Alignmentid

Alignmentid is a term used in information systems to denote a unique identifier associated with an alignment operation, mapping, or state that links two or more entities. It is not a standardized concept across industries; its exact meaning depends on the application, but in most contexts it serves as a stable reference that allows systems to record, trace, and reuse the results of an alignment step.

In data processing and integration, an alignmentid may be generated when source and target schemas, records, or datasets are aligned. The identifier can be a UUID, GUID, or hash value and is typically immutable to preserve auditability. It enables joins across pipelines, supports data lineage, and facilitates reprocessing or rollback of an alignment without duplicating data.

In geospatial and computer vision workflows, alignmentid may refer to the identifier for a particular geometric alignment or transformation that aligns coordinate frames or images; it ties together configuration parameters and results so that the same transformation can be reapplied consistently.

In software APIs and databases, alignmentid is often exposed as a field name or parameter (for example alignment_id) that carries the reference to an alignment operation rather than the data itself. Its lifecycle is project-specific; some teams discard it after use, others retain it in audit logs.
