Feature Request: Support loading Cube schema files in Apache Ossie format instead of current YAML format

[mfournioux]

Summary

Cube currently uses its own YAML schema format.

Apache Ossie is an Apache-licensed open standard that defines a similar semantic model format — datasets with fields (dimensions + measures), relationships, primary keys, and more.

Question

Does Cube plan to support loading schema definitions written in the Ossie format directly, instead of (or alongside) the current Cube-specific YAML format?

In practice, this would mean:

• Writing schema files in Ossie format instead of Cube's native .yml format
• Cube could parse Ossie YAML and use it to build the Cube model without any conversion step
• The same semantic model could be loaded by Cube without rewriting it in Cube-specific syntax

Why this matters

• Single source of truth: Define the semantic model once, use it with Cube and other compatible tools
• Vendor neutrality: Ossie is open and Apache-licensed, not tied to any single vendor
• Reduced duplication: No need to maintain parallel schema definitions
