
    • Example serializations being updated/expanded to newest content.
  • Transform:
    • Extensive review/iteration with author list to cover all the requirements.
    • Folded in the enhanced requirements descriptions noted for Coords model.
    • 'Final' version delivered to author list (Apr); expect this to go to WG and repository in the next couple weeks.
  • Meas:
    • Updated model content to current Coords model state
    • Simplified the levels of abstraction to reduce #boxes
    • Working document: have general structure, need to add descriptive content to model and process (~1wk job) (by end April).
  • Prov:
    • The situation does not allow to define a clear timeline
    • A compromise model has been proposed by the chair(s) in order to reach a consensus among the authors
    • A PR#2 document based on that compromise is still discussed.
    • Our goal remain to open the REC page as soon as possible.
  • SSDL-2.0
    • WG response to Feb. drop has been quiet.
    • working vo-dml processing/validation using current scripts
    • ready for PR/RFC?
  • Time Domain
    • promised new Mapping serializations of all their example files; STILL NOT DONE (resource issue)

Roadmap:

  • TIMESYS:
    • Integrated in VOTable1.4
    • GAVO and VizieR have been collecting metadata for time, and would be ready to use TIMESYS if a Rec.
    • How to make use of TIMESYS? bring to common frame? Need to developed code to do so.
  • Time-MOC:
    • Several hundred T-MOCs already produced by VizieR and user is able to generate them in the beta version of Aladin. * Need to connect to space for fully exploitation. Space-Time-MOC under development and will most likely be shown in Paris.
    • Generate and add to Mocserver
  • VOEvents:
    • Baptiste Cecconi has transformed the doc into an exact tex document, and is part of the editors:
    • Feedback gathered from specific communities (FRBs, SSO, multi-messenger follow-up) points to the need of further evolution of VOEvents.
    • How do we discover VOEvents? science driven and/or wavelength driven specification of VOEvents to be able to do TAP like queries?
  • TimeSeries Models:
    • Coords model / feedback given.
    • To be VODMLized: PhotDM, Characterisation.
  • TimeSeries Serialisation:
    • To solve some very common use cases (light-curves and such) we need a minimum of information on the filter system, the ucds are not enough.
