During the METIS meeting in May 2013, it was agreed that the relationship between Neuchâtel and GSIM should be reviewed.
After this meeting, the Neuchâtel working group met with the GIG and it was agreed that the Neuchâtel working group would bring a proposal about how to harmonise/ align the two models at the end of July. After a number of discussions, the Neuchâtel working group would like to put forward the following proposal to the GIG.
Neuchâtel and GSIM working together: A two part proposal
1) It is proposed that Neuchâtel becomes part of GSIM. This means that the terminology used in GSIM and Neuchâtel is changed so that there is complete alignment. As such it is proposed that changes are made to the GSIM Specificiation layer in terms of objects, definitions, attributes and relationships (the proposed changes are detailed below).
2) Neuchâtel contains some excellent detail that is very useful to people implementing it. This level of detail is too detailed for the GSIM Specification layer (the current most detailed level of GSIM), but is necessary for those working with classifications. In addition to the changes made to the GSIM Specification Layer, an annex will be written which includes this finer level of detail.
The annex will be able to stand in its own right as a document. It will align completely to the GSIM Specification Layer and will reuse / update much of the content of the current Neuchâtel document. The creation of this document will be the responsibility of the Neuchâtel working group.
The Neuchâtel working group asks that the GIG consider their proposed changes to the classification objects in GSIM.
The proposal is outlined in the diagrams and tables below. Please note that the attributes and relationships pertaining to classification index entries is still being fine tuned by the group.
