CiTO
sketchThe Citation Typing Ontology: forty typed relations between documents, and the standard vocabulary of the SPAR ontologies. We borrow it for relations between claims, which is outside its intended scope.

This tab is thin, and saying so is more useful than padding it. The mapping is forty-four lines of notes and a vocabulary file. Nothing has been validated, and no export targets CiTO directly — it is used inside the OXA export as the relation vocabulary.
What it requires
CiTO types the relationship between two documents — cito:supports,
cito:extends, cito:disagreesWith, cito:usesMethodIn
— as an OWL property with a domain and range of bibliographic resources. It is the
standard vocabulary of the SPAR ontologies, and it has no notion of a claim within a paper.
How a claim tree maps onto it
Six of our relations have a CiTO property. The other eight are defined as CiTO subproperties, so a query written against CiTO still finds them.

The gap is instructive: CiTO covers the social relations between papers and misses the logical relations within an argument. Those missing types are what makes a claim graph different from a citation graph.
Does it validate
Unknown. docs/schema-mapping/claim-relations.ttl defines the eight extensions as OWL
subproperties; nothing has been run against a reasoner, and no export is checked for CiTO
conformance. That is a gap, not a result.
What it cannot carry
Anything below the document. CiTO relates works, so every relation in a claim tree is already outside its intended scope — the subproperties are a borrowing of its vocabulary, not a use of its model.
What we would ask its authors
- Is subproperty extension the intended way to use CiTO for relations between units smaller than a document?
- Would intra-document relations be in scope for SPAR, or do they belong in a sibling ontology?
