Open Digital Architecture Toolkit

ODA comprises an architecture framework, common language, and design principles.  It defines standardized, interoperable software components organized into loosely coupled domains.  These components expose business services through Open APIs built on a common data model.  ODA provides machine-readable assets and software code, including a reference implementation and test environment.

Members of the TM Forum Open Digital Architecture (ODA) Project from around the globe are collaborating to produce valuable resources that are actively developing the ODA standards.

Below you will see all the resources published by the project so far. We have divided the resources into toolkit sub-categories according to the ODA domain they belong to. 

Note, these resources, like other TM Forum Toolkits, are accessible only by the members of the Forum. If your company is not a member, please fill the Membership Interest Form and we will get in touch with you.
