> This is a sub-module used as a dependency by both the [Lectern Client](https://www.npmjs.com/package/@overture-stack/lectern-client) and [Lectern Server](https://github.com/overture-stack/lectern/blob/develop/apps/server/README.md).

> If you are building an application that will interact with a Lectern Server over HTTP, or wants to validate data using a Lectern Dictionary, you likely want to import the [Lectern Client](https://www.npmjs.com/package/@overture-stack/lectern-client).

This package defines the structure of Lectern Dictionaries, including providing the TypeScript type definitions to use the dictionary in code and the schemas to validate that a given JSON object is a valid Lectern Dictionary.

The Lectern Dictionary meta-schema is formally defined in TypeScript and exported as the type `Dictionary`. This definition is created using `Zod` schemas, which are also exported from this package and available for use to confirm a given object is a valid Lectern Dictionary.

A [JSON Schema definition](https://github.com/overture-stack/lectern/blob/develop/generated/DictionaryMetaSchema.json) of the Lectern Dictionary structure is also available if you are looking for a non-TypeScript mechanism for validating Lectern Dictionaries.
