The Hedge Fund Regulation (HFR) ontologies are an extension of the Fund Regulation (FR) and Financial Regulation Ontologies (FRO).
FRO was a 2017 legacy project that is no longer updated and supported, and the base directory, https://hedgefundontology.com/hfr/, is no longer live on the web.
However, you can download a ZIP directory of the RDF/OWL Turtle files.
The swim lane diagram shows the include tree for Hedge Fund Reasoning.
To the left are the Ontology Layers.
- An upper ontology (aka top-level ontology or foundation ontology) is an ontology that describes very general concepts that are the same across all knowledge domains. Well-known core ontologies are BFO, GFO, DOLCE, SUMO, and Dublin Core. (Wikipedia)
FIBO and LKIF don’t import Upper Ontologies. They define general concepts like dates, relationships, and roles themselves. - The goal of a core ontology is to provide a global and extensible model into which data originating from distinct sources can be mapped and integrated. (Doerr, Hunter, Lagoze)
The core ontology applies to a specific domain, such as biology, medical, Legal, and Finance. LIKIF and FIBO cover both the Upper and Core ontology layers. The Financial Regulation Ontology aligns and extends the Legal and Finance reference ontologies; thus, FinRegOnt is in the Core Layer. - The Operational Ontology implements a core ontology and is specific enough to hold source data. Both Fund and Hedge Fund Regulation are operational ontologies for the finance sub-domain of investment management. The Hedge Fund Regulation ontology is a specialization of the Fund Regulation Ontology.
The boxes in the diagram depict the prefix of the ontology files (graphs).

- pfrd-* Private Fund Registration Depository – the ontology files related to Form PF.
- fr-* Fund Regulation ontology files

The arrows denote an owl:import. Hedge Fund Reasoning ontology is at the bottom left. It imports the rules ontology hfr-rule-iaa.
