They’ve added characterization to citations present on websites using CiTO. You can encode citation frequencies using CiTO, too. Another purpose is to characterize the cited works themselves. In doing so, he has adopted the FRBR entity model. For an example, they made FRBR entities for Gone with the Wind. The move, while based on the novel is a new creative work. The novel can have a variety of expressions. For these and more reasons it makes it a good example.
SWAP also uses the FRBR classification, and CiTO has adopted terminology and definitions from SWAP. However, SWAP is concerned with the metadata describing a single work. CiTO describes aspects of scholarly works out of scope for SWAP (e.g. relations between citing and cited works). Another similar ontology is BIBO, but that deals with legal works, and BIBO lacks terms essential to CiTO. BIBO is essentially orthogonal with CiTO. Further, BIBO doesn’t use the FRBR classification. SWAN is another ontology designed to characterize rhetorical statements with text. It is limited in scope and still under development (just a cygnet!) but clearly relevant to CiTO. They’re starting a collaboration with Tim Clark.
What is the proper home for this? It’s not a biological ontology, so maybe doesn’t belong in OBO? They also want a nice authoring tool.
