Sagalinked

Sagalinked is a term used to describe a hypothetical data linking paradigm that aims to create persistent, verifiable connections between data entities across multiple information systems. It centers on a standardized linking protocol and data model designed to represent relationships, provenance, and access controls without the need to duplicate data. In sagalinked, records are connected through explicit link objects that reference a source entity, a target entity, and the nature of their relationship, along with contextual metadata such as timestamps and policies.

The core concepts of sagalinked include link records, provenance proofs, and permissioned access. A link record encodes the identifiers of the connected entities, the type of relationship, and cryptographic evidence that the connection is authentic. Provenance information records how a link was created, who authorized it, and under what conditions it remains valid. Access control policies determine who may resolve or evaluate a link, and how linked data may be used or shared. The system emphasizes verifiability, enabling independent verification of connections through signatures or other tamper-evident methods.

Architecturally, sagalinked envisions a linking layer, a registry or index for discovered links, and a cryptographic module responsible for signing and validating proofs. An identity framework and policy engine govern who can create, read, or revoke links. Applications span data integration across organizational boundaries, supply chain provenance, research data curation, and digital rights management, where traceable connections between data assets are valuable.

Challenges for sagalinked include scalability, interoperability with existing data models, and robust privacy controls. When properly implemented, sagalinked can enhance data traceability and interoperability while maintaining control over how linked information is accessed and used.
