SPARQL UPDATE status

[michaelbrunnbauer]

I have trouble finding information about the status of SPARQL update.

So far I have found out that INSERT/DELETE should work (not from the UI), but I do not know how to submit such a query. I can send non-update queries to the endpoint itself on port 8888 just fine. But adding the access_token parameter and sending an update just gets me

{
    "exception": "SPARQL QUERY was request via the HTTP request, but the following update was sent instead of an query: DELETE WHERE { ?s ?p ?o }",
    "query": "DELETE WHERE { ?s ?p ?o }",
    "resultsize": 0,
    "status": "ERROR",
    "time": {
        "computeResult": 0,
        "total": 0
    }
}

So my questions are:
-How am I supposed to submit updates?
-Are the updates still non-persistent?
-Is it correct that quads/named graphs cannot be inserted yet?
-Is there a document that lists all missing SPARQL 1.1 features?

@michaelbrunnbauer Regarding your questions:

How am I supposed to submit updates? Maybe you had some subtle errors in your command line? Here are some example command lines: https://github.com/ad-freiburg/qlever/wiki/First-tests-with-SPARQL-1.1-Update

Are the updates still non-persistent? As of now, you have to remember your updates and send them again when you restart the server. Persistence is one of the next things that will be added, realistically within the next two months.

Is it correct that quads/named graphs cannot be inserted yet? This is supported. The syntax to enter quads is like this: INSERT DATA { GRAPH <g> { <a> <b> <c> } }

Is there a document that lists all missing SPARQL 1.1 features? There is https://github.com/ad-freiburg/qlever/wiki/Current-deviations-from-the-SPARQL-1.1-standard . If you click on the checks for a commit to the master, you will also find a link to our SPARQL conformance action, which runs https://www.w3.org/2009/sparql/docs/tests automatically for each commit.
