It contains the ObsCore section (6.2) of the HEIG IVOA Note and then Ian’s table from his Interop presentation. From there we can move it toward the document we need for June.</div><div><br></div><div>The ObsCore Extension was a topic at the TCG meeting this week, so we’re working one of the topics the IVOA considers high priority. Marco suggested a Plenary session at the College Park meeting. I reported that we had a good meeting with Radio and TimeDomain in Feb and were working meet the ‘have a doc by the Interop’ schedule.</div><div><br></div><div>I’ve been thinking how to support input to the process, and my idea was to create a Google table where folks can share their ideas/suggestions for the Obscore extension that would support their waveband beyond those identified so far. Then we can meet as a group, discuss, and decide which move up to the Note. I also don’t want folks to be shy about making contributions … the more we have the better. It will ensure healthy conversation and we’ll made a decision on each keyword. The thing to remember is that these keywords are for data discovery of your data in the VO.</div><div><br></div><div>Here’s pointers info on ObsCore related docs (I also added it to the HEIG wiki page):</div><div><h5 style="padding: 0.25em 10px; margin: 1.25em -10px 0.35em; line-height: 1em; font-size: 15.015px; border-width: 0px 0px 1px; border-style: solid; height: auto; color: rgb(99, 0, 0); border-color: rgb(226, 226, 226); font-family: arial, verdana, sans-serif;"><strong>Priority 1 - HEIG <a class="twikiLink" href="https://wiki.ivoa.net/twiki/bin/view/IVOA/ObsCore" style="text-decoration: none; color: rgb(99, 0, 0); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">ObsCore</a> Extension - 2025</strong></h5><ul style="margin-top: 0px; font-family: arial, verdana, sans-serif; font-size: 13.649999px;"><li><a href="https://github.com/ivoa/HighEnergyObsCoreExt" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">HighEnergyObsCoreExt</a> - <a class="twikiLink" href="https://wiki.ivoa.net/twiki/bin/view/IVOA/GitHub" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">GitHub</a> repo for the project</li><li>Pointer to Google Doc for <a class="twikiLink" href="https://wiki.ivoa.net/twiki/bin/view/IVOA/ObsCore" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">ObsCore</a> Extension inputs/talking points - <a href="https://docs.google.com/spreadsheets/d/16e0mWWD5hn6fLYQFf7SqD4crJvGlroV44Zs3uRCZqGM/edit?usp=sharing" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">https://docs.google.com/spreadsheets/d/16e0mWWD5hn6fLYQFf7SqD4crJvGlroV44Zs3uRCZqGM/edit?usp=sharing</a></li><li>Obscore v1.1 Standard (2017): <a href="https://www.ivoa.net/documents/ObsCore/" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">https://www.ivoa.net/documents/ObsCore/</a></li><li>Radio extension proposal (Nov24): <a href="https://github.com/ivoa-std/ObsCoreExtensionForRadioData" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">https://github.com/ivoa-std/ObsCoreExtensionForRadioData</a></li><li>Time extension proposal (Jul24): <a href="https://github.com/ivoa-std/ObscoreTimeExtension?tab=readme-ov-file" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">https://github.com/ivoa-std/ObscoreTimeExtension</a></li><li>Common Archive Observation Model (CAOM) Sep24 draft: <a href="https://www.ivoa.net/documents/CAOM/index.html" target="_blank" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">https://www.ivoa.net/documents/CAOM/index.html</a></li><li>X-ray Obscore working extension table (Jan25) - <a href="https://wiki.ivoa.net/internal/IVOA/HEIG_Winter25/HEIG_obscore_summary.pdf" target="_top" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">HEIG_obscore_summary.pdf</a>, I Evans (from Malta Interop)</li><li>Analysis of Obscore for the VHE (May24) - <a href="https://wiki.ivoa.net/internal/IVOA/InterOpMay2024DM/2024-05-21_ObsCore_access_to_HESS_public_data_-_Servillat.pdf" target="_top" style="text-decoration: none; color: rgb(88, 67, 139); border-color: rgb(88, 67, 139); border-style: none none dotted; border-width: 1px;">IVOA Sydney, M.
