Re: [stardog-users] SPARQL DELETE ERROR with stardog 1.1

[Kendall Clark]

Stardog 1.1.1 doesn't support SPARQL 1.1 Update *query language*. It
supports Update in the data protocol.

We will lift this restriction in a future release, as soon as we can
implement it securely (i.e., not liable to injection attacks).

Cheers,
Kendall

So are SPARQL 1.1 updates actually in Stardog now, just disabled? Couldn't you allow an admin to enable it if they choose? :)

I was curious about that when you first mentioned it...  Maybe I'm just not thinking of this the right way, but shouldn't preventing injection be a problem for the calling application to worry about?  Like if the account I connect to Stardog with has write permissions, I should be able to do whatever I want, and if my code is stupid enough to allow an injection attack from my users than that's my fault. What if your secure implementation considers something as an injection attack but it's something I am doing intentionally?

I know that you've though all this through, I am just curious about it.

In a branch, but not in the released product.

Yes and no. It should be possible for the calling application to
prevent injection attacks in some way, ideally in a way based on
Stardog, so that we know it's done properly.

This is a reasonable position; it's not the one we've taken to date.

It will be disable-able in that case. Which, yes, is exactly like the
case now, but in re: security, we wanted to be very conservative and
very careful.

We don't have a release in mind yet but full Update support will be
available sooner than later.

Any update on this, is it available in the latest release 1.1.3?

No.  SPARQL update probably won't be available until 1.2.

so there is no other ways to edit tuple data once entered?

[Kendall Clark]

Use the HTTP protocol, Java APIs (there are 3), or CLI.

Other than those 5 ways, there are no other ways presently.

Got one example code for inserting and deleting graph

Try this one.

There are clearly examples of adding and deleting data in precisely the chapter that you refer to.

Further, since Stardog supports Sesame and Jena, all the documentation about how to do adds and deletes in Sesame or Jena exist.

Facts are wonderful things!

Cheers,

Kendall
