   * 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

---++ Grid and Web Services WG
   * Execution Planner

Technical Note migrated to Working Draft

<a href="https://github.com/ivoa-std/ExecutionPlanner" title="https://github.com/ivoa-std/ExecutionPlanner">https://github.com/ivoa-std/ExecutionPlanner</a>

Two prototype implementations ongoing to check the consistency of the WD

- Dave Morris and Sara Bertocco

- ASTRON one in the context of SRCNet

   * Working Group new Name

Some names proposed at:

Converging to "Distributed Services and Protocols" - proposed by Dave Morris

---++ Registry WG
---++ Semantics WG
---++ Data Curation Preservation IG
---++ Education IG
---++ Knowledge Discovery IG
   * ML-proofing existing and future science platforms:<br />
      * 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
---++ 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
---++ Theory IG
---++ Time Domain IG
<p dir="ltr">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.</p>
   * <p dir="ltr">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 <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/VOEvent/20110711/&source=gmail-imap&ust=1690909773000000&usg=AOvVaw3tMK7cYHcVaSOl9jfM-q00" target="_blank">https://www.ivoa.net/documents/VOEvent/20110711/</a></p>
   * <p dir="ltr">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) =&gt; <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/Notes/CubeDM/20190318/index.html&source=gmail-imap&ust=1690909773000000&usg=AOvVaw3b-FZEf9Zb6HbmC0aO7nFO" target="_blank">https://www.ivoa.net/documents/Notes/CubeDM/20190318/index.html</a></p>
   * 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?
   * <p dir="ltr">Status of (S)TMOC =&gt; Space and Time coverage =&gt; Does this require updates? Is it currently being used? <a href="https://www.google.com/url?q=https://www.ivoa.net/documents/MOC/20220727/index.html&source=gmail-imap&ust=1690909773000000&usg=AOvVaw2lchjaDya3oBdU4ZR4gDn7" target="_blank">https://www.ivoa.net/documents/MOC/20220727/index.html</a></p>
   * <p dir="ltr">Cone search service that allows for time constraints</p>
   * <p dir="ltr">Other, dormant documents: &lt;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)"&gt; VOEventRegExt &lt;/a&gt; =&gt; Extension of the VO registry to describe a service providing VOEvents (dormant still 2014 ); [[STC]]-S =&gt; Space Time coordinate linear definitions (dormant still 2013)</p>
