Difference: VOTable15RFC (1 vs. 8)

VOTable 1.5 Proposed Recommendation: Request for Comments

VOTable is a standard for the interchange of data represented as a set of tables, and includes both table metadata and the data itself.

Summary

Latest Draft: VOTable 1.5 (Proposed Recommendation)

The main purpose of VOTable 1.5 is to support refposition attribute analogous to TIMESYS.

VOTable 1.5 is a backward-compatible revision.

The other main differences between version 1.5 of VOTable and the preceding version 1.4 are:

To Do Upon Approval, Prior to Upload

• Change version attribute in schema to "1.5"
• In the document, set the \ivoatype to "IVOA Recommendation" and set the status text according to the official wording is in DocStd.

Future

The VOTable GitHub Issues page contains a list of issues and proposed future enhancements. It is the main mechanism for contributing to the standard.

Reference Interoperable Implementations

DaCHS produces COOSYS refposition in TAP results from the gaia.dr3lite table in the GAVO Data Center TAP service which can be read by the latest versions of STILTS and TOPCAT. For example:

• STILTS shows the metadata from the GAVO TAP results:
  • stilts tapquery tapurl=http://dc.g-vo.org/tap sync=true adql='select top 1 * from gaia.dr3lite' ocmd=meta

• STILTS rewrites the VOTable from the GAVO TAP results, including the COOSYS refposition:
  • stilts tapquery tapurl=http://dc.g-vo.org/tap sync=true adql='select top 1 * from gaia.dr3lite' ofmt='votable(version=V15)' | grep COOSYS

• TOPCAT's Columns Window shows that same metadata for those same GAVO TAP results.

Implementations Validators

• The latest version of STILTS (v3.4-10) validates VOTable 1.5 with the following command:
• stilts votlint my_votable_file.xml

• The validates VOTable 1.5 by following these instructions:
  • Click on Load for VOTable.
  • In the empty text box below "URL of the service to validate:", enter the URL of a VOTable to validate.

RegTAP 1.2 Proposed Recommendation: Request for Comments

RegTAP, formally known as the IVOA Registry Relational Schema, is the standard way for clients to query the VO Registry. Version 1.2 adds tables to give the coverage in space, time, and spectrum and a tap_table view intended to replace GloTS. To make use of these features, we require a few optional ADQL features and the extra UDF ivo_interval_overlaps.

Latest version of RegTAP can be found at:

• https://ivoa.net/documents/RegTAP/20240124/
• Bleeding edge versions during RFC can be built from the sources, which are kept on github. Feel free to open bugs or pull requests there at any time.

RegTAP is a fairly long standard. For review, it is probably advisable to only skim the unchanged text. For the purposes of this RFC, it is probably sufficient to closely inspect sects. 4.5, 7, 8.15 through 8.18, 9, and 10 (in particular 10.13). See also appendix E.

Reference Interoperable Implementations

Server-side implementations exist in the TAP services at http://reg.g-vo.org/tap and https://registry.euro-vo.org/regtap/tap.

Client-side code exploiting the new spatial tables is present in pyVO; WIRR also has constraints on coverage in space, time, and spectrum.

Support for tap_tables is less common; however, once the data providers fix their metadata records, the content of tap_tables essentially is equivalent to what we already have in GloTS, and hence the editor would argue that all clients using GloTS (e.g., TOPCAT) count as reference implementations of tap_tables.

Implementations Validators

A validator is part of the source distribution at https://github.com/ivoa-std/RegTAP. See the validator subdirectory. Note that it requires a registry seeded with the data provided, and hence the suite can only be used by the service operators.
