httk.store.served_specs¶

Derive OPTIMADE property names and types from the storage schema IR.

This module deliberately depends only on the neutral schema representation and httk-core definitions. SQL and Mongo layers can therefore share the same property derivation without importing one another’s backend.

Functions¶

`served_specs`(schema, prefix)	Return the served `(name, field spec, fulltype)` triples.
`definition_fulltype`(definition)	Return the OPTIMADE fulltype declared by a property definition.

Module Contents¶

Returns:

One triple for every schema field with an OPTIMADE value type.
