Data Curation Preservation IG
- Good practices to provide Data in the VO -
- Provide a DOI reference note - (to improve Data citation)
- Promote Data Origin (see http://ivoa.net/documents/DataOrigin/) to working Group (DALI?) in order to have a basic Provenance in the VO
- Investigate standards use in Open Science and their potential usage in the VO (eg: DCAT)
Education IG
Knowledge Discovery IG
- ML-proofing existing and future science platforms:
- Are existing astronomy science platforms compatible with ML methods?
- Investigate whether science platforms can access tabular and non-tabular data through VO interfaces.
- Building libraries of well-established pre-trained models and integrating them in science platforms.
- Designing a questionnaire to collect user requirements for science platforms to support ML methods and see how it fits into the plan of science platform from the developers' and relevant service providers' side.
- Artificial Intelligence and Large Language Models in the VO
- Coordinating an IVOA, inter-group "tiger team" that will scope the current and future potential impact of AI on VO.
- Collecting use cases and requirements for the integration of commercial and/or ad hoc LLMs models in IVOA-relevant topics.
- Investigating best practices to integrate LLMs with VO tools for a fusion of domain knowledge and data.
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
Radio IG
- Complete and implement (2 implementation) the radio Obscore Extension under the resonsability of DM WG
- Improve Pulsar Radio data Note in collaboration with TDIG
- Start version 2 of Implementation review note
Solar System IG
- Continue development on Observatory Facility Codes
- Vocabulary Development:
Theory IG
Time Domain IG
Priority in 2023B is to continue the discussions and review of the VOEvent standard, and align it with current practices for transient alert reporting, Expertise from ZTF, and broker alerts for Vera Rubin will be reviewed and hopefully incorporated into a new version of the standard.
-
VOEvent 2.1 working draft: new version coordinated by DAL, but the TD IG should follow and read the draft to provide feedback. The current, stable version of VOEvent is at https://www.ivoa.net/documents/VOEvent/20110711/
-
Pick up discussion on Time Series Cube Data Model (2019), to get status, establish if it leads to a recommendation, etc. Does the datacube only have a time dimension, or also a spectral dimension? Of relevance for upcoming spectral time domain surveys. We need to ensue that it also fits high energy data (i.e. event files) => https://www.ivoa.net/documents/Notes/CubeDM/20190318/index.html
- Time search postponed in the Cone Search standard to the next major release
- Evaluate synergies with HAPI protocol for heliophysics time domain data (https://vires.services/hapi/)
- Form Galluzzi's talk at interop: radio time/frequency datasets. Similar to GW transients. Are there standards for this?
-
Status of (S)TMOC => Space and Time coverage => Does this require updates? Is it currently being used? https://www.ivoa.net/documents/MOC/20220727/index.html
-
Cone search service that allows for time constraints
-
Other, dormant documents: <a href="https://wiki.ivoa.net/twiki/bin/edit/IVOA/VOEventRegExt?topicparent=IVOA.2023ARoadmap;nowysiwyg=0" rel="nofollow" title="VOEventRegExt (this topic does not yet exist; you can create it)"> VOEventRegExt </a> => Extension of the VO registry to describe a service providing VOEvents (dormant still 2014 ); STC-S => Space Time coordinate linear definitions (dormant still 2013)
