This document is related to the document MFF-BAS API Design Guidelines. Although the latter is based on the API strategy for the Dutch Government, it did not provide a URI strategy. Therefore, the Working Group API Strategy made the decision to establish agreements regarding the use and application of URIs themselves. Written by several colleagues in the sector, and approved by the Architecture Council and general members’ meeting (ALV) of MFF BAS. I’m pleased to have played a part in its creation. The result of this effort is the present document. This document is written in Dutch (visible or downloadable below).
