Communicationfrom

Communicationfrom is a term used in information systems to denote the origin of a communication object, such as a message, event, or data packet. It is typically used as a metadata attribute that identifies the source from which the content originated.

In practice, communicationfrom appears in messaging schemas, event streams, and logging. It supports routing decisions, auditing, and data provenance by enabling systems to trace back to the originating component, service, or user. It can also aid access control and trust formation by providing a source identifier.

The semantics and format of communicationfrom vary by implementation. It is commonly a string value that may be hierarchical (for example, a domain or service path) and sometimes includes version or lineage information. Some schemas treat communicationfrom as a structured object with fields such as id, type, and timestamp.

Relation to other concepts: communicationfrom overlaps with provenance, origin, sender, and source. It is primarily a metadata field rather than content, and its adoption is not standardized, with different organizations choosing different naming conventions and schemas.

Examples: In a JSON payload: {"communicationfrom":"sensorA"}. In a log entry: communicationfrom=sensorA, timestamp=... Privacy and governance considerations apply: minimize disclosure when possible, and log only what is necessary for auditing.
