Tripoli is a validator for documents conforming to the IIIF presentation API 2.1. It makes it easy to validate documents, apply provider specific heuristics, and even correct documents while they are being validated.
Detailed documentation is available at http://tripoli.readthedocs.io/en/latest/
Python 3.5+ is required to run Tripoli. You can install Tripoli using pip.
> pip install tripoliOnce installed, it's easy to start validating. Tripoli can validate the entire document, and will log informative errors and warnings with helpful paths.
>>> from tripoli import IIIFValidator
>>> iv = IIIFValidator()
>>> iv.validate(some_manifest)
