The ontology files

Everything is OWL 2, viewable and editable with any OWL authoring tool — Protégé, for instance.

Core — required

  • CRO2.owl The Cognitive Radio Ontology, version 2. Imports NuVio. 157 classes
  • Nuvio.owl Foundational, domain-independent ontology. Required by CRO2. 13 classes v1.1.1

Extensions — optional

  • Fm3trRadio.owl FM3TR waveform description. 41 classes Incomplete
  • TransmitterAPI.owl Transmitter control interface, extracted from CRO2 in version 2. 8 classes Incomplete

These URLs are identifiers, not just file locations

CRO2 declares its namespace as http://cogradio.org/ont/CRO2.owl# and imports NuVio by absolute URI:

<owl:imports rdf:resource="http://cogradio.org/ont/Nuvio.owl"/>

A reasoner resolving that import fetches it from this address. The files are therefore kept at these exact paths permanently — they are not versioned into subdirectories and are not renamed between releases.
