# Inventory This part provides a specification for the inventory. It is used for design phase and as validation helper. > Cue is less verbose and easier to understand and maintain than json-schema. > Json-schema, if needed can be easily generated on-the fly. ## Checking validity Directly check a json against the schema `cue vet inventory.json root.cue -d '#Root'` ## Json schema Export the json-schema i.e. for usage in python / javascript / nix `cue export --out openapi root.cue` ## Usage Comments are rendered as descriptions in the json schema. ```cue // A name of the clan (primarily shown by the UI) name: string ``` Cue open sets. In the following `foo = {...}` means that the key `foo` can contain any arbitrary json object. ```cue foo: { ... } ``` Cue dynamic keys. ```cue [string]: { attr: string } ``` This is the schema of ```json { "a": { "attr": "foo" }, "b": { "attr": "bar" } // ... Indefinitely more dynamic keys of type "string" } ```
