Registry Sessions at the IVOA June 2026 Interoperability Meeting

[ back to main programme page ]

Schedule

Registry Session #1: Thursday June 11, 2026 @09:00-10:30 CEST (Session #12) Room Terra
Speaker Title and Abstract Materials Time
Renaud Savalle (PADC) Intro and Documents Status
Review of current WG work 		pdf 5
Baptiste Cecconi (Observatoire de Paris) Extended Registry Prototype
Presentation of a prototype extending registry using a graph database and an SPARQL interface, ingesting metadata from the IVOA registry as well as from Datacite (dataset DOIs) 		pdf 10+5
Gilles Landais (CDS) Export registry records with DCAT vocabulary
In this presentation, I will introduce DCAT and its current usage and how it could be an alternative of the current OAI-PMH output of the registry. Then I will present the implementation in the CDS registry which consists in mapping the Registry (VOdataService and VOResource) into DCAT. This implementation, based on a simple XSLT transformation, could be generalized for the full registry. Finally, I will conclude with the needs to improve the DCAT and registry output. 		pdf 10+5
Tamara Civera (CEFCA) The CEFCA Publishing Registry
The CEFCA Publishing Registry is a publishing registry infrastructure developed at CEFCA/OAJ to support the integration of OAJ images, catalogues and associated Virtual Observatory services into the VO ecosystem. It enables the publication and discovery of resources related to multiple surveys and data releases. This contribution presents the motivations, design principles, architecture and current status of the system. 		pdf 10+5
Markus Demleitner (Univ. Heidelberg/GAVO) VODataService 1.3
With VODataService 1.3 in RFC, we summarise the major changes (table stats, product types, data sources) and ways in which they can already be tried for the benefit of reviewers and everyone else. 		pdf 10+5
Markus Demleitner (Univ. Heidelberg/GAVO) DALIInterface
We have modelled complex interfaces (query plus capabilities plus tables plus perhaps async) the wrong way for a long time, abusing vs:ParamHTTP in various ways that immediately broken when we wanted to add auth. This has been discussed in the vintage 2019 caproles Note – and then largely forgotten over the pandemic. Well, the problem hasn't gone away, and we should think about how we will make progress. The current TAPRegExt WD could be a good opportunity. Can we forge some consensus on how to go on?. 		  10+5

Registry Session #2: Registry Hackathon: Thursday June 11, 2026 @11:00-12:30 CEST (Session #13) Room 103
Speaker Title and Abstract Materials Time
Tess Jaffe (NAVO) Registry Hackathon
The Registry Working Group is keeping a project board on GitHub where we can track and discuss issues with the metadata in the Registry. Incorrect or missing metadata make services and/or datasets harder to find, so fixing these issues to make a more complete and consistent Registry will improve the functioning of the entire VO ecosystem. Please come to our Spring Cleaning Hackathon at the Interop if you are interested in issues related to your own services' metadata or if you are interested more broadly in how to enable VO clients to find the right data and services. Current topics to get started with include: consistency among Registries; the usage of UCDs to describe tabular data; subject and concept metadata and the UAT; spatial coverage; and whatever else participants are interested in discussing and/or hacking on. Take a look at the Python notebook with examples of how to evaluate issues across the Registry or at specific publishers. 		GitHub repo 90
