Technical note
Sharing data between agencies without copying everything
Key takeaways
- The template agreement turns from-scratch negotiation into form-filling — weeks instead of months.
- The use chooses the pattern: query for the case, governed batch for the population, space for the domain. The full copy is not a pattern: it is the error.
- The subject-consultable query log turns interoperability from threat into right.
- The termination section is the one nobody writes and everybody pays for: certified deletion or return.
- With template and platform, a new exchange fits in sixty days — the route is broken down step by step.
Every government data exchange is negotiated from scratch and ends in one of two pathologies: the full copy "just in case" or the request that never happens. A ten-section template agreement, three technical patterns, and a sixty-day route.
