Pizza BFO Ontology: Description back to ToC

A pizza ontology aligned to BFO 2020 - the BFO that NFDIcore 3.0.5 builds on - and made from BFO and NFDIcore design patterns. It holds no individuals: its instance data is a separate knowledge graph built from ROBOT templates.

IRI: http://purl.obolibrary.org/obo/BFO_0000023

A realizable entity the manifestation of which brings about some result or end that is not essential to a continuant in virtue of the kind of thing that it is but that can be served or participated in by that kind of continuant in some kinds of natural, social or institutional contexts.
(Elucidation) A role b is a realizable entity such that b exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be & b is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed
Example 
John’s role of husband to Mary is dependent on Mary’s role of wife to John, and both are dependent on the object aggregate comprising John and Mary as member parts joined together through the relational quality of being married.

concretizesop back to ToC or Object Property ToC

IRI: http://purl.obolibrary.org/obo/RO_0000059

A relationship between a specifically dependent continuant or process and a generically dependent continuant, in which the generically dependent continuant depends on some independent continuant in virtue of the fact that the specifically dependent continuant or process also depends on that same independent continuant. Multiple specifically dependent continuants or processes can concretize the same generically dependent continuant.
Example 
A journal article is an information artifact that inheres in some number of printed journals. For each copy of the printed journal there is some quality that carries the journal article, such as a pattern of ink. The quality (a specifically dependent continuant) concretizes the journal article (a generically dependent continuant), and both depend on that copy of the printed journal (an independent continuant).
An investigator reads a protocol and forms a plan to carry out an assay. The plan is a realizable entity (a specifically dependent continuant) that concretizes the protocol (a generically dependent continuant), and both depend on the investigator (an independent continuant). The plan is then realized by the assay (a process).
