|  *Speaker*  |  *Title*  |  *Abstract*  |  *Time*  |  *Material*  |
|  Ivan Brossard<br /><i>(in person)</i>  | Implementing Datalink in !VizieR | !VizieR is a web service that provides access to thousands of catalogues of<br />astronomical data. Some of these catalogues have associated data, like spectra<br />or images. Although it’s easy accessing the associated data from the HTML page,<br />it’s impossible accessing the data from a query outside the HTML form. In order<br />to circumvent this issue, we added an option to display a Datalink column, which<br />can redirect to the associated data. We used the Datalink standard described by<br />DAL ( [[https://www.ivoa.net/documents/DataLink/20231215/REC-DataLink-1.1.html][REC-DataLink-1.1]]). | 15'+5' |  <p> [[%ATTACHURL%/Datalink_IVOA_gorlitz.pdf][pdf]]</p> <p> [[%ATTACHURL%/Datalink_IVOA_gorlitz.odp][odp]]</p>  |
|  Nathan Barloy<br /><i>(in person)</i>  | Creating a tool to automatically generate<br />an !ObsCore Table from a FITS collection | To ensure we have more FAIR data for Open Science at the CDS, we want to<br />have more ObsCore tables associated with our catalogs. That is why we are<br />creating a Python library capable of extracting information from a FITS collection,<br />with additional user data.  | 15'+5' |  [[%ATTACHURL%/presentationv2.pdf][pdf]]  |
|  Jose Osinde Lopez<br /><i>(in person)</i>  | ESDC TAP Stateless Follow-up | The presentation outlined key challenges, including performance issues and <br />the need to share session information across multiple instances. We highlighted<br />the strengths of the new approach as improved robustness and scalability. <br />Finally, we noted that certain areas, such as database performance, remain <br />outside this solution’s scope and will require separate optimization, <br />potentially through MMP database technologies.  | 15'+5' |  <p><a href="https://wiki.ivoa.net/internal/IVOA/InterOpNov2025DAL/ESAC_TAP_IVOA_Nov2025.pptx" title="ESAC TAP (pptx)">pptx</a></p> <p><a href="https://wiki.ivoa.net/internal/IVOA/InterOpNov2025DAL/ESAC_TAP_IVOA_Nov2025.pdf" title="ESAC TAP (pdf)">pdf</a></p>  |
|  Marco Molinaro<br /><i>(in person)</i>  | ConeSearch -1.1 status | Recap of the status of the ConeSearch 1.1 working draft, with discussion points<br />that are still standing, and a (personal?) view of the 2.0 relationship. | 15'+5' |  [[%ATTACHURL%/ConeSearch11_Molinaro_Goerlitz.pdf][pdf]]  |
