hi,

if you do not want to use existing  libraries/systems (don't know your
motivation since they are very good) but want to get fast results, then i
would think about using Prolog:

* you can encode each RDF statement as a ground fact
e.g.:
triple("ora lassila", "foobar:author", "http://w3.org/Ora").

* if you want to query information from the >5 files (which would be
encoded in a large list of the "triple" ground facts) you can simply use
the prolog query machinery

e.g.
?- triple(X, "foo:name", NAME), triple(X, "bar:age", AGE), AGE>19.

* there are many good and free prolog engines out there (e.g. swi prolog,
xsb) and there are easy ways to connect prolog to web servers.

cheers,
j.

Hello, i want to develop an rdf application without using Jena.

I want to read more than 5 rdf files (v-card rdf files) and show in a
browser
some pattern or some information about a specific search pattern. Example:
People that has more than 20 years old and be developers.

Question:

1) Must i use Joseki to do this?.

2) Can I integrate xml, xsl and rdf?.

3) Are something similar to xsl in rdf?.

Please, send me any suggestion about how can i do that please.


thanks a lot,
Federico from Argentina.
