-Once the metadata records are in the OpenGeoMetadata format, they should be validated to make sure the fields are correctly formatted. The current version of the schema is available as a [JSON-Schema file](https://github.com/geoblacklight/geoblacklight/blob/master/schema/geoblacklight-schema.json). This file format provides support for data validation with the [JSON Schema Vocabulary](http://json-schema.org).
