Laura,
The reason is that appending all prefixes for each query is going to add a lot
of (unused) overhead for each request.
What software are you using to send the requests to Fuseki?

I use some tdb stores but also hdt for larger graphs (simply because it's more
convenient). I could add a filter before submitting to Fuseki, but in the
general case it looks to me that a Fuseki configuration would be a better
approach. The reason is that appending all prefixes for each query is going to
add a lot of (unused) overhead for each request. With a server-side config
Fuseki could also have an index of default prefixes instead of parsing them for
every query. If Fuseki doesn't have this option, I think it would be a useful
feature.

Subject: Re: Use PREFIXes by default
This seems like something that might be well-handled by a filter or other
processing element outside of Fuseki itself, which could just add a PREFIXes
header to all incoming requests.
Otherwise, are you using TDB? (Because I believe that it does maintain some
information about prefixes used.)

When querying Fuseki, is it possible to have it use all prefixes by default without
having to specify them all the time with "PREFIX ..."? What I have in mind is
something like this:
- have a list of default PREFIXes, somewhere in the Fuseki config files
- send queries without any PREFIX instructions, but tell Fuseki to
automatically use all the PREFIXes it knows
- if the query specifies any PREFIX, these will override any default PREFIX with the same
name defined in the "defaults" list
does this make sense? Is it possible to do this?
