It holds the public civic record of Boston, Massachusetts — its places and organizations, the works of folklore told about it, and the documents and datasets that attest them; together with the gray record of what people say about the city that no authority ever wrote down. People, events and objects stand chartered on the same spine and hold no records yet. Every record carries a stable identifier, a canonical address, a full provenance chain, and its version history. Every record resolves as a page for a person and as JSON for a machine.","email":"archive@boston.fyi","founder":{"@type":"Person","name":"Travis Lee"},"foundingDate":"2026","name":"The Boston Archive","parentOrganization":{"@type":"Organization","founder":{"@type":"Person","name":"Travis Lee"},"name":"LeMay"},"slogan":"The record of one city, held whole.","url":"https://boston.fyi"},{"@id":"https://boston.fyi/#website","@type":"WebSite","conformsTo":"https://boston.fyi/standards/csts-01-reference-profile","inLanguage":"en","name":"The Boston Archive","potentialAction":{"@type":"SearchAction","query-input":"required name=search_term_string","target":{"@type":"EntryPoint","urlTemplate":"https://boston.fyi/ask?q={search_term_string}"}},"publisher":{"@id":"https://boston.fyi/#archive"},"url":"https://boston.fyi"},{"@id":"https://boston.fyi/document/atlas-of-the-city-of-boston-boston-proper-and-back-bay#provenance","@type":"CreativeWork","additionalProperty":[{"@type":"PropertyValue","name":"sourceCollection","value":"Boston Public Library digital collections"},{"@type":"PropertyValue","name":"licenseName","value":"No known copyright restrictions"},{"@type":"PropertyValue","name":"licenseOpenness","value":"public_domain"},{"@type":"PropertyValue","name":"retrievedAt","value":"2026-09-05T12:25:50.973235+00:00"},{"@type":"PropertyValue","name":"transformCount","value":5}],"creator":{"@type":"Organization","name":"Boston Public Library digital collections"},"creditText":"Boston Public Library","dateCreated":"2026-09-05T12:25:50.973235+00:00","isBasedOn":"https://ark.digitalcommonwealth.org/ark:/50959/9g54z635h","license":"https://www.digitalcommonwealth.org/","name":"Provenance of Atlas of the city of Boston, Boston proper and Back Bay"},{"@id":"https://boston.fyi/document/atlas-of-the-city-of-boston-boston-proper-and-back-bay","@type":"DigitalDocument","additionalProperty":[{"@type":"PropertyValue","name":"recordType","value":"Document"},{"@type":"PropertyValue","name":"documentType","value":"map"},{"@type":"PropertyValue","description":"preserved = the archive holds the bytes and their digest; referenced = the archive holds the metadata only","name":"preservation","value":"preserved"},{"@type":"PropertyValue","description":"digest of the bytes as retrieved, before any transform","name":"sha256","value":"aed9c8684dbd7f57cf1e21aeb0aec955f98ec6d2446d1c0b62731ccb36a6ebf9"}],"conformsTo":"https://boston.fyi/standards/csts-01-reference-profile","contentSize":"225691","dateCreated":"2026-09-05T12:26:06.875798+00:00","dateModified":"2026-09-05T12:26:06.875798+00:00","description":"Atlas of the city of Boston, Boston proper and Back Bay, 1922 — Real property--Massachusetts--Boston--Maps, Landowners--Massachusetts--Boston--Maps, Beacon Hill (Boston, Mass.)--Maps.
