Extension for Temporal Data is ready for testing and implementation

OASIS is pleased to announce that OData Extension for Temporal Data Version 4.0 from the OASIS Open Data Protocol (OData) TC [1] has been approved as an OASIS Committee Specification.

This specification defines how to represent and interact with time-dependent data using the Open Data Protocol (OData). It defines semantics and a representation for temporal data, including operations for querying and modifying temporal data along with vocabulary terms to annotate which data depends on time, and how.

This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
