This ontology was developed to address the needs expressed by the CONDOR project.

The ontology was designed as an application ontology gathering all entities and relationships involved. It extends the OntoSPM ontology, a general-purpose ontology for Surgical Process Models.

The choice of classes and the relationships that bind them derive from the functional needs expressed in CONDOR, namely mainly, the annotation of surgical videos: description of the actions that take place on surgical videos, leading mainly to naming:

• the actors involved, and possibly specifying the hand involved
• the objects affected by actions, in particular anatomical or pathological objects
• the surgical instruments and materials used
• the description of events such as bleeding or smoke that may affect the legibility of images, or events affecting the field of view
• visibility of objects in images of the videos.

OntoCONDOR focuses on the two procedures considered in CONDOR, namely:

1. ‘Endoscopic cholecystectomy’, and
2. ‘Stomach gastric bypass in obesity surgery’.

Especially, it lists the various 'surgical procedure phases’ and the ‘surgical procedure steps’ involved in these surgical procedures.
