In the first week of June 2019 PDOK and Geonovum organized a week of experiments on WFS 3 (formally called OGC API Features now), called (in Dutch): “WFS 3 werkweek”. The goal of this week was to acquire and share knowledge and experiences on WFS 3. Several Dutch organizations participated in the experiments and closing session.

This document summarizes the lessons learned from this week: what works well, what is unclear or work to be done and what (possible) issues have been identified when working with OGC API Features.
