markerid

Markerid is a term used in data systems to denote a unique identifier assigned to a marker, point of interest, or tracked feature. The concept appears across contexts such as geographic information systems (GIS), computer vision, augmented reality, and data integration, where markers serve as anchors for data and observations.

In GIS and mapping, a marker represents a geographic location or point of interest, and the markerid links that marker to its attributes, history, and related datasets. In image analysis and AR, markers denote features or targets tracked across frames, with a markerid providing a stable reference so measurements and annotations can be aggregated over time. In inventory tagging, RFID, and barcode systems, markerids identify physical items or tags within tracking and logistics workflows.

Structure and generation: markerids are typically strings or numbers designed to be unique within a namespace. Common forms include UUIDs, ULIDs, or custom IDs that may carry a prefix indicating source or dataset. Some implementations encode additional metadata into the ID or rely on a separate mapping to provide human-readable labels.

Uses: markerids enable fast lookups, cross-referencing across datasets, merging information from different sources, auditing changes, and supporting reproducible analyses and workflows.

Management and considerations: best practices include defining a clear naming authority or ID service, using a consistent generation method, and indexing markerid fields in databases. Privacy and security considerations may apply when IDs reveal system structure or sensitive information, and appropriate access controls should be in place.
