Using version 2.2.4 of StarDog I can not load the following turtle file:

%% cat noload.ttl
<urn:a> <urn:b> false, true .

as I get the following error.

% stardog data add single noload.ttl
Adding data from file: noload.ttl
Expected '.', found 't' [line 1]

If I add a space between false and the comma then it loads:

% stardog data add single loads.ttl
Adding data from file: loads.ttl
Added 2 triples in 00:00:00.190

I'm guessing it just happens for booleans, since the following works:

% cat ints.ttl
<urn:xx> <urn:yy> 12, 24 .
% stardog data add single ints.ttl
Adding data from file: ints.ttl
Added 2 triples in 00:00:00.223

Thanks,
Doug

Yes, this seems to be a bug in RIO [1] which is what we're using for parsing RDF.

Cheers,

Mike,

just curious -- are you using both Sesame and Jena in Stardog? Why not
stick to a single API?

The SNARL API would be considered a single API, but since the vast majority of existing projects are already using either Sesame or Jena, we provide as a convenience implementations of both the Sesame and Jena APIs which are simply wrappers around SNARL. This way legacy projects don't have to rewrite code to use Stardog, they can simply keep using Repository or Model respectively.
