In support of the migration away from Blazegraph, frontend work is required to integrate the WDQS query UI with the new endpoints.

Incomplete list of likely necessary changes/checks:

• update autocomplete
• update prefixes in prefix menu
• check if the "format query" button still does the right thing
• check if stopping a query still works
• check if reporting of query time and result count works
• check code menu for code snippets for integration with other apps, etc - does it work? does it generate the right code?
• check if downloading of query results works in the various formats
• check if all entries in the "link" submenu of the query result work and are correct
• check if embedded view works (including left and right fly-out menu)
• adapt the visual query editor in the UI (not the Query Builder but the one integrated in the Query UI)

Things to keep in mind while doing this:

• The UI is also used on other Wikibase instances, which will still be running Blazegraph for a while longer.
