I have seen the various options. I have not seen what the default one
is when there is no .opt file in the directory (which is my case and
seems to be the initial state). Or did I miss it?

Thanks a lot, after some investigation, here are a few results:
- the problem was that I had no .opt file and that the default
behavior was fixed.opt (or so it seems), when adding a none.opt (or a
stats.opt) the performance went from 1200 to 250ms (with the version
with the big filter version)

You should use
--tdb=PATH_TO_ASSEMBLER_FILE
instead of --loc if you have such a file with more complex settings than
just a location.

If you use TDB as backend, you could run
tdbquery --explain --loc=PATH_TO_YOUR_DB "YOUR QUERY HERE"
and share the output here?
Also, a stats file does exist for your dataset?

Ah excellent, thanks! The two being mutually excluse I had wrongly
guessed they were equivalent.

You may need to use (not sure, not a feature I ever use
myself) though not sure if tdbquery allows for overriding the default graph

Well, this blog post is about creating a custom rule primitive, and this
is also what you'd have to do if you need some custom function that is
not already among the Jena built-ins. So if you really need such a
subtractDates function, why not following the blog and create and
register your own
Dear all,
I'm trying to run tdbquery on my triple store which has a UnionGraph
(assembler attached), but it seems that even the most simple query
doesn't work:
SELECT ?subject ?predicate ?object
WHERE {
?subject ?predicate ?object
}
LIMIT 25
Looking at the results, it seems that tdbquery is

Thanks for your answers! I'm trying to understand why tdbquery doesn't
return any result but in the meantime:

Hi there,
I am trying to load a few datasets created with Protege and saved in the Turtle
format. Whenever I try to load one of these datasets to Fuseki I get the
following error message:
Result: failed with message "SyntaxError: JSON.parse: unexpected character at
line 1 column 1 of the JSON
Fuseki handles Turtle.
The request indicates (usually one of file extension, content-type)
contains JSON(-LD).
What does the log file say the request is?
(if you run with "-v" you get more details of every HTTP request)

Hi Lorenz,
I will follow it then, and try to get it working.
by the way, in the documentation refereed to lessThan, and greaterThan says
the following:
Test if x is <, >, <= or >= y. Only passes if both x and y are numbers or
time instants (can be integer or floating point or *XSDDateTime*).
