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 City of Boston Managed Streets, and under what license?

Boston Maps publishes it. 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.
