China-VO

National Astronomical Data Center (NADC) was announced by Chinese government in June as one of the first 20 national scientific data centers. NADC will become the official backend platform for the China-VO.


Informatization Working Committee, Chinese Astronomical Society, was unveiled on June 13, 2019. 4 working groups established in the committee, including Research Informatization WG, Management Informatization WG, Cyber-infrastructure WG, Education and Outreach Informatization WG. IWCC is the China-VO’s position at Chinese Astronomical Society.


DAEPO activities are fruitful in the last months

  • WWT Teacher Training 2019, was held in Hangzhou from 14 until 16, August. More than 60 teachers across China attended the event. New WWT version with HiPS and VR enhancements and IAU Open Astronomy School Plan were introduced.
  • “Data-driven Education and Public Outreach”, a parallel session was organized at the 6th China Scientific Data Conference held 21-23, August. China-South Africa workshop on the "Big Data Challenge in Astronomy" was held in Shanghai, followed by "Astronomy for Development Forum" from 17 to 21, June. China-VO team completed a planetarium under the theme of IAU OAD "Astronomy for a Better World" in May 2019. IAU OAD officer, Dr. Kevendran Govender, participated the forum in the new planetarium.
  • China-VO Public Supernova Project (PSP) dataset was used in HUAWEI AI Futurelab College Student Contest. The award ceremony was held in July at University of Chinese Academy of Sciences.
  • China-VO also attends the organization of the IAUS 367: Education and Heritage in the Era of Big Data Astronomy, which will be held in Argentina in 2020.

ChiVO

CVO

The CADC has continued development of the ARCADE science platform based on Docker, Kubernetes, and a NoVNC "desktop" display within the web browser. We are also working on using Jupyter notebooks for tutorials and science tools for exploring the archive and interactive data analysis.

The CADC has implemented all of the changes and new features of TAP-1.1 (open source libraries at https://github.com/opencadc) and deployed several TAP-1.1 services. The primary CADC archive search service is one of the TAP-1.1 reference implementations. In addition, we continue to prototype new features in our TAP servies, including (i) new DALI-1.2 xtypes and (ii) an extension to VOSI-tables to allow users to create and manage their own tables in the YouCat TAP service (https://ws-cadc.canfar.net/youcat/).

CADC developers have actively particpated in Astropy and PyVO work since the successful hackathon at the Paris Interop and we are committed to ongoing development.

Euro_VO

Euro-VO partners have been active in the ESCSPE project. This project finalised a work plan for the CEVO task "Connecting the ESFRI to the EOSC via the VO", and activities have been started for helping large astronomy infrastructures to use the VO. One example is the preparation of the group of radio astronomy ESCAPE partners (SKA, LOFAR, JIVE, ALMA) to participate in the "Radio Astronomy and VO" session at the Groningen Interop. ESCAPE partners have also been active in preparing the ADASS BoF on Science Platforms.

The ESCAPE project web pages are now live at https://projectescape.eu.

ESA

• First ESDC variability portal for HCV (Hubble Catalogue of Variables) http://hst.esac.esa.int/hcv-explorer/ (video: https://youtu.be/22SGQlEGjIE)

• ESASky (http://sky.esa.int): controlling with an iframe & release of pyESASky Jupyter widget (https://www.cosmos.esa.int/web/esdc/pyesasky)

• Access to external TAPs: Gaia archive and prototype in ESASky (video tutorial: https://youtu.be/ ysycmR3C8uk )

• New HST module published in astropy.astroquery and XMM-Newton module ongoing.

• New versions of ObsLocTAP and first complete prototype server implementation for INTEGRAL archive (http://integral.esa.int/visObsTap/

• Short/medium term: Working on the update TAP services to new standards i.e TAP 1.1 and ADQL 2.1

GAVO

The GAVO Data Centers in Heidelberg and Potsdam keep maintaining and developing services. The most notable new data collection since the Paris is a mirror of the Byurakan survey developed jointly between ArVO and GAVO, which is can, in particular, be used to train for the Gaia RP/BP spectra. As usual, significant efforts also went into keeping our Registry services (RegTAP and GlotTS) up to date and keeping the whole Registry system tidy (e.g., having role="std" on all interfaces that should have it, throwing out ancient ProtoSpectralAccess capabilities).

On the software development side, numerous minor fixes and improvements went into our publication suite DaCHS, with release 1.4 planned for shortly after the Groningen Interop. Among items similar packages might want to take up are generate_series and tablesample to ADQL and an informative HTTP server header (talk during this Interop).

We also wrote and expanded software related to drafting Vocabularies in the VO 2, in particular the converters from various inputs to draft-compliant files, as well as a consumer/validator in python.

The new Vocabularies standard also was the main focus of our standards work. In addition, we prepared what we think should finally be the RegTAP 1.1 recommendation, moved ahead the catalog of ADQL user defined functions, helped with writing a proper standards text for EPN-TAP, and worked a bit on VODataService 1.2 (mainly STC coverage). We also started on SimpleDALRegExt 1.3 (essentially adding auxiliary capabilities). Also, we looked at existing implementations of TAP clients using authentication and will report on our findings at this Interop.

Thanks to the efforts of an international group of developers with major GAVO contributions, the current Debian release 10 ("buster") packages several VO client applications, including Aladin, TOPCAT, and pyVO, greatly facilitating the installation and maintenance on Debian and its derivatives.

Updates on what GAVO is doing are posted on a roughly monthly basis on https://blog.g-vo.org.

  • Telecon 2019-07-16
Five proposed reccommendations completed and submitted to Exec for approval

Four current proposed recommendations (all data models); 3 are in RFC review stage, 1 to be reviewed by TCG after document update

  • concern expressed by some TCG members that DM recommendations are severely under-reviewed without concrete usage
  • concern expressed by some TCG members that "two interoperable implementations" is very fuzzy when it comes to DMs
  • proposal to "hold" new models until we can prove interoperability by completing the VODML-mapping work (from old utypes tiger team)
TCG has agreed that we will move the development of standards documents from volute (kindly hosted by GAVO) to github
  • TCG chair/vice-chair will manage permissions and create repositories for standards (1 repository per document)
  • WG chair/vice-chair will admin and manage permissions on a set of repositories (~10)
