This directory contains templates used by the Publish to BCR GitHub Action to automatically publish new versions of cel-spec to the Bazel Central Registry (BCR).

• metadata.template.json: Contains repository metadata including homepage, maintainers, and repository location
• source.template.json: Template for generating the source.json file that tells BCR where to download release archives
• presubmit.yml: Defines build and test tasks that BCR will run to verify each published version

When a new tag matching the pattern v*.*.* is created:

1. The GitHub Actions workflow .github/workflows/publish_to_bcr.yml is triggered
2. The workflow uses these templates to generate a BCR entry
3. A pull request is automatically created against the Bazel Central Registry
4. Once merged, the new version becomes available to Bazel users via bzlmod

The following variables are automatically substituted:

• {OWNER}: Repository owner (google)
• {REPO}: Repository name (cel-spec)
• {VERSION}: Version number extracted from the tag (e.g., 0.26.0 from v0.26.0)
• {TAG}: Full tag name (e.g., v0.26.0)
