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

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 .

VEP= Vocabulary Enhancement Proposal

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 here

Check the status of terms discussed on the UCDListMaintenancePage.
