SchemaModi

SchemaModi is a proposed framework for modular schema design intended to improve semantic interoperability of data across web and enterprise systems. It envisions extending the core vocabulary of schema.org with domain-specific modules that can be added, updated, or replaced without disrupting existing data descriptions. As a concept, SchemaModi aims to balance stability with adaptability in rapidly changing information ecosystems.

Architecture and core ideas: A SchemaModi implementation comprises a base vocabulary derived from schema.org, a set of domain modules, a versioning and governance layer, and tooling for validation and mapping. Modules declare dependencies, constraints, and recommended properties, while a central registry tracks versions and compatibility. Data described using SchemaModi can be serialized in JSON-LD, Turtle, or other RDF-aware formats and validated against SHACL or JSON Schema fragments.

Relation to standards and use cases: SchemaModi is designed to be compatible with existing standards, facilitating mappings to DCAT for data catalogs and to FOAF for person metadata. Potential use cases include government portals, e-commerce catalogs, and knowledge graphs, where modular extensions allow organizations to tailor descriptions to domain needs while preserving core interoperability.

Status and reception: SchemaModi remains a concept discussed in interoperability circles rather than a formal standard. Proponents cite reduced schema churn and clearer governance, while critics warn of fragmentation, governance burden, and compatibility challenges. Implementation tends to be experimental or in pilot programs rather than widespread.
