Hi Sergio thanks very much for your suggestions.
I'll try the options from importData then:I skipped this part as I have
seen only the access via api and completely miss the last part, sorry. I
have to manage things in a way which can be used by a generic, non
programmer user... so maybe a I can prepare a script for him to use.

Instead about the context section: i have look at the section, but it does
not provide any item in my installation. Is it possible that I have to
explicitly enable it? (maybe some kind of user settings, etc). Does anyone
tried using the H2 web console directly? I think about something like a
"brute" TRUNCATE TABLE triples or similar...

thanks again,
Alfredo
