- Participants from 17 countries, most of them early-career people.

- High percentage (60%) of VO newcomers.

- Very positive feedback. Many people interested in a second edition covering new topics.

- The school was conducted in Spanish so part of the material is in Spanish.

- The school was recorded and the recorded sessions are available from the school web page so the reached audience can even be larger.

+ EAS2023 SS4 "Science with the Virtual Observatory" ( https://eas.unige.ch/EAS2023/session.jsp?id=SS4)

- The deadline for abstract submission was March 8th.

- We received 16 requests for talks and 7 for posters.

- In the coming days the reviewing process will begin.

- Pursuing FAIR standards for CfA data - recent meeting with SMA & NRAO to exchange information on formats and standards; working to map Obscore keywords to SMA Radio data; Also Obscore review and use in Chandra - performed inventory and reviewed if a high energy extension was needed

- Work on Science Platform IR&D project using Rubin Science Platform application for CfA use - Instatiated the Platform at CfA - coordinating with RSP lead on topics to discuss/resolve;;

- Populating DOIs in Chandra Source Catalog 2.1 prodiuction run and migrating previous catalog formats (CSC 2.0) to current DOI format

- Contribute to IVOA DM pursuits: MIVOT 1.0, Spectrum DM RFE, moving forward on Dataset and Transform which will lead when completed to a data cube model. Data Cube model will support 1,2,3 dimensional data including the event list used by photon counting high energy projects (e.g., Chandra).

- Initiated HIPs project to automatically produce HIPs for Standard Processing at TBD cadence; thinkng about HIPS for the Chandra Source Catalog next.
