Artifacts

“Preserved” means the archive holds the bytes and their digest. “Referenced” means it holds the record of them and nothing more. The archive does not claim a holding it cannot prove.

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/a19f5ca87d3f3692ba76a1d150036121/parcels-20201-columns.json — 1761 bytes, SHA-256 a19f5ca87d3f3692…, 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.

Who publishes Parcels (2020), and under what license?

The archive accessioned it under Open Data Commons Public Domain Dedication and Licence (PDDL) 1.0 (public domain), and holds the publisher's own column dictionary verbatim rather than reworded into the archive's vocabulary — how a publisher names a column is evidence about the publisher.
