Here is a summary of the post:
The [Multilingual Zotero (MLZ)] styles rely on a urn:lex-like scheme for specifying the jurisdiction of primary legal materials. We will need to have at least a minimal set of jurisdction codes in place for the styles to be functional. The scheme to be used for this purpose is the subject of this post.
URN:LEX is an international standard for legal identifiers, in the form of Uniform Resource Names (URNs).
Multilingual Zotero is an unofficial “fork” of the Zotero open source citation management software.
Professor Bennett’s post includes examples.
