The USVOA met by telecon on 05Oct2017.

A face-to face meeting is planned for the January 2018 AAS.

The following are VO summaries provided by members of projects attending the telecon:

SAO/CXC: (JE/AR/RD)

• The Chandra archive group has patched RofR just prior to the October Interop. Several issues were reported by the Madrid group in May that will be addressed along with several enhancements/bugfixes. Release notes have been sent to the IVOA Registry maillist.
• The DataModel group has been working on STC-2.0 ... AR is updating the working draft version of the STC model to simplify the package tree names; MCD updated an alternate model to prototype new changes to facilitate usability with separate CoordSpace and CoordFrame to enable pre-canning each independently and incorporating 'shortcut' elements which represent common use- cases (eg: SkyCoord(ra,dec); OL is working on generation of sample files (STC snippets and TimeSeries) using both models for comparison.
• The Chandra archive archive operations group has been implementing MOCs of Chandra Public data. They utilized a Javascript library developed by CDS for visualization of the MOCs with Aladin Lite. A problem in the library was addressed by the CDS developers.

• The NRAO archive is in a Public Test phase. The archive is built on VO-level protocols.
• The VLA sky survey project has passed its operational readiness review and began observing on the 7th September 2017 (MDT). All raw visibility data from the first half of the first epoch, which is being observed in the VLA's B-configuration during semester2017B, are available immediately from the NRAO archive.

• We worked with Caltech/IPAC-NExScI (Bruce and John) on a study of the impacts of a couple indexing techniques on DB query performance. Bruce presenting an interim report on that at the last interop and has a talk on it at the upcoming ADASS.
• I have been working a bit with the DM WG (esp. Mark, Omar, Laurent and Gerard) to discuss and study the proposed VO-DML mapping scheme. For a number of reasons, I haven’t done as much as I want on this, but the work is ongoing.
• Theresa completed work on being able to log into the publishing registry to add or maintain your own resources. This capability has gone away with the VAO and NSCA, but is now supported via the STScI Single Sign On infrastructure. We had hoped to make that operational this week, but some system upgrades too precedence, so we’ll do that next week before the meeting.
• In the last few months we deployed a TAP service for accessing our CAOM database that contains references to all MAST observational products.

• BB noted IRSA completed their release of archive data access using SIA2 and SSA protocols. This work completes the 3 year NAVO contract.
• There was also a NAVO proposal that was prepared in April/May that was recently approved for the next 3 years. NAVO is currently planning anoutreach session at the Jan AAS. The session will inform attendees how to access NAVO archive data with Python.

• WOM said that the discussion on Big Data and LSST Use cases and comparing them to the IVOA protocols was of interest to follow up on. (Discussed in agenda item 2). He also was interested in a VOevent review and ADQL and noted that he expected a few gaps. WOM won’t be at the IVOA meeting but 3 others from LSST will be attending.
