dattachers

Dattachers are software components or hardware mechanisms designed to attach data payloads to digital objects. They are used in contexts such as document management, digital publishing, data integration, and IoT, where additional information is bound to an object to improve provenance, interoperability, or accessibility. A datatcher may attach metadata, lineage records, auxiliary datasets, digital signatures, or multimedia assets to the target object.

Dattachers attach payloads by embedding data within an object or by providing external references. They often operate through container formats or metadata schemas, using inline embedding or linked data. Common approaches include embedding MIME parts, using XMP or RDF metadata, or appending separate data streams. They may implement integrity checks such as cryptographic hashes and digital signatures, and may support versioning to record changes over time.

Types and scope: In software, datattachers can be plugins for editors or repository systems that attach metadata to documents. In cloud environments, services may bind datasets to records or objects. In IoT, devices can act as datattachers by appending sensor data to a central event or object. The concept overlaps with data provenance, metadata governance, and digital asset management.

Limitations and standards: Interoperability depends on compatibility among container formats, metadata schemas, and security policies. The lack of universal standards can hinder exchange of attached data. Ongoing work emphasizes provenance, integrity, access control, and discoverability of attached payloads.
