| Laurent Michel | 15' + 3' | Mango last step <p>After being delayed due to the MIVOT recommendation process, the MANGO data model is now a VO working draft.<br />The purpose of MANGO, which stands for MO-del for AN-notating G-eneric O-objects, is to add an<br />upper level of description to the tabular data of query responses. It allows metadata to be extended,<br />complex quantities to be reconstructed from multiple column values and properties to be linked<br />together. It also allows to specify the origin of the data.<br />I’ll give an overview of the model and the tools available to exercise it.<br />This talk is an invitation for people to contribute to the REC process.</p> |  [[%ATTACHURL%/2025-Mango-DM-UMD.pdf][pdf]]  |
| Pat Dowler | 25' + 5' | CAOM-2.5 <p>This is a status update on the WD-CAOM-2.5 standard document itself and some feedback on some VO-DML<br />related issues. We will also provide some details on the status of updating !OpenCADC implementations of the<br />model and services to the draft version.</p> <p>Note: The version in the IVOA doc repo may be be out-of-date - check the preview at <span data-mce-mark="1">https://github.com/opencadc/CAOM</span></p> |  <p> </p> [[%ATTACHURL%/WD-CAOM-2.5.pdf][pdf]]  |
