CRM and FRBRoo are independent of any technical implementation framework.
They are commonly employed using Resource Description Framework (RDF) databases, the lingua franca of linked data but could also be used with other meta-models. Different technologies create a different set of constraints. The design of a knowledge representation system should not be based, or dependent upon, a particular technology. It should represent knowledge in a more generic form. (Oldman, 2014)
They are both designed to easily contribute and integrate large amounts of cultural heritage data into the Semantic Web. Nowadays, considering also the cost of cataloguing services for libraries, it seems much more effective and practical to invest and integrate data in large-scale services rather than in many different local catalogues.
Adopting a common ontology such as FRBRoo will also reduce effort for the complex task of constructing mappings between different metadata schemes or models.
