Ask a city for the technical record of what it shares, and you may learn that it does not have one. In one records response, a city explained that it holds no interface specifications, field mapping, or data translation records, because those are created and kept by LexisNexis or the software vendor, not the city.
That gap is structural, not accidental. The data a city cares about lives in its records management system (RMS), its computer-aided dispatch system (CAD), or its jail management system (JMS), and each of those is run by a private company, not the city: LETG, Motorola, Tyler Technologies, CentralSquare, Spillman, and the like. The LexisNexis feed is then built between two of those private vendors. The city is effectively asking one third party to integrate with another, so the technical side of the arrangement (what fields map where, how the translation works, what actually goes out the door) is something Motorola is working out with LexisNexis, or CentralSquare with LexisNexis, and so on. The detail never sits inside city hall, because no part of it was ever built there.
The gap compounds the renewal problem. The contract renews itself, so there is no recurring vote, and the configuration lives with the vendor, so there is no local file. Meanwhile, at least one agency asserted in a records response that AVCC contributions could not be restricted at all.1 Another agency, Oklahoma City, had already negotiated exactly that restriction. The claim and the counterexample sit in the public record at the same time.
