 ## Usage
 All schemas are available in YAML format under the directory src/oscem_schemas/schema. Files prefixed with oscem_* refer to collections of subschemas, such as those for single particle analysis. Schemas with more specific names, like "instrument," represent individual subschemas that can be modularly incorporated into oscem_* schemas. By using LinkML generator functions, these schemas can be exported to various formats such as JSON Schema, JSON-LD, OWL, CSV and RDF. For metadata validation, we recommend using the JSON Schema versions.
