This specification defines a standard for representing and propagating a set of application-defined properties associated with a distributed request or workflow execution.| www.w3.org
Status: Alpha Overview Environment variables provide a mechanism to propagate context and baggage information across process boundaries when network protocols are not applicable. This specification extends the API Propagators to define how the TextMapPropagator can be used with environment variables. Common systems where context propagation via environment variables is useful include: Batch processing systems CI/CD environments Command-line tools Propagator Mechanisms Propagating context via ...| OpenTelemetry
Status: Stable Overview Cross-cutting concerns send their state to the next process using Propagators, which are defined as objects used to read and write context data to and from messages exchanged by the applications. Each concern creates a set of Propagators for every supported Propagator type. Propagators leverage the Context to inject and extract data for each cross-cutting concern, such as traces and Baggage. Propagation is usually implemented via a cooperation of library-specific reque...| OpenTelemetry
Status: Stable. Overview A Context is a propagation mechanism which carries execution-scoped values across API boundaries and between logically associated execution units. Cross-cutting concerns access their data in-process using the same shared Context object. A Context MUST be immutable, and its write operations MUST result in the creation of a new Context containing the original values and the specified values updated. Languages are expected to use the single, widely used Context implement...| OpenTelemetry
Specification documents (files) may explicitly define a “Status”, typically shown immediately after the document title. When present, the “Status” applies to the individual document only and not to the entire specification or any other documents. The following table describes what the statuses mean. Maturity levels The support guarantees and allowed changes are governed by the maturity level of the document. Maturity levels are defined in OTEP 0232 and follow the OpenTelemetry project...| OpenTelemetry
The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document provides an overview of HTTP architecture and its associated terminology, defines the "http" and "https" Uniform Resource Identifier (URI) schemes, defines the HTTP/1.1 message syntax and parsing requirements, and describes related security concerns for implementations.| IETF Datatracker
