Validating Schemas

Hello,

I am creating some Schema's (using json-ld, if it matters), following the
schema.org model.

An example of a Schema.org class is (in json-ld format):

    {
      "@id": "http://schema.org/MediaObject",
      "@type": "rdfs:Class",
      "rdfs:comment": "A media object [...]",
      "rdfs:label": "MediaObject",
      "rdfs:subClassOf": {
        "@id": "http://schema.org/CreativeWork"
      }
    }

My question is when creating these schema's, what validation procedures or
tools are being used to validate them before publication? (i.e. making sure
there are no typos, like http://schema.org/CreativeWork vs
http://schema.org/CreativeWrk, etc.)

Regards,
James
