Reports from the Projects






On 13 January, the implementation plan for astronomical term formulating was approved by experts organized by the China National Committee for Terminology in Science and Technology (CNTERM). The plan will rely on the National Astronomical Data Center (China-VO) to set up a secretariat, and then set up the China National Committee for Terminology in Astronomy. This will provide new opportunities for the fusion of data, publications, and communities to advance Seamless Astronomy.



A special session at the European Astronomical Society conference (10-14 July, Krakow, Poland) is being organised:

"Science with the Virtual Observatory: status, success cases, the future"

The special session will be on 12 July and will have 3x90 min sessions.

DEADLINE for Abstracts: 01 March 2023.

Science with the Virtual Observatory: status, success cases, the future

Aims and scope Virtual Observatory (VO) is a well known and firmly established global collaboration, with demonstrated capacity to provide smooth access to astronomical data, theoretical models, simulations and analysis tools. All these immense resources of different kind can interactively operate thanks to complete and flexible standards, which are continuously revised.

By including major archives from important data centres such as NASA, ESA, ESO, and ALMA, VO has helped the community to optimize and improve their science findings, through better data analysis, exploitation, and mining. These achievements are paving the way for an even more brilliant future with cornerstone projects like SKA, Rubin Observatory and Euclid implementing VO standards in their archives infrastructures, and also by new IVOA groups working in the definition and implementation of standards and services for radio, time-domain and multi messenger data. The link between the Virtual Observatory and Artificial Intelligence and the development of Science Platforms to integrate VO in the Science Cloud are also hot topics in the IVOA roadmap.

This Special Session will bring together the European astronomical community around the major results achieved by its members, preferentially using the Virtual Observatory. It will be a forum where the most successful use cases of VO may be shared, and also a site where the major challenges for the coming years may be identified.

We foresee an active and highly multidisciplinary workshop. The topics will range from purely astrophysics success cases to more technical developments involving services, ML, AI, and data mining. At least one invited talk for each block is scheduled. The program will be completed by oral contributions and scheduled e-poster slots, in a format "one minute-one slide" per e-poster.

Young researchers are specially encouraged to present their science results using VO, both as oral contributions or as e-posters.

Report from the TCG

o The TCG met on Jan 25 and has a next mtg planned for Mar 8

o TCG passed “Vocabularies in the VO” and passed on to Exec; currently reviewing MIVOT as their highest priority - Model Instances in VOTables (MIVOT) defines a syntax to map VOTable data to any model serialized in VODML. The annotation operates as a bridge between the data and the model. Hope to pass at our next meeting

o Roadmap 2020B have been updated for all WGs; few IGs still TBD

o Initiated efforts toward the interop

o Marco has details as LOC chair on venue and plans

Report from the CSP

  • The CSP met on the 17 Jan and has a next meeting planned for the 21 of Feb.
  • Agreed on proposing one or two plenary sessions around science platforms and a session DOI
  • Datalink can have a session in DAL for discussion. Follow-up by DAL
