MODAVIS Pipe Organ Dataset (POD) 1.6.0

MODAVIS Pipe Organ Dataset (POD) 1.6.0 provides source-attributed data for research on pipe organs, builders and other actors, specifications, documented histories, places, literature, media references, scores and virtual instruments. It consolidates processing corrections and research additions after the POD 1.5.5 source corpus and the 1.5.6 semantic exports. The corpus retains 215,769 organs, 11,778 actors, 12,314 structured names, 203,831 places, 897 virtual instruments, 25 source collections and 230,881 source memberships. Canonical identifiers and alias targets are unchanged. There are 218,116 specification accounts, 764,204 technical facts and 439,077 documented events. Structured stop accounts now cover 143,880 organs, compared with 87,798 in the baseline. The 3,604,579 public stop occurrences include 1,605,265 recovered occurrences; these are source-account rows, not a total of unique physical stops. Builder processing separates supported participants, roles, narrative and technical facts while retaining original wording and provenance. Linked builder assertions increased from 177,074 to 206,970. There remain 100,589 unlinked assertions. Event correspondence removes duplicate representations where the source evidence establishes equivalence. Dated specification accounts increased from 4,546 to 7,037; a source listing does not establish present condition. Coordinate qualifications and administrative evidence are retained explicitly. The package includes the public-core SQLite database, Lite/OrgMap/OrgRec convenience databases, the inherited 1.5.5 identifier ledger, a PostgreSQL 15 projection and portable research read models. Research resources support evidence-backed actor networks, comparison of specification accounts, chronology and stop-name exploration. An attributed terminology inventory contains 6,228,856 records across 31 field families. Fourteen candidate concepts and 39 lexical rules match 565,475 occurrences; these mappings do not establish endorsed organological classifications. Complete N-Triples distributions provide MODAVIS, CIDOC CRM, Europeana Data Model and Polifonia Organs mappings. The 1,554 parts contain 686,141,978 statements across overlapping profiles. DCAT/VoID descriptions, a public source-projection schema, counts, checksums, methods and a quantified changelog are included. The smaller JSONL files are catalogue summaries. EDM remains a mapping profile, without a claim of Europeana ingestion. Acceptance includes exact candidate and research replay, full semantic parsing and coverage checks, fresh PostgreSQL restore, and local Navigator checks in desktop and narrow-screen browsers. POD 1.6.0 is also available through the deployed MODAVIS Navigator at https://navigator.modavis.org. The application and dataset have independent version numbers. Historical exports 1.5.5 and 1.5.6 retain their original source bindings. Coverage limitations remain explicit: 203,257 organs have one supporting source; many historical accounts lack an established configuration date; 581 represented-organ relationships remain unresolved; and the 461,738 media references depend on external delivery. No missing stoplist, actor identity or precise location is invented. Original source attribution and third-party rights remain applicable. Raw source collections, source database copies, private operational records, credentials and media binaries are excluded. Software/deployment archives and the independently versioned OMARO reference are maintained separately.
