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.

| 4 | externalize-boundary | The boundary left the inline page graph and became two preserved holdings: the exact coordinates at /asset/8c5f8c06fa08459c827d89a462d0a7b0/board-of-trade-building.geojson and a static map rendered server-side at /asset/1870a9f9aaa83410abee9ec5b9722e02/board-of-trade-building.svg. The stored geometry is unchanged; the record graph now addresses it instead of carrying it. | archive-ingest 0.1.0 |
