Report from the TCG

• Feb. 26th, Mar. 31st vconfs
• reviewed VOEvent-2.1, MANGO-1.0, DocRegExt -1.0 RCF status --> forwarded to Exec for approval
  • DALI-1.2 still in RFC
  • works progressing on other documents: VOTable, VODataService, and the ObsCore & connected notes
• DataOrigin -1.2 has been Endorsed by TCG (document should appear soon online)
  • discussing it, EN raison d'etre and (optional) review process turned out to be unclear: needs discussion (DocStd based)
• connection among DM and the other WGs still needs to be discussed, a workshop seems unfeasible, need to find a strategy there
• interop preparation: ongoing (quite a bunch of plenaries)
  • maybe need a 2nd announcement?
• IGs to CSP interfacing: some discussion, some feedback (but it's not in TCG hands)
• TCG members have been alerted about the expiration dates of some of the roles
