QTctid
QTctid is a theoretical identifier concept in distributed computing that encodes temporal and contextual metadata to reference data items across systems. It is designed to support time-aware data provenance, access control, and routing without relying solely on separate lookup structures.
A QTctid typically comprises fields such as origin, creation timestamp, data type or schema tag, version, and
In practice, QTctid is discussed in contexts such as event streaming, data lakes, and microservice architectures
Limitations include the overhead of encoding metadata in identifiers, potential privacy concerns from exposing temporal data,
