add proper SPARQL editor

[VladimirAlexiev]

https://data.ted.europa.eu/ is a terrible SPARQL editor.
Please add a proper SPARQL editor. As a minimum, it should have:

• display results in a variety of formats, as a minimum as a table
• auto-addition of all prefixes used by the TED KG (eg SKOS)
• if the query has a problem (eg forgotten prefix), show error description and location (don't just disable the Submit button)
• multiple query tabs

Even https://publications.europa.eu/webapi/rdf/sparql is better since it displays results as a table.

However, YasGUI is best.
Here is a saved configuration http://yasgui.org/short/3nVUATliEg that shows a query similar to #13 (but a bit extended).

https://docs.ted.europa.eu/ODS/latest/connecting/sparql.html#_the_results shows results as a table, and lists a variety of formats.
However, the actual endpoint can only display XML:

Perhaps this is part of ongoing work? The site has this notice

Please note: This is a pre-release version of the TED SPARQL Editor. Some features may not be fully functional.

Dear @VladimirAlexiev,

Thank you for your detailed feedback regarding the SPARQL editor on the TED Open Data Service. We appreciate the time you took to outline these specific requirements, as user input is vital to our ongoing development process.

I would like to clarify that the current version of the portal is a pre-release (Beta) application as you pointed out.

We are aware of the current limitations regarding the user interface and query functionality, and we are actively working on a series of enhancements to provide a more robust experience.

Thank you again for your input.

Kind regards,

Victorio BENTIVOGLI
