Introducing Application Telemetry Schema in OpenTelemetry - Vision an…

…d Roadmap (open-telemetry#243) [Easy to read version with images: [https://github.com/lquerel/oteps/blob/app-telemetry-schema-vision-roadmap/text/0243-app-telemetry-schema-vision-roadmap.md](https://github.com/lquerel/oteps/blob/app-telemetry-schema-vision-roadmap/text/0243-app-telemetry-schema-vision-roadmap.md)] Unlike the traditional data ecosystem (OLTP and OLAP), the world of telemetry generally does not rely on the concept of a schema. Instrumentation is deeply embedded in the code of applications and libraries, making it difficult to discover all the possible telemetry signals an application can emit. This gap prevents or limits the development of CI/CD tools for checking, reporting, documenting, and generating artifacts from telemetry signals specific to an application. This document presents a long-term vision aimed at enabling the OpenTelemetry project to address this issue and extend its impact to a broader ecosystem. It proposes extending the initiatives of Telemetry Schema and Semantic Conventions to include concepts of Application Telemetry Schema and Resolved Telemetry Schema. A series of OTEPs and Tools will be proposed in this overarching document to detail each aspect of this vision. Similar (but proprietary) initiative from Facebook: [Positional Paper: Schema-First Application Telemetry](https://research.facebook.com/publications/positional-paper-schema-first-application-telemetry/) **EDIT 1: The OTel Weaver project (a PoC implementation of this OTEP and some of the others mentioned in the roadmap) is now available [here](https://github.com/f5/otel-weaver).** **EDIT 2: The Slack channel [#otel-weaver](https://cloud-native.slack.com/archives/C0697EXNTL3) is dedicated to this OTEP and the associated OTel Weaver project.** --------- Co-authored-by: Yuri Shkuro <[email protected]> Co-authored-by: Reiley Yang <[email protected]> Co-authored-by: Tigran Najaryan <[email protected]>
