Feature: SPARQL insert

[BenjaminHofstetter]

SPAQRL Insert is not officially supported.

I can categorize this feature into four areas:

Endpoint: Some systems use different endpoints for UPDATES and normal Queries.

Recognize UPDATE queries: To use another endpoint for updates, we need to recognize the query kind and distinguish between queries and updates to choose the correct endpoint. Query recondition is already implemented.

Authentication: Some endpoints need different authentication for updates. Currently, this is limited to Basic Auth. If we have two endpoints, we need to handle this.

Files: What should updates on Files do? We can load many files into Oxygraph at once, but where should write go? This is currently unknown.

• recognize updates
• handle update queries
• allow to configure update/query endpoint pairs Feature: Pair UPDATE and QUERY endpoint connections #112 SPARQL insert doesn't work with Stardog #21 Allow INSERT instruction #87
• qlever Feature: Support updates on QLever #113
