New Actions


WG/Apps (TD/RD)



Issues: (from Feb telecon - needs update)
  • Service Weather report on DAL protocol "SHOULD"s: collected data providers view, need to report (here, e.g.)
  • polygon CCW: modelling seems solved (errata in other WGs), data providers side, how to proceed?


  • 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:
  • 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)



Issues: (from Feb telecon - needs update)
  • XML Schema Versioning - issues to be addressed

WG/Registry (ThD/PLS)


WG/Semantics (ML/MD)


IG/Data Curation & Preservation (AS/TJ)


IG/Education (CC/HH)


An EduIG session is under preparation and a plenary talk is confirmed


More people are encouraged to attend to the Interop.



IG/Ops (TM/MT)


IG/Solar System (BC/SJ)


IG/Theory (CR)



Issues: (from Feb telecon - needs update)
    • 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.
