Column dictionary

The publisher's own dictionary, preserved verbatim. The archive does not reword a schema into its own vocabulary — how the publisher named a column is evidence about the publisher.

The complete dictionary, exactly as the publisher words it, is served as its own holding at /asset/e68a0cb6207bcee28451d05c804fdc2d/boston-police-department-fio-columns.json — 1634 bytes, SHA-256 e68a0cb6207bcee2…, under Open Data Commons Public Domain Dedication and Licence (PDDL) 1.0.

Questions this record answers

Each answer is composed only from fields this record carries, and names the attestation for what it says. A question the record cannot answer from its own attested content is not asked here. Where a boundary is described as official it was promulgated by an authority with the power to draw it and is not amended by anything on the vernacular layer; where it is described as vernacular it is held by attestation alone and amends no official boundary.
