Cross-service contracts

The models in biomero_schema.zarr and biomero_schema.imports are wire contracts between BIOMERO-owned services. They provide shared validation while leaving storage, OMERO access, event persistence, locking, and Zarr I/O to the consumer that owns those operations.

The stable serialized form uses camelCase field aliases and is produced with to_dict(). Each contract family carries its own integer schema; this is independent of the workflow descriptor version.

Boundaries

These contracts:

• can identify managed canonical Zarr data and its pixels;
• can snapshot the ordered canonical inputs to a workflow;
• can describe omitted image arrays in a shallow result;
• can request optional importer lifecycle operations.

They do not:

• redefine OME-NGFF or RFC-8;
• prescribe a database or storage-root implementation;
• make an embedded ISCC claim self-verifying;
• require third-party workflows to interpret BIOMERO metadata.
