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.

model and services to the draft version.
