Description

Working on a schema for joining SEC fund filings across documents. The core problem: these filings describe the same fund in different formats and no standard exists for cross-document semantic queries.Interested in feedback on the ontology design — especially from anyone working with fund data, XBRL, or FIBO.

Could you build this?

Partial The schema or ontology definition itself is text/JSON-LD, but creating a comprehensive, accurate cross-document SEC fund ontology requires deep specialized domain knowledge in XBRL, SEC EDGAR filing taxonomies, and mutual fund accounting.

What it would actually take: Building an SEC fund ontology requires modeling entity structures (registrants, series, classes, CIK numbers) against various filings (N-PORT, N-CEN, N-1A, 13F) in OWL/RDF or Pydantic/JSON Schema. The difficult aspect is resolving discordant historical identifiers, cross-document entity deduplication, and parsing nested XML/XBRL schemas. Domain expertise in US securities law and regulatory reporting formats is essential to validate semantic relationships.
