This page collects specification issues as well as proposals for extensions for VODataService 1.1. Version 1.2, addressing most of the points below, is currently a working draft (of 2018-10).

Specification Problems

  • In current VODataService tableset, table structure is implied to be schema.table; ADQL table references, on the other hand, have one to three elements. This should be reconciled; I propose allowing table-s as direct children of tableset and prescribing full ADQL table references in table/name. -- MarkusDemleitner - 2015-05-05
    • This is in current 1.2 drafts, except that we now use anonymous schema elements for instead of having direct children (because it's saving migration in RegTAP).
  • VODataService has no provisions for how SQL delimited identifiers are to be handled where that is relevant (e.g., in TAP tables endpoints). I propose to explicitly say {schema/table/column}/name "must be in forms ready for application" and mention ADQL and the respective symbols as examples. -- MarkusDemleitner - 2015-05-05
    • This is in current 1.2 drafts.
  • ParamHTTP (and perhaps others) resultType is 0..1. With DALI RESPONSEFORMAT, that should probably be made 0..n. Or perhaps we should just adapt TAPRegExt's outputFormat, which already models DALI? -- MarkusDemleitner - 2018-03-16
    • There do not seem to be terribly important use cases for resultTypes. So, we'll probably leave this alone in 1.2.
  • For many reasons, we DataCollections should be allowed to have capabilities. -- MarkusDemleitner - 2018-04-18
    • This has been solved by deprecating DataCollections and using CatalogResources instead.

Suggested Extensions

  • Have some markup to say what dataproduct types the service will return? This would be particularly useful with ObsTAP ("what services have time series?"). -- MarkusDemleitner - 2018-04-18
    • No satisfying solutions have been suggested so far.
  • Add numerical/MOC coverage (see RegSTC note) -- MarkusDemleitner - 2018-04-18
    • This is in 1.2 drafts.
