...
In the event that there are no handlers registered for a specific type, the module will store the payload as an unstructured "blob" in the OpenMRS database. Any document-type data such as PDFs or image data can be stored this way. Blobs will be saved as observations linked to a new encounter for the specified patient. The Unstructured Storage module provides appropriate obs handlers for this functionality, and therefore the Content Handler module will not handle the implementation. It will simply treat an unstructured payload as a complex observation, but will however provide a code handler instance for use by the getContentHandler method.
