Ontology

Data Lifecycle Ontology

The purpose of the Data Lifecycle Ontology is to provide a set of conceptual entities, agents, activities, and roles to represent the general data engineering process. Furthermore, it is the basis for deriving specific domain ontologies which represent lifecycles of concrete data engineering projects such as DBpedia or Seshat. DLO uses the W3C PROV ontology represented by the classes Role, Person, Entity, and Activity. It uses the Process class which is derived from Activity to implement the Linked Data Stack lifecycle stages as subclasses.
