Reports from the Projects

NOVA (Argentina)

ArVO (Armenia)

AstroGrid (United Kingdom)

ASVO (Australia)

BRAVO (Brazil)

China-VO

• The annual meeting, Astroinformatics and Virtual Observatory 2025, will be held November 26-29, 2025 in Hainan. 180+ participants have been registered. The theme of the meeting is "API&MCP". Driven by API&MCP, we hope to provide the community with FAIRable and AI-ready services. More information about the meeting is available at https://nadc.china-vo.org/events/cvo2025.

CVO (Canada)

ESA (Europe)

Euclid iDR1 (internal Data Release 1) was released on 31/October/2026. The Euclid archive has been serving data through all standard data access protocols (TAP, ADQL, DataLink, SIA, SSA, SODA, VOSpace).

Big effort has been carried out to contact all VO Resources providers, indicating potential errors encountered when running the corresponding validators. Very good response rate and resources improvement. Dedicated presentation will be provided at the Operations WG session.

As part of this effort, we have started to fix our VO services from some of our archives, with various TAP services (JWST, Hubble, Integral, XMM-Newton) now being fully compliant.

A new version of the Euro-VO Registry 5.5 was released, with a new validator for the Object Observability Simple Access Protocol (ObjObsSAP) services, and some improvements of the other validators.

Euro-VO (Europe)

GAVO (Germany)

GAVO's Heidelberg data centre keeps adding resources at a rate of a few per semester. A rather interesting one this semester is Carmenes DR1, which has radial velocity time series (for which we still need an equivalent to Ada's note on photometric time series) together with the spectra they were drived from. Also, the input format is very close to the new EPRV standard (although we output it in a VOTable serialisation).

We also keep maintaining our server package DaCHS and contribute to pyVO. In standards, we work on developing VODataService (e.g., safely distinguishing simulated from observational data), contributed to data origin, VOEvent registration, and much else. We also keep contributing to the UAT working group.

Organisationally, the GAVO Data Centre is going to move to Görlitz until 2028. It will grow into what will be called the GADC ("Görlitz Astronomical Data Centre"). We will be hiring a 5-head crew that will sustainibly operate it (including the reg.g-vo.org RegTAP service), maintain DaCHS, participate in the IVOA, do VO education in Germany and beyond, and so on.

JVO (Japan)

Kazakhstan VO

NLVO (Netherlands)

OV-France

RVO (Russia)

SA^3 (South Africa)

SKAO (Square Kilometre Array Observatory; Australia & South Africa)

• Construction Progress - SKA Low, Australia AA0.5

  • 14,000 antennas deployed, about 10% of the total array, 5 dishes assembled for SKA Mid

• Science Data Platform (SRCNet):

  • Spain, Switzerland, Sweden, the UK, China, Japan, SKAO small node, Canada and Italy have passed accreditation process for SRCNet nodes. Ingestion node in Australia

  • SRCNet 0.1 tested. First public version (Science Verification) expected for Q1/2 2027

  • Use of multiple IVOA protocols (TAP, DataLink, metadata models)
  • Helping with the evolution of IVOA to new authentication/authorisation mechanisms (tokens)
  • Using CERN modules like Rucio for data management (like Vera Rubin). Rucio community Workshop organised by SKAO last week and they want to find a way to collaborate with IVOA (in particular on how to connect data with specific domain metadata)

SVO (Spain)

UkrVO (Ukraine)

USVOA (United States)

VO-India

VObs.it (Italy)

• Orgnised the 1st Tech Forum for the Astro-CC project; it was held in INAF-OATs 7-9 October, offered enough room for standards and interoperability discussion, relevant for the EU partners: some content will be reported in interop's sessions.
• Held a seminar at the Master on Data Management and Curation, organised for students and PhDs by Area Trieste and SISSA: IVOA history, status and challenges.
• Besides efforts in DAL, DSP, Radio groups, some efforts seems to restart on Theory topics (cross fingers).

Report from the TCG

• TCG met 2 twice (as usual) since last Exec
  • Sept. 25th and Oct. 29th
  • plus the hybrid meeting that just happened (Goerlitz, 13 Oct. 13:30 UTC)
• 2025 Northern Fall's Interop's program has been prepared and discussed
• work has progressed on documents (on track docs here, see others below)
  • VOEvent-2.1: waiting a few changes before TCG re-review
  • StandardRegExt -1.1 (that has been approved by Exec)
  • MANGO-1.0 undergoing review
  • DALI-1.2 has just started RFC
  • DocRegExt -1.0 has just started RFC
  • DataOrigin -1.1 has been proposed as PEN
  • work in ongoing at various level in Vocabularies
    • full vocabularies
    • VEPs
    • UCDs vocabularisation
• Radio & HE (&TD) ObsCore exts. are progressing
  • dedicated meetings and session
• astronet.ru decision
• IGs coordination roles still to be discussed (but planned)
• TCG pinged about roadmap preparation (and potentially thinking if it needs changes)
• Documents Standards will need some time and brainstorm to get to something useful
  • tech-side might provide us some hints
  • see "dedicated" session on Sunday
