KGCL is a standard data model for describing changes to knowledge graphs and ontologies at a high level, and an accompanying human-readable Controlled Natural Language (CNL). A curator can use KGCL to request desired changes, and it can also be used to describe changes that have already happened, corresponding to the concepts of “apply patch” and “diff” commonly used for managing changes in text documents and computer programs.
