MNALIB::MnaOpSchema is the type information an MNA operation publishes to the rest of the system. It declares the opType identifier, version, category and binding mode (internal in-process function, cli external executable driven by cliTemplate, or script delegating to an inline MNALIB::MnaScript), plus the MNALIB::MnaOpSchemaPort and MNALIB::MnaOpSchemaAttr lists that describe expected I/O and parameters with their data kinds, default values and required flags.

The MnaOpSchema::validate method is the gatekeeper used by MnaGraph::validate and the GUI editor: it checks that a concrete MNALIB::MnaNode declares every required port, that the attribute types match QMetaType expectations, and that no unknown attribute leaks through. Schemas are normally authored declaratively in mna-registry.json and loaded by MNALIB::MnaRegistryLoader rather than written in C++.
