Attachment Point

Go up to Terms and Definitions

Discussion

An attachment point identifies a defined boundary location through which structured information enters or exits an architectural element.

Attachment points support architectural traceability by identifying where information exchange, validation, interpretation, transformation, release, or receipt occurs.

An attachment point differs from an implementation interface. An implementation interface realizes an attachment point through a selected technology. The attachment point defines the architectural boundary and responsibility independently of the implementation mechanism.

Note

An attachment point provides a stable architectural location for analyzing information flow, interface responsibility, and implementation mapping.

Example

A Data Plane service has an attachment point where a structured information artifact enters the service for validation and another attachment point where the validated artifact exits the service for downstream processing.
