This is the codebase for the IIIF Presentation Validator, which can be seen at http://iiif.io/api/presentation/validator/.

uv sync 

pip install . 

Either option will install the iiif-validator command. This command allows you to run the validator server or validate local or remote files from the command line.

To validate a manifest from the command line:

# Using uv uv run iiif-validator validate --version <version> <url-or-file> # Using pip install iiif-validator validate --version <version> <url-or-file> 

It is also possible to validate a directory and any sub directories:

# Using uv uv run iiif-validator validate-dir --version <version> --extension <extension> <directory> # Using pip install iiif-validator validate-dir --version <version> --extension <extension> <directory> 

To run the server:

# Using uv uv run iiif-validator serve # Using pip install iiif-validator serve 

This should start up a local server, running at localhost:8080. To test it, try this url and see if you get a JSON response that looks like this:

{ "url": "http://iiif.io/api/presentation/2.1/example/fixtures/1/manifest.json", "error": "None", "okay": 1, "warnings": ["WARNING: Resource type 'sc:Manifest' should have 'description' set\n", "WARNING: Resource type 'sc:Sequence' should have '@id' set\n", "WARNING: Resource type 'oa:Annotation' should have '@id' set\n", "WARNING: Resource type 'dctypes:Image' should have 'format' set\n"] }

You may also use --hostname to specify a hostname or IP address to which to bind and --port for a port to which to bind.

It is also possible to run the validator against JSON documents which are in a Github repository using a github action. An example is below:

 - name: Run IIIF validator uses: IIIF/presentation-validator@main with: directory: path/to/json version: 3 extension: .json 

• directory is required. The validator will start at this directory and then go through any sub-directories looking for json files to validate.
• version is optional. If supplied any json files will be validated against this version. If its not supplied the validator will look inside the json to see which version is specified in the @context
• extension is optional and defaults to .json. - name: Run IIIF validator
