LCC_ — Including all subdivision codes in a single ontology is not workable - they should be separated into distinct namespaces / ontologies for ease of use

Currently, the set of subdivision codes available in LCC (which only reflect North America) are all in one namespace and ontology. They should be split into an ontology per country containing the relevant regions for ease of use and maintenance purposes.

Including all subdivision codes in a single ontology is not workable - they should be separated into distinct namespaces / ontologies for ease of use

Based on review of the number of countries who have submitted subdivision codes to the U.N. which are codified in ISO 3166-2, the FTF has made the following changes:

1. Retained the top level ISO 3166-2 ontology, but only for the purposes of defining the code set and one necessary geographic region kind (Territory) for use in multiple region codes ontologies.

2. Created a submodule within the LCC/Countries module for Regions

3. Automated the generation of all of the region codes contained in the latest publication of ISO 3166-2 (i.e., as of July 20, 2017), with one ontology per region. The resulting URI for each ontology takes the form: http://www.omg.org/spec/LCC/Countries/Regions/ISO3166-2-SubdivisionCodes-<xx>/, where <xx> represents the alpha 2 ISO 3166-1 code for the country or other region for which subdivision codes are available.

The complete list of normative ISO3166-2 region-specific ontologies is included in a new annex B (normative) which lists the machine readable files, rather than listing them on the cover of the specification, due to the number of files. The machine readable files are attached to the report rather than to this issue resolution.
