What is the easiest way to develop a new information extractor?
The Simple Python Extractor is the simplest way to create a new extractor. It works for cases where you want to extract structured metadata or a preview from a single file. For more complex examples you can try creating an extractor using the more involved pyClowder extractor. For advanced users, extractors can be written in any language, the only requirements are a RabbitMQ driver and the ability to call HTTP endpoints and parse JSON.
