---++ Claudia Martens:  IVOA resources in B2Find and OpenAire via DataCite
</div> <div id="magicdomid9">B2Find search portal - search and ingest research metadata across various scientific communities.</div> <div id="magicdomid10">One of harvesting methods is OAI-PMH, which works with the IVOA registries</div> <div id="magicdomid11">
   * schema mapping: DataCite (old), DublinCore, other standards
</div> <div id="magicdomid12">
   * schema mapping EUDAT Core: experimental format through GAVO registry, includes instrument, etc. Markus is involved in using the EUDAT core metadata, it's a job in progress. Specially for coverage for time, and sky coverage. instrument and resourcetype is now inside
   * système no-sql with facet
   * Current portal: [[http://b2find.eudat.eu/dataset?groups=ivoa]] .New B2Find site coming June 2022 (or later)
</div> <div id="magicdomid13">OpenAire: another EU-wide search project; papers, 'research output'</div> <div id="magicdomid14">
   * Everything in B2Find published in OAI with various metadata prefixes; harvested to OpenAire as DataCite
   * OpenAire use multiple data id not only DOI as Datacite, but it's the one we already provide (via GAVO)
</div> <div id="magicdomid15">
   * Some IVOA metadata lost in translation; can be improved when they support EUDAT Core?
</div> <div id="magicdomid16">Do IVOA records count as 'in' European Open Science Cloud because GAVO registry -&gt; B2Find -&gt; OpenAire?</div> <div id="magicdomid17">
   * Search Portal (yes), Marketplace (EOSC members have no relevant services), not working well.
</div> <div id="magicdomid18">
   * Update in September: may make this more useful?
</div> <div id="magicdomid19">
   * FAIRCORE 4 EOSC: proposal to expand service definitions, will this make ours usable?
</div> <div id="magicdomid20">
   * So, yes, but groups becoming formal 'EOSC Provider' to onboard services and products would improve inclusion in upcoming projects. How do we do that?
</div> <div id="magicdomid22"></div>

<div id="magicdomid25">Questions/comments:</div> <div id="magicdomid26">   * Call from Markus to add temporal coverage to registry records - to pull into these searches</div> <div id="magicdomid27">   * Mark Allen: working with EOSC policy and other EU projects: how do we onboard IVOA / registry as a whole? Some projects and data services already in (SIMBAD), but how do we do this as a whole?</div> <div id="magicdomid28">   * Tess Jaffe: similar to some NASA open science plans?</div> <div id="magicdomid31">
---++ Markus Demleitner: RegTAP 1.2
</div> <div id="magicdomid33">RegTAP 1.2 Working Draft soon: STC Tables and GloTS replacements</div> <div id="magicdomid35">STC tables:</div> <div id="magicdomid36">
   * Example implementation at: dc.g-vo.org/tap
</div> <div id="magicdomid37">
   * We need more implementations before standard! And this means MOC support!
</div> <div id="magicdomid39">MOC takeup issues:</div> <div id="magicdomid40">
   *   MOC in ADQL (not in 2.1?)
</div> <div id="magicdomid41">
   *   MOC in VOTable (this goes in DALI -- is in DALI 1.2 per Pat Dowler)
</div> <div id="magicdomid42">
   *   MOC in DB: we have these in pgSphere. what about SQL Server?
</div>

Use of Utype in table metadata to dicover tap with specific datamdel (rr, epn-tap, line ...)
<div id="magicdomid43"></div> <div id="magicdomid45">Replacing GloTS (evolution of Glots used for finding services, harvest /tables from tap services):</div> <div id="magicdomid46">
   * Can we offer a view of TAP-queryable tables?
   * Needs to filter duplicate tables (from tableset of TAP service and from resources with aux TAP capabilities)
</div> <div id="magicdomid48">
   * proposal: view server side? requires UNION, not supported in ADQL for client side
</div> <div id="magicdomid50">
   * Open problems:
      * Some services do not maintain their tablesets in the registry (problem of maintaining tableset on registry resource, difficult if you don't have an integrated publishing registry)
</div> <div id="magicdomid51">
   * 
      * tableset not 100% well defined - can contain output tables we want to keep out of tap_table (???)
</div> <div id="magicdomid52">
   * 
      * There's no way to get originating resource
</div> <div id="magicdomid54">Questions/comments:</div> <div id="magicdomid55">
   *   Dower: See the sql/etc for the view build?
</div> <div id="magicdomid59">
---++ Hendrik Heinl: Documentation and Tutorials in the Registry
</div> <div id="magicdomid61">From Edu note to TextRegExt in RegTAP?</div> <div id="magicdomid62">Based on Edu note: https://ivoa.net/documents/Notes/EDU/index.html </div> <div id="magicdomid64">Use cases: Curated tutorial collections</div> <div id="magicdomid65">
   * There is new demand 
</div> <div id="magicdomid66">
   * Especially how do we find tutorials on how to publish?
</div> <div id="magicdomid67">
   * These become outdated - how can we track this usefully?
</div> <div id="magicdomid69">Proposal: TextRegExt - from Chapter 2 of the Note</div> <div id="magicdomid71">One rendering of this data: https://dc.g-vo.org/VOTT </div>

<div id="magicdomid73">Questions/Comments:</div> <div id="magicdomid74">
   *   Janet Evans: Can harvest these all into a web collection
</div> <div id="magicdomid75">
   *   How do we curate these to be useful and validated?
</div> <div id="magicdomid76">
   *    Markus: sort by contentlevel, validation tags, author, etc
</div> <div id="magicdomid79">
---++ Chloé Azria: Registering EPN-TAP services using DaCHS
</div> <div id="magicdomid81">Work translating planetary schema/vocabulary (EPN Core) to TAP/resources tags</div> <div id="magicdomid82">UAT keyword subjects (https://astrothesaurus.org)</div> <div id="magicdomid83">Provenance issues: only one naming authority, several servers</div> <div id="magicdomid84">Findability issues with first pass of resource names/titles</div> <div id="magicdomid85">
   * don't find own services w/default TOPCAT inclusion
   * problem discovering service EPN-TAP as collection as they have each one specific subject. The more convenient client is TOPCAT, when venus is a subject in VODataResource, it's not visible in the query
   * Also a Topcat feature, when you select a resource inside a TAP VODataService topcat select the first table alphabetically not the one dedicated to the selected ressource
</div> <div id="magicdomid86">
   * debugging with TOPCAT / ADQL
</div> <div id="magicdomid88">Questions/Comments:</div> <div id="magicdomid89">
   *   Mark Taylor: will follow up (with Markus) on TOPCAT findability, what tags show up where?
</div> <div id="magicdomid90">
   * Claudia: Can we rely on everyone using UAT for subjects?
</div> <div id="magicdomid91">
   * Markus / Theresa / Chloe: Not technically required but we are all working on it!
</div> <div id="magicdomid92">
   * Baptiste: the issues with search are also in TAP Handle - this may be the CatalogResource type?
</div> <div id="magicdomid93">
   * Markus: pyvo pull request for registry search - way to fix findability, maybe?
</div> <div id="magicdomid94"> More info on that: https://blog.g-vo.org/towards-data-discovery-in-pyvo.html </div> <div id="magicdomid95">  </div> <div id="magicdomid96">  </div> <div id="magicdomid97"> </div>
