Update approach to using OpenCorporates identifiers for sub-national jurisdictions about register

[kd-ods]

Working theory would be the jurisdiction code is {country-code}_{region-code}

Jurisdiction codes are always likely to have those two parts, but I think any ingester looking at a jurisdiction code field will need to parse various separators. It looks like both OpenCoroporates and org-id use the underscore separator. But subdivision codes in ISO 3166-2 start with the country code and then append a two letter region code, with a hyphen separator. For example. 'CA-AB' for Alberta, Canada. All Canada's subdivision codes are here.

We say in BODS that Jurisdiction.code is "The 2-letter country code (ISO 3166-1) or the subdivision code (ISO 3166-2) for the jurisdiction". See schema ref So the mongo jurisdiction_code should probably do likewise.

If this service (https://beta.canadasbusinessregistries.ca/about) improved to include more Canadian registers and to have an API, then it could be useful for resolving ca codes. Unfortunately, it's rather lacking at the moment.
