With the exception of mappings between the ICES Platform codes on the NVS as collection C17 and in the ICES vocabualry collections which are managed via a very formal process, other mappings between NVS and ICES concepts are being worked on on an ad-hoc basis for the time being. If required, please request new mappings by raising an issue ticket mentioning the NVS source and ICES target vocabulary and term.
