Provide OA validator

[dazza-codes]

See OA spec at http://www.openannotation.org/spec/core/

e.g., this is an example of using json-schema to validate an API endpoint in tests:

• https://github.com/ncbo/ontologies_api/blob/master/test/controllers/test_projects_controller.rb#L8-L33
• https://github.com/ncbo/ontologies_api/blob/master/test/controllers/test_projects_controller.rb#L83
• https://github.com/ncbo/ontologies_api/blob/master/test/test_case.rb#L155-L168
• https://github.com/ncbo/ontologies_api/blob/master/Gemfile#L9

A very crude starting point:

  # JSON Schema
  # json-schema for description and validation of Open Annotation 1.0, see
  # http://www.openannotation.org/spec/core/
  OA_JSON_SCHEMA = <<-END_JSON_SCHEMA_STR
  {
    "type":"object",
    "title":"Open Annotation",
    "description":"A json-schema for Open Annotation 1.0, see http://www.openannotation.org/",
    "additionalProperties":true,
    "properties":{
      "@id":{ "type":"string", "format":"uri", "required": true },
      "hasTarget":{ "type":"string", "format":"uri", "required": true },
      "hasBody":{ "type":"string", "format":"uri" }
    }
  }
