OpenSDL Hub integration

The ScienceOL Hub is a public catalog and read-only distribution surface for virtual-laboratory assets. OpenSDL owns the portable package format, OCI mapping, validation, lab CLI, and local content-addressed cache; SciLaxy owns discovery, previews, identity, and hosted catalog policy.

Contract boundary

  • Published asset identity is an immutable OCI reference with a digest.
  • OpenSDL can build and consume packages without SciLaxy or a ScienceOL account.
  • SciLaxy does not reinterpret an OpenSDL source directory; it consumes validated package descriptors and immutable object locations.
  • Public catalog reads do not grant publication authority.

For local development and acceptance details, see the repository's canonical OpenSDL Hub architecture documents.
