The main IVOA related activities are continuing developments of the CASDA archive interfaces and implementations of IVOA standard protocols. The other activity is related to the homogenisation of the AAO data holdings, which also includes the implementation of IVOA interfaces. The First data release of the MWA GLEAM survey will be announced this week and the access is also supporting VO standard protocols. Recently a call for expression of interests has been released to propose projects in the area of eResearch in astronomy which also opens new opportunities to fund VO related activities, which are specifically mentioned in the call.

Aliyun becomes strategic partner of the China-VO

On 13 Oct., Yan Jun (Director of National Astronomical Observatory of China, NAOC) and Hu Xiaoming (President of Aliyun Cloud Computing Co., Ltd.) announced the news in the 2016 Computing Conference hold in Hangzhou (https://yunqi.aliyun.com/). Aliyun is the largest public Cloud computing service provider in China, and the No. 3 in the world.

As strategic partners, NAOC and Aliyun is planning to establish “NAOC-Aliyun Astronomical Big Data Joint Research Center”. Chinese Virtual Observatory (China-VO) will be immigrated onto Aliyun platform to enhance its capability as a full lifecycle data management and open access environment.

Within a few days of its release by ESA, IRSA has integrated the Gaia DR1 release into its holdings including its VO interfaces. Through these, this major new dataset can be accessed directly at IRSA or through MAST's Portal, the HEASARC's Xamin, and other VO-enabled tools. All of IRSA's hundreds of tables are visible through the VO -- including the new Gaia tables -- and are now marked in the VO registry as accessible through their general table access protocol interface.

NED plans an October release of a complete version 2 image access service to NED's holdings allowing for data selection by position, name, spectral regime, resolution and other criteria.

In our NAVO indexing study, IPAC and STScI have each benchmarked a million spatial queries against the 2MASS All Sky Point Source Catalog. This table had been loaded into PostgreSQL databases set up at their institutions. Both sites have tested multiple geometrical indexing schemes. Early results suggest that the differences due to the geometry choices were small but there were significant differences seen due to the hardware/operating systems/networks tested at the two sites.

NRAO:

The Next Generation Archive for VLA/Alma in work
- Archive built upon VO
- In wide spread testing internally; plan to make available to public later this year . VLA sky survey
- Discussing with group in Canada; would include enhanced data products and accompanying work flows; still in evaluation

SAO/CXC:

Iris 3.0 beta1 - currently in test; planned demo at IVOA
- Mostly infrastructure work
- Replaced Visualizer with STILTs plotting API and plotting backend
- Added CDS plugin for SED data (ASDC & NED there from previous plugins)
Several iterations on Chandra archive interfaces to clear issues with HEASARC Operations reports
DataModel & Registry of Registry efforts for IVOA;

STScI:

SciServer from JHU loaded locally and under review – evaluation in progress
ObsTAP – Observation Multi Mission DB; rolling out several table over the next few months
DM group – TD working on VODML effort; How can it be represented in VODML serialization; Found mapping syntax too complex; involves VOtable – joint App/DM session planned at Interop for discussions
