Request for feedback on new L22 terms about l22 HOT 2 CLOSED

I seem to remember a discussion on these concepts during a VMG meeting and from what I remember these seem to be what I would expect in L22 linked to a colonisation substrate L05 entry. I think this was being set up by Lou, but not sure how far it got.

I don't like the word 'unknown' in concept labels- I'd use the description to explain the generic nature of the concept. I also don't like abbreviations in labels - the purpose of CODALT is to expose abbreviations to searches. For example I'd have:

Polyvinyl chloride pipe colonisation substrate
PVC pipe substrate
Any object placed in the marine environment for attachment of organisms that is a hollow cylinder with open ends made from the plastic polyvinyl chloride (PVC).

for codnam, codalt and description.

from l22.

We have now finalised the following terms, which will appear on the NVS overnight:

Custom-made Lexan plastic 6-plate settlement panel (http://vocab.nerc.ac.uk/collection/L22/current/TOOL1413/)
