*DM Running meeting /03/02/2022*
<div id="magicdomid4">Participants: 11</div> <div id="magicdomid7">Laurent Michel, Jesus Salgado, Marco Molinaro, Francois Bonnarel, Janet Evans, Gerard Lemson,</div> <div id="magicdomid8">Mark Cresitello-Dittmar, Tom Donaldson, Paul Harrison, Mireille Louys, Mathieu Servillat</div> <div id="magicdomid11"> *Agenda* </div> <div id="magicdomid12">

   * Ongoing work status
</div> <div id="magicdomid13">
   * ADASS BOF
</div> <div id="magicdomid15">LM description of the ADASS BoF on TAP and DMS</div> <div id="magicdomid16">Different areas covered from presentation, annotation, browsing hierarchical data, stroting complex objects in TAP and query languages issues</div> <div id="magicdomid18">Two propotypes presented</div> <div id="magicdomid19">All the discussion will be described into the ADASS proceedings</div> <div id="magicdomid21">GL: Effort developed on this area could be also interesting on mapping simulations on TAP</div> <div id="magicdomid22">LM: Yes, this is similar to the provenance mapping presented by FB</div> <div id="magicdomid23">GL: There are java classes and it is a relational approach</div> <div id="magicdomid24">PH: I am progressing along these lines on code generation. If there is a VO/DML repository, a plugin could be written. Current work is in the line of mapping data to models</div> <div id="magicdomid41">LM: the conclusion is that we need to use TAP. Discussion to continue in the list</div> <div id="magicdomid55">
   * PhotDM
</div> <div id="magicdomid68">Mireille presenting on the photDM 1.1</div> <div id="magicdomid69">Review the VO/DML work in Modelio</div> <div id="magicdomid70">And the pages with the documentation</div> <div id="magicdomid71">[[PhotDMv1-1][https://wiki.ivoa.net/twiki/bin/view/IVOA/PhotDMv1-1]]</div> <div id="magicdomid72">ML showing the xml file and the html (human readable) file</div> <div id="magicdomid102">New model is almost fully compatible with current serializations</div> <div id="magicdomid155">GL: Some formating issues on the html with the css and the generated png not present</div> <div id="magicdomid191">ML: If you provide support we could solve it</div> <div id="magicdomid230">GL: Also there is a concept of preamble that could be used to be included automatically</div> <div id="magicdomid110">
   * Meas/Coords
</div> <div id="magicdomid364">Mark CD: Presentation of DM use cases implementations and also some Jupyter notebooks that make use of this models</div> <div id="magicdomid416">Once this is approved, no major extra steps to start standardization</div> <div id="magicdomid478">JE: Is this model ready for the next step?</div> <div id="magicdomid534">LM: In principle yes as this is reused. One thing to test if the model is ready for interoperability.</div> <div id="magicdomid669">TD: This is something that is something to be done and doable. Problem about versioning of mapping on data model. Probably not needed to have full sync but it is sometimes confusing to find the versioning link</div> <div id="magicdomid699">FB: Is there a future for transform DM?</div> <div id="magicdomid727">Mark CD: It should be the next to be worked out</div> <div id="magicdomid1192">
   * Mapping Syntax, Mapping Library and Model Validation
</div> <div id="magicdomid762">LM: Presentation on the work done on the mapping syntax</div> <div id="magicdomid794">Work documented into the ModelInstanceInVot into the IVOA github</div> <div id="magicdomid866">Presentation of the new VOTable strucutre including the Resource Meta that contains pure XML with the VODML container</div> <div id="magicdomid922">That includes: Report (on the mapping process), model, globals and templates</div> <div id="magicdomid940">Three group of elements:</div> <div id="magicdomid952">- Data Mapping</div> <div id="magicdomid966">- Data Referencing</div> <div id="magicdomid981">- Data Filtering</div> <div id="magicdomid1000">Work done based on Unit tests</div> <div id="magicdomid1073">One problem peding on element dm-mapping: tag. Support from schema experts requested</div> <div id="magicdomid1092">Python Client code being developed</div> <div id="magicdomid1196">From a XML DM serialization, a JSON serialization, Meas/Coords instances. PhotDM instance and other lib instances can be generated</div> <div id="magicdomid1251">Example with an astropy parser is able to get SkyCoords and other magnitudes from it</div> <div id="magicdomid1349">Live demostration of the jupyter notebook creating a model viewer and extracting metadata like Sky Coord</div> <div id="magicdomid1405">TD: This is fantastic. Volunteer to help on the astropy workflow to include it</div> <div id="magicdomid1444">MM: This is a way to prove validation and also to test inteoperability</div> <div id="magicdomid1532">Mark DM: This only proves validation partially, based on the point that astropy can be used but not in all the areas</div> <div id="magicdomid1563">LM: But this implies consistency on the model</div>
