The 'QUDT-Quantity Vocabulary" provides a base set of quantities according to the 'Quantity' Schema Ontology. A quantity is a measure of an observable phenomenon, that, when associated with something, becomes a property of that thing; a particular object, event, or physical system. As stated at Wikipedia, in the language of measurement, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum, energy, and weight, and units are used to describe their measure.

Governance concerns how an artifact is provisioned and managed over its lifecycle. Governance also concerns the status tracking and processes that need to exist on information objects and services for a successful initiaitve, mission, program, or project. Such governance needs to outline the relationships between all internal and external groups involved, describe the proper flow of information regarding to all stakeholders, ensure the appropriate review of issues encountered and ensure that required approvals and direction are obtained at each appropriate stage.

Provenance specifies the origin or source of some artifact. The primary purpose of provenance is to capture the time, place, and if appropriate the person responsible, for the creation, production or provisioning of The artifact. Provenance also captures a record of how a version may have been superceded by another version of the artifact.
