Use case: You are using a 3rd party data catalog & lineage going across various DW databases, ETL tools, & BI. You would like to programmatically read the metadata for objects in the OAS catalog. Third party tool able to read the Classic (OBIEE) objects, But looking for endpoints for DV Objects. You are using SOAP API to read the catalog details in the OAS.
Refer: What Are The Available Options To Manage The Catalog In Oracle Analytics Server (OAS)? (Doc ID 2724149.1)
https://docs.oracle.com/middleware/12213/biee/BIEIT/methods.htm#BIEIT286
However, the DV has objects that don't fall into this existing pattern and barely read the objects. DV objects - connections, datasets, data flows, sequences, and workbooks
Idea:
Release catalog REST APIs for Oracle Analytics Server to read the Catalog object's metadata
OAS Rest APIs
