Local filesystem based JSON catalogue, usable e.g. with package `jsonschema`
Project description
Package jsoncatalogue allows reading set of JSON files from directory structure resembling urls.
Files are loaded and provided as simple url: jsoncontent dictionary.
Such a dictionary can be used as catalogue of JSON schemas for JSON Schema validation.
Installation
$ pip install jsoncatalogue
Structure of directory with JSON files
If you want to have catalogue for Swagger v1.2 validation:
./catalogue/http/wordnik.github.io/schemas/v1.2/apiDeclaration.json ./catalogue/http/wordnik.github.io/schemas/v1.2/infoObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/authorizationObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/modelsObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/operationObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/parameterObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/dataTypeBase.json ./catalogue/http/wordnik.github.io/schemas/v1.2/oauth2GrantType.json ./catalogue/http/wordnik.github.io/schemas/v1.2/resourceObject.json ./catalogue/http/wordnik.github.io/schemas/v1.2/dataType.json ./catalogue/http/wordnik.github.io/schemas/v1.2/resourceListing.json
where
catalogue - is catalogue “home” directory (can be deeper)
http- is protocol name. Can be any other, like ftp…
wordnik.github.io - domain name
schemas/v1.2 - local path to JSON files
apiDeclaration.json - actual JSON file - must be valid JSON file (no other requirement exist)
As you see, there are no complex rules to follow, just have uri leading to valid JSON file (which is not even required to have an extension “.json”)
Loading JSON Catalogue from directory
>>> from jsoncatalogue import Catalogue
>>> catalogue = Catalogue()
>>> catalogue.add_directory("catalog")
>>> catalogue.add_directory("../other/catalog")
>>> catalogue.store
{"http://exam.ple/schema/one.json": {...},
"http://exam.ple/schema/two.json": {...},
"http://wordnik.github.io/schema/v1.2/apiAuthentication.json": {...}
"http://no.extensi.on/schema/pets": {...}
}
And this is all. You now have a dictionary with uris and related JSON content. The JSON content is already loaded and is represented as dictionary.
Using catalogue for JSON Schema validator
This catalogue.store can be assigned e.g. to jsonschema validator:
>>> from jsonschema import Draft4Validator >>> validator = Draft4Validator() >>> validator.resolver.store = catalogue.store
From now on, validator will know about schemas from catalogue
