Add calibration level definition

[lmichel]

This vocabulary is based on the calibration levels as defined in Obcore1.1.

• Its purpose is to replace the MANGO literal enumeration for the calibration level of physical properties.
• Calibration-level vocabulary has one root which is specific for Obscore.
• It might be extended whith levels defined in other standards (EPN-TAP2 CODMAC PSA NASA PDS).
• The equivalences between these are detailed in EPN-AP 2.0 section 2.1.2.

I'm happy with having a vocabulary for this series of terms.

I would rather name it "processing-level", since the obscore-enhanced and obscore-analysis are similar to the 'reprojected' and 'derived' data processing levels that can be found elsewhere.

My main question is about having an obscore-level main concept/class. Does this mean that we will have other roots (like those mentioned in the readme?) and link them within the vocabulary?

I'll update the vocab.conf file and approve with preliminary status.

• calibration-levelhas been renamed as processing-level
• Typos corrected
• README updated accordingly

Yes, we might consider having other roots since processing levels are used in different contexts. The idea is to set then cross links between different words having the same meaning. This does not prevent to merge at some point these different words into a common standard.

I agree it's a should be a class vocabulary. I already updated the vocabs.conf file, so we can merge I think
