• Taking advantage of a short stable time-slot of the pandemic, the China-VO 2021 national workshop was held in Lijiang, a south-west city in Yunnan Province, from July 18 to July 22 2022. More than 130 people attended to the workshop in-person. The theme of the workshop is “Making Your Data and Services Ready for Al-enabled Science Discovery”.
• On July 17, the fifth WorldWide Telescope (WWT) Tour Contest Award Ceremony was held online through Shanghai Astronomy Museum’s social media platform. The fifth WWT Tour Contest in China was launched in October 25th, 2021. A total of 171 works had been collected. Near 500 students and teachers participated in the contest.

Report from the CSP

• LineTAP updates: there was a DAL running meeting to discuss about LineTAP, although I personally couldn't attend there is a good communication between the interested parties and the definition of which parameters are needed within this new protocol is underway.
• Follow up on Data formats:
  • JSON - There's been some discussion around this subject on the Slack channel of the time domain interest group. This was initiated and motivated by GCN moving away from VOEvent and adopting other messaging technologies better adapted for high cadence (Kafka / Avro). I think we should support to have some discussion within the next interop around this subject. In this context a CSP plenary session around multimessenger could set the scene as a starting point for that discussion. LVK, neutrino, SVOM, CTA, DESY,... GCN?
• The newcomers session: Hendrik asked for my participation following the same format as last time and I have agreed to take part. I think it would be great to have again a short intro by the Exec. While the meetings are still online we can continue doing this without much thought, but once the meetings are in person we need to come-up with a working solution for the newcomers session.
• The webpage ivoa.net points to a glossary for developers maintained at the twiki and which contains some technical terms and a list of acronyms. Recently some actions took place to add new terms. Hendrik and Marco have worked together to update this list. While the list has terms related to the IVOA, there are more general terms for example items such as “C+” or “ASCII” which I’m not sure should be there and there might be other terms which are missing from the IVOA vocabulary. I think the CSP with help of the TCG should revise the list and decide if some elements don’t belong there.
