  • On June 28, 2018, the IAU announced the composition of the new Division Steering Committees (DSC) and Commission Organizing Committees (COC) for the next triennium, as resulted from the recent elections. Chenzhou Cui was elected as the Vice President for Commission B2 (Data & Documentation).
  • “Informationization Working Committee” is under building. The proposal was submitted by the China-VO to the Chinese Astronomical Society (CAS) in 2017 and was approved by its standing committee.

Project report for NAVO

The NAVO registry has now implemented support for ISO Digital Object Identifiers (DOIs) and a number of NAVO services have already had these added. DOI's make it easier for researchers to credit and reference VO-related resources.

The HEASARC has fully released and validated coordinated TAP and DataLink services which provide access to all of the table and mission holdings of the HEASARC. VO-enabled tools, e.g., TOPCAT, can have comprehensive access to HEASARC holdings entirely through VO protocols.

The NAVO Python Working Group has issued its first pull request against the Astroquery library, a critical first step in establishing a NAVO role in supporting this community-driven effort to develop powerful standardized libraries to access astronomy data archives. This builds upon efforts at recent AAS and IVOA meetings.

The paper Berriman, et al., "A Study of the Efficiency of Spatial Indexing Methods Applied to Large Astronomical Databases," Submitted for publication in the Proceedings of ADASS XXVII, Santiago, Chile (2017), has been posted on Arxiv at https://arxiv.org/abs/1806.08866. Submission to a peer-reviewed journal is anticipated later this year.

As scheduled, support for the legacy VAO closeout repository will end this month. This repository holds copies of the documentation and software releases of the VAO prgram. While the repository will not be actively deleted, no further maintenance is planned and users will be pointed to more up to date sites of NAVO, the IVOA and the USVOA. The end-of-life plan for the USVAO website is being finalized with support terminating at the end of this fiscal year. The original NAVO proposal had mandated support through at least the end of FY 2017.

A special NAVO workshop was held at the AAS in Denver to demonstrate how scientists and developers can use Python to access our archival data -- typically hiding the crucial VO underpinnings in a scientist-friendly software library. Despite the smaller size of the summer AAS meetings, compared to our first workshop in January the meeting packed the room in which it was presented with about 40 people present. Having doubled the planned attendance for this meeting, we anticipate substantially increasing the size before the January 2019 meeting in Seattle and continuing these workshops as a regular event.

A substantially revised NAVO web site was released for the AAS meeting. The new web site (at https://heasarc.gsfc.nasa.gov/vo/summary ) is still under intensive development, but is intended to support the distinct interests of scientists and developers. In particular, the site provides links to the Python notebooks that we are developing for the scientist community including the notebook used in our workshops and more detailed workbooks for each center.
