Hi PriyeshThere is no direct mapping between Open APIs and the eTOM business process framework.In the context of the ODA functional architecture, each ODA component definition includes an uber-mapping between multiple Frameworx elements relevant to that component - the Information Framework (SID), eTOM, Framework functions (taken from TAM), and the Open APIs.You can see this in the published definitions for Product Catalog and Service Order components.Hope it helps
The CurateFx tool does support the mapping between Business Processes and APIs, and mappings between ODA-CA and APIs have been available in CurateFx for some time. We have also seen several Catalyst teams create mappings between items such as Business Capabilities, ODA and eTOM – these example projects are also available in CurateFx. You may be interested to review some of the mapping examples the that have been created in an example CurateFx TM Forum Toolkit project. This CurateFx project contains a variety of examples and How to videos many of which relate to the mapping of elements between different TM Forum elements.
