IVOA Roadmap for 2023B

This outlines the roadmap for development activities by the various IVOA working and interest groups between the Nov 2023 and May 2024 Interops.

Applications WG

Data Access Layer WG

Primary:

ADQL

• 2.2 - PEG, INTERVAL support, MOC support, Array support, string functions, OFFSET

DALI 1.2

• PRec by Sydney

TAP 1.2

• User managed persistent tables
• Experiment with Open API spec for these changes

Conesearch 1.1

• RESPONSEFORMAT, MAXREC
• Allow services to reject unknown parameters
• Modernize required UCDs (UCD 1.0-> UCD 1+)
• WD by Sydney (PR pending validators and implementations)

SIAP-2.0 -> Data Access Protocol v1

• Proceed with renaming, expansion of supported data product types
• Miscellaneous changes
• WD by Sydney

SODA1.1

• return extended metadata
• New transformation types
• WD by Sydney

Secondary

LineTAP

• Client and server implementations progressing
• Raise PRec once implementations ready

ObjObsSAP

• Work restarting
• New WD and perhaps PRec by Sydney

SSA

• Issue errata for minor issues already noted in github

ADQLUser defined functions

• Can functions be reconciled between GAVO and OAJ?

Data Model WG

Primary:

Spectrum 1.2 RFE:

• With exec approval
  • Update abstract with statement of model update scope
  • create/update issues for future enhancements ( vocabularies, VOUnit, invalid UCD sweep)
  • correct typo: PARAMs with no datatype
• Find/update spec lib implementation

Transform 1.0:

• implement python workflow scripts as jupyter notebooks
• proceed to RFC

ObsCore extension for Radio domain

• DM review of WD; organize resolution of any open questions.

Secondary:

Mango 1.0:

• continue refinement of content and implementations
• detail stop of V1.0 of document
• goal: concrete WD for next interop

Dataset Metadata 1.0:

• revise model per discussion in Bologna interop
• define and execute appropriate implementations (in context of TimeSeries, Cube, Mango)
• goal: concrete WD for next interop

Modeling High Energy Datasets:

• Refine Note in support of HEIG creation
• continue informal discussions of the 'club'
• goal: formation of HE Interest group

Provenance, one step:

• finalize Note, see if this can become a WD
  • as 'view of Provenance' similar to ObsCore

Other:

VODML Toolkit

• integrate toolkit usage into model repositories
• utilize to generate code package of vo-dml compliant models.

NDCube 1.0:

• work on Dataset, and High Energy should define additional workflow threads which exercise this model in other contexts.
• goal: implement any defined workflow cases

Characterisation 2.0:

• VO-DML compliant version of Characterisation model
• goal: WD by Spring 2024

Field of View:

• formalizing model basis for Aladin FoV format used by STScI and others
• goal: no stated goals this semester

CAOM:

• continue discussions with CADC about how this model fits into the IVOA ecosystem
