Schema-only project asking for feedback—no working implementation yet.

Strengths
  • •Addresses real fragmentation problem in SEC filing formats and cross-document queries.
  • •Open-source approach could enable standardized semantic queries across funds.
Weaknesses
  • •No tooling or implementation—just a schema specification at this stage.
  • •Financial ontology space already has FIBO and existing XBRL standards.

Post 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.
