[ back to main programme page ]

Session Schedule

DAL & Registry Joint Session: Friday November 14, 2025 @14:00-15:30 CET (Session #3) Room Nadir
Speaker Title and Abstract Materials Time
Markus Demleitner (GAVO) Simple Cone Search 2 and Transitioning To It
I will report on my plans for making the venerable cone search DALI-compliant: What can stay, what has to change, and what new features we might cheaply get on top. An important part of this endeavour is working out how to get to an SCS2 world from the current VO with minimal disruptions. I will show a plan and an optimistic scenario for that. 		pdf 10+5 mins
Markus Demleitner (GAVO) Finally: Towards TAPRegExt 1.1
TAPRegExt has had a rather clearly defined deficiency for several years: Its use of a vs:ParamHTTP-typed interface. Still, the standard sat idle. Now, thanks to a requirement to declare per-mode (sync/async) limits, there is renewed interest in it. I will discuss two proposals to address that later issue, and remind you of a plan to address the Interface Problem (also known as caproles). 		pdf 10+5 mins
Erik Mellegård (WinterWay for ESA) The Euro-VO Registry is adding validation support for the Object Observability Simple Access Protocol
The Object Observability Simple Access Protocol is progressing toward recommended status. To support the development of compliant implementations, ESA has extended its service validation framework to include a validator for this protocol. This short presentation introduces the new Object Observability validator, accessible through the Euro-VO Registry web interface as well as through the API. A brief demonstration will showcase the validator's functionality against current services and discuss how data providers can use this resource when implementing new Object Observability endpoints.

Registry Ideas
Having recently developed a new minimal publishing registry implementation the author has a testbed for new ideas. These include

  • trialing an interface that is somewhere between OAi-PMH and RegTAP that is easier for web clients to use.
  • adding new content types to the registry data model - .e.g. Observatories, Telescopes - i.e. extracting these from ProposalDM
The purpose of the talk is to promote some discussion on some "bigger picture" ideas for the future of the registry. 		pdf 10+5 mins
Hendrik Heinl (GAVO/INAF) Simulations in the registry
At INAF I am currently working on/fighting with publishing SImulatoin data products with the VO registry. This is a short presentation of problems I ran into with SimDM. 		PDF 10+5 mins
All Discussion   15 mins
