Dear everyone,
I've updated the installation bundle for SemanticXO and also fixed a few
bugs reported on this mail thread.
To play around with the code:
* go to http://git.sugarlabs.org/semanticxo/main/trees/master/patch_my_xo
* put the files "patch_my_xo.py" and "semanticxo.tgz" somewhere on the

Great! Many thanks :)

I use Redstore 0.5.4. It requires the latest versions of Redland libraries
which are

Yes, all the development & testing is done with Sugar 0.94.
However, I still found that redstore had extra requirements that were not
packaged.

As you rightly guessed, there are some parts of the API that still have to
be implemented.
The things I've tested so far work fine though: launch the emulator, create
some entries by using the activities and browse the content of the journal.

Looking for text matching a given regular expression is part of the SPARQL
recommendation, the query language for triple store. So all the triple
stores should implement at least that. There are also some, like OWLIM and

However I agree this is an important question, I can not give any proper
answer to it yet.
Some time ago I did some performance test for the triple store:

How compare SemanticXO journal to our actual implementation, regarding to
disk space and performance (in a xo)

After having created some Journal entries, go to this address and display
the content of "named graphs" to see how the records are turned into
triples. The port is public so you can also browse the content of

Normally, that would be more something like:
document,hasAuthor,author
document,hasTitle,"blah"
...
This describes "document" and connect it to "author", which would in turn
be described by:
author,firstName,"blah"
author,lastName,"blah"

Dear all,
A part of the project "SemanticXO" concerns the implementation of an
alternative Journal implementation making use of the triple store backend.
Triple store are data bases optimised to store factual information in the
form of statements linking a subject, a property and a value. This mak
