The SPARQL editor
Under the builder, the SPARQL editor shows the query the builder wrote. It updates on every change in the builder.
The builder works on its own names for concepts and relations; before the query reaches the editor, Eqlat replaces them with the real IRIs of the ontology. What you read is the query that is sent.
Editing by hand
The editor is a full SPARQL editor: you can change the query, or write one from scratch. Its own play button runs it, as does the builder’s play button. Either way, the results appear below.
A change in the builder replaces the editor’s content, hand edits included.
Queries are sent to the deployment’s SPARQL endpoint in Agrafe, with your token when the deployment needs one. Agrafe answers SELECT and ASK queries; see SPARQL in the Agrafe docs for what the endpoint sees.
An empty editor runs nothing.
