IVOA Roadmap for 2022B
This outlines the roadmap for development activities by the various IVOA working and interest groups between the Oct 2022 and May 2023 Interops.
Applications WG
Data Access Layer WG
ADQL- 2.1 - Feature complete - validation being finalised
- 2.2
- Vector extension
- move from BNF to PEG for language specification
ADQL User Defined Functions
-
ADQL astrometry library
- GAVO and Vizier implementation of coordinate transformation
- Functions added in pgsphere
TAP
- Allow ROT13 for encoding of
ADQL query strings?
SIAP-2.0 -> Data Access Protocol v1
- Expanding to cover spectra and potentially measurement sets and catalogues
- One shot cutouts from SIA2
- Renaming SIA2 to reflect expanded role
- Work continues in new
GitHub repo:
https://github.com/ivoa-std/DAP- New WD by May interop
SODA-1.1
- Errata for MOC parameter, rebin/project, pixel cutout
- One shot cutouts from SIA2
- Cross-join of parameters
- Metdata
- Select output by dataproduct_type
DataLink 1.1
- Working draft out
- Needs implementations before RFC
DALI-1.2
- multipolygon still pending
- otherwise ready for PRec+RFC (Q1-2023)
SSAP
- Minor revision to
- make coverage information non mandatory
- Explain SSA utype prefix
- Longer term function is covered by DAP +
SODA
ConeSearch -1.1 [in connection with TD IG]
- work will progress to close issues
- a new WD before May 2023 Interop ?
LineTAP - Intended to replace SLAP
- WD before May 2023 Interop ?
ProvTAP - Continuing work towards mature WD status
TAPRegExt [in connection with Registry WD]
- WD release in Q2-2023
ObjVisSAP - PR-1.0 nearly there
- implementations ready
Following Radio IG, TD IG activities for requirements
- refer to the roadmaps of these IGs for details
Data Model WG
Grid and Web Services WG
- SSO - working towards next WD based on tokens and delegation.
- ExecPlanner - working towards first WD
- Science Platforms - continue collaboration with Theory IG and KDD. What are the IVOA services to build a SP? Do we need some new standardization? What kind of interoperability are we looking for?
- JSON-ification - small team of interested parties to look at what is easy and what is hard. Is it possible to move from XML to JSON? what is the effort needed?
Registry
Semantics WG
On the REC track, Semantics still has the RFC for Vocabularies 2.1 (on
github procedures) open. We will try to gather the missing WG reviews
during November and thus hope we can pass the document on to the Exec in
December; we do not see much potential for controversy in the new
regulations.
We also hope to release a Proposed Recommendation for VOUnits 1.1 before
the end of 2022 and aim for RFC in January 2023. Given that the update
addresses the difficult question of empty and missing units, that RFC
could be more involved.
The UCD list 1.5 should be available for TCG review right after the
Interop. We hope that it will be endorsed at the next TCG meeting, or
perhaps the one after that.
Once that is done, the cycle for the UCD list 1.6 will begin in earnest.
This will, in particular, comprise UCDs useful to annotate columns
containing metadata on ambient conditions for observations.
Beyond the Semantics WG's documents, we intend to drive along a new
release of VOResource with the main goal of clarifying how the UAT is
intended to be used within VOResource. Unless the Registry WG has
additional items in this update, we expect this will be another easy
update.
Outside of the standards track, we still work on the product-type
vocabulary that needs to be ready for Datalink 1.1. We also work on the
facility nomenclature and hope to produce a note discussion the intended
practices between the IVOA and wikidata before the next Interop.
Finally, we will continue to process
VEPs in the context of maintaining
the vocabulary repository. By this activity's nature, we cannot predict
at this point how much effort will be required for that.
Data Curation Preservation IG
Education IG
Knowledge Discovery IG
Operations IG
Ongoing activity:
- Monitor VO health
- Coordinate "weather reports" (service compliance)
- Address non-compliancy:
- Identify common/persistent errors
- Support/encourage service operators to improve service compliance
- Work with WGs on standards-related issues
- Validation:
- Ensure validators are available (IvoaValidatorsSummary)
- Encourage use of validators
- on deployed services
- during standard development
- Communication
- Provide forum for discussion of operational issues
- Host/invite "site reports"
Specific focus:
- Work with DAL on standards issues:
- ConeSearch: UCD1+
- DALI: Sexagesimal markup standards
- SSA: A couple of Errata suggested
- Push for service metadata improvements:
- Upcoming themes:
- Operations in the cloud
- Authentication as an operational necessity
