---+ Solar Data : annotation with UCD Tags<span style="white-space: pre;"> ------------------------------------------ </span>started Spring 2021
---+++++ Participants : V. Delouille , B. Cecconi, M.Louys, add your name ...

Here we study and discuss how and why the Unified Content Descriptors vocabulary can be used and extended for catering Solar Data in various projects.
---++ *Annotation with existing UCD*

Choose a UCD for tagging metadata in different projects.

here the process is to compare the usage of a metadata keyword in the solar community and check wheter a term already present in the UCD list can be used

3 cases forseen:
   * one existing term can be used straight ahead
   * one existing term can be used , but may need some change in the UCD definition : restriction , extension , etc
   * no term exists matching the need : create a new term or a group of new terms by writing a VEP-UCD document
---+ <span style="color: #000000; font-size: small;">We are proposing to re-use the VEP documents proposed in Vocab2.0 and use them in contexts where a group of terms is proposed together and discussed . </span>
---+ <span style="color: #000000; font-size: small;">VEP= Vocabulary Enhancement Proposal</span>

Several terms that correspond to related properties can be discussed in the same VEP_UCD to keep their evolution consistent.

VEPsForUCD is the page collecting all VEP_UCD files. it records the currents VEP for UCD under discussion.

---++ *Validation of new terms*

The maintenance process defined in the Maintenance recommendation applies. See the specification [[https://ivoa.net/documents/UCDlistMaintenance/20191007/index.html][here]]

Check the status of terms discussed on the UCDListMaintenancePage.
