---+ Source DM: Call For Scientific Requirements

During the spring 2018 Interop in Victoria, we had a hands-on session focused on the tools available to work with VO data models. The goal this session was to annotate data from different origins in order to make it inter-operable to eachother. The main concern expressed during this session was not related to the tools but to the lack of models for sources. <br /> <br />After some discussions, it appeared that having a global model for all missions and all archives would lead to a very complex model not usable in practice. The reason is that such a global model would have to merge all quantities of all user-cases it is supposed to cover. <br /> <br />It seemed to us more realistic to design a basic model, namely a *core-model*, with a reasonable set of quantities (ra, dec, ....) useful for all missions and to make it expendable with more<strong> specific components</strong> (e.g. parallax). So that a model aware tool could compare sources from different origins on the basis of the model components really instantiated. The data annotation process would also be simpler since only the core-model and some components of interest should be tagged.

<br /><strong>The purpose of this page is to gather requirements from people involved in different missions and archives with the goal of proposing a draft in 2019. It is to be noted that Gaia people at ESA have already presented their own model proposal which is for us a good preliminary example of what is intended. </strong>
