Instance-based semantic graph of a specimen collection process. An instance-based semantic graph documenting a specimen collection process, stored in a named graph instance of the ontology class ‘specimen collection named graph’. The graph relates an instance of ‘specimen collection process’ of OBI with instances of various other ontology classes from OBI, IAO and other ontologies, specifying who conducted the observation, where and when it took place, following which protocol and using which device (e.g., a live trap). The semantic graph furthermore specifies the particular material entity that served as subject and thus as input of the collection process (i.e., the particular material entity), and it specifies the specimen that is the output of the collection process. For reasons of clarity, resources are not represented with their URIs but with labels.
