DM Session 1: Updates

Live Notes: https://yopad.eu/p/IVOA_June25_DM1

Tuesday June 3 @11:00 EDT: Room 2309
Speaker	Time	Title	Material
Laurent Michel	15' + 3'	Mango last step After being delayed due to the MIVOT recommendation process, the MANGO data model is now a VO working draft. The purpose of MANGO, which stands for MO-del for AN-notating G-eneric O-objects, is to add an upper level of description to the tabular data of query responses. It allows metadata to be extended, complex quantities to be reconstructed from multiple column values and properties to be linked together. It also allows to specify the origin of the data. I’ll give an overview of the model and the tools available to exercise it. This talk is an invitation for people to contribute to the REC process.	pdf
Pat Dowler	25' + 5'	CAOM-2.5 This is a status update on the WD-CAOM-2.5 standard document itself and some feedback on some VO-DML related issues. We will also provide some details on the status of updating OpenCADC implementations of the model and services to the draft version. Note: The version in the IVOA doc repo may be be out-of-date - check the preview at https://github.com/opencadc/CAOM	pdf
