Perform a Yelp search for local businesses using the Yelp API https://www.yelp.com/developers/documentation/v3/business_search
The full Yelp API allows many parameters for searching for business. This accessor demonstrates a simple query for a particular type of business near specific geographic coordinates.
This accessor extends the YelpSearch accessor to produce a schema.org compatible Turtle ontology. Since schema.org is a linked data ontology, additional information about the ontology can be found by checking out the URIs in the output.
