DB: Common keywords
Goal
Define a common vocabulary to describe observations within the database.
Status Quo
Currently, the documents in the tables gris_observations, lars_observations etc. are made up of fields named after the keywords occurring in the Headers of the respective FITS files. In order to make querying and the development of the webpage easier, we need a common vocabulary.
The following points need to be considered:
- The keywords need to use common units for all instruments
- The definition needs to be written down somewhere, in a eloquent format
- The keywords should be mappable to the minimum requirements provided by IVOA OBS-CORE (Pages 15 and 16)
The seemingly best approach would be to use the Solarnet recommendations wherever possible. This allows using a established standard with as little self defined keywords as possible.
