mettabased

Mettabased is an informal, often domain-specific term used to describe systems, methods, or research that place emphasis on a meta-level foundation for organizing and interpreting information. The term is not widely standardized, and its precise meaning varies by field. In general, mettabased approaches treat metadata and meta-knowledge as central, not ancillary, to the primary data or processes they govern.

Derived from the prefix meta- meaning about itself or beyond, combined with based, mettabased signals that the design's governing principles rely on meta-information. In practice, mettabased design often means separating data from its description and reasoning about data using metadata. Examples include metabases that store schemas, provenance, and access policies; and knowledge bases that store both facts and metadata about those facts. In software engineering, mettabased architectures may enable meta-driven workflows, self-describing APIs, and dynamic reconfiguration.

Benefits of mettabased approaches include improved data discovery, governance, interoperability, and adaptability to changing requirements. Challenges include greater complexity, the burden of metadata management, standardization gaps, and potential performance overhead. The success of such approaches often depends on clear metadata standards, effective tooling, and governance processes.

Related concepts include metadata-driven design, metamodeling, meta-learning, and meta-ontology. Mettabased usage tends to be most prominent in information management, knowledge representation, and adaptive software systems, where understanding and manipulating meta-information enhances flexibility and control.

Because mettabased is not a uniformly defined term, readers should examine field-specific definitions and examples when encountering it.
