Using the semantic versioning, produce the data graph as `.ttl` for the release (other formats configurable).

This issue has no description.

The issue names no files, tests, or entry points. Start by locating the release/versioning workflow and the code that builds the data graph; determine how a semantic-versioned release should produce .ttl and where alternate formats can be configured. Done means the release output includes the expected .ttl graph and configurable format handling is covered by the repository's relevant checks.
