Please upgrade from version 0.9.0 to version 1.0.0!

    Recursive: Validate all assets in a collection or catalog

Valid COLLECTION: True

Schemas validated: 
    https://cdn.staclint.com/v0.9.0/collection.json

STAC Best Practices: 
    Object should be called 'collection.json' not 'landsat-collection.json'

    A STAC collection should contain a summaries field
    It is recommended to store information like eo:bands in summaries

    Links in catalogs and collections should always have a 'title' field


Recursive validation has failed!

STAC Best Practices: 
    Item name 'LC81530252014153LGN00' should only contain Searchable identifiers
    Identifiers should consist of only lowercase characters, numbers, '_', and '-'
    https://github.com/radiantearth/stac-spec/blob/master/best-practices.md#searchable-identifiers

    Item file names should match their ids: 'landsat8-sample' not equal to 'LC81530252014153LGN00

    A link to 'self' in links is strongly recommended
