New draft 2.1 or 3.0 is being evaluated. SaraBertocco has the lead on this activity
 

 Software Discovery
 
Discussions on the need for a discovery protocol for software discovery with enough information for execution. Expected colaboration with DAL
 Registry WG [from 2025A] 
 

 CURRENT FOCUS 
 Investigate "Serving Simulated Data in VO Services/Collections" 
 cf https://wiki.ivoa.net/internal/IVOA/InterOpNov2024DAL/DAL_at_IRSA_Laity.pdf
  Open question: reuse SSAP datasources for VODataService ?
 
  Support data publishers towards filling coverage information as MOCs in publishing registries according to REC RegTAP -1.2
  Participate in "alternative links" in DataLink effort with DAL WG to publish cloud-based data products - cf https://github.com/ivoa-std/DataLink/issues/117. Also investigate with DPS (ex GWS) WG if necessary to have such metadata in the Registry.
  Prepare future RegTAP -1.3 to facilitate searching by product type served after VODataService -1.3

 work on an "IVOA vocabulary" version of the UCD list. 
 
  Work on OntoPortal-Astro 
 Consolidate Advisory and User Group
  Develop new version with : ontology FAIR evaluation, recommender/annotator, ontology browsing and mappings, advanced APIs
 
 

   The current roadmap has strong interaction with the Solar System IG.

  Continue efforts on a DOI note
  Promote Data Origin (see http://ivoa.net/documents/DataOrigin/) to working Group ( Data Model, DALI?) in order to have a basic Provenance in the VO
astropy  astropy.io.votable.dataorigin  module available in version 7.1
  Investigate standard used in scientific community (eg DCAT). Make the bridge with Open Science
  Promote Bibliographic Interfaces (see https://www.ivoa.net/documents/Notes/BibVO/20240214/index.html)
  Investigate data curation aspects to feed AI: legal aspects, citation, etc.

 HEIG Goals: 
 ObsCore continuation - Continue with HEIG Note on Obscore extension for HE data; coordination with DM WG & others to move this to WG level
  VOEvent - followup/continuation from the side-meeting we had in Malta; form a plan

 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"
  Encourage feedback communication between ops services and data providers
 
 
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: 
 VOUnits, UCDs
 
  Operations in the cloud
  Security in VO services 
 Encourage TAP validators developers to add checks for sql injection susceptibility
 
  Authentication as an operational necessity
  User agents used in VO services clients

 EPN-TAP 2.1 
 progress in various domains (sort out heliophysics and body-fixed coordinate frames, start small bodies taxonomy)
 
workflows 
 Installation tests, mock-up service
 
use cases 
 Collect some in planetary science & heliophysics
  start generating more tutorials / education actions
 
Expose planetary content from telescope archives
