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. The proposals are grouped into the following tabs:
Main ontology.
Access the Proposal overview, Preview status, Review changes, and Changelog tabs for more information about your individual proposal.
To access an individual proposal while on a Foundry branch, choose any ontology resource from the branch taskbar and select View ontology proposal. If you are on Main, navigate to the Proposals tab and select the proposal you wish to view. If you are on an ontology branch, select Open proposal details from the navigation top bar to access the proposal directly.
Within a proposal, you will see the Proposal overview, Preview status, Review changes, and Changelog tabs for more information.
The proposal overview page centralizes your proposal's stage, changes, tasks requiring review, and selected reviewers.

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 given point in time. You may also directly navigate to the relevant ontology resource.

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