An ontology proposal is analogous to a Pull Request in a version control system. Proposals serve as a mechanism for reviewing and approving changes made in a separate branch before they are integrated into Main.
For Foundry branches, an Ontology proposal is automatically created when a Foundry branching proposal is created and contains metadata such as reviews, name, and descriptions of the changes being merged into Main. For legacy ontology branches, an ontology proposal is created when the branch is created.
This page explains how to review ontology proposals, including checking resource statuses, reviewing tasks, and viewing the changes made on a branch.
Navigate to the Proposals page through the side tab, where you can choose to view all ontology proposals.
Main Ontology.
Access the Proposal overview, Preview status, Review changes, and Changelog tabs for more information about your individual proposal.
The Proposal overview page centralizes your proposal's stage, changes, tasks requiring review, and selected reviewers. Select Go to proposal overview in the top bar while editing, or navigate to the Proposals tab to view any proposal.

The Preview status tab shows which object types have been indexed, are in progress, or cannot be indexed on your branch. Once an object type is indexed, it will be ready for preview, meaning its data is available on your branch for viewing and testing.

The Review changes tab shows all tasks in the proposal. From here, you can perform the following actions:

The Changelog tab shows a detailed history of changes on a branch. Tasks can be expanded to reveal edits made by a certain user at a certain point in time. You may also directly navigate to the relevant ontological resource.

Viewer access to some resources in the proposal can see the changes related to those resources.
