We should not store RDF. RDF at its basics is just a triple description
format (a predicate about a subject relating to an object). This is like
"node/6 is translation of node/2". We need to somehow adress node/6 and
node/2 and we should be able to mark that the relationship is about
We can of course introduce a new table into core to handle this just for
i18n, and it would be very simple to do:
CREATE TABLE translation (
The problem is that it is too domain specific and not really forward
looking IMHO. We might just end up with this, but we might get further if
we think ahead.
There is an ongoing relationships discussion in the community to somehow
provide this triple-like system to relate nodes to each other (and even
nodes to users etc).
By offloading this work to a relationships API, I hope to get more out of
this "related nodes" concept then just binary relations of translation
nodes. Also this would be something to do for those who are absolutely not
interested in i18n, but would like to help bring some cool stuff into
The existing relations efforts (some ready code) already operate in this
field, and category module uses a similar conceptual approach. I hope that
this way we can also revitalize the book module.
Whether you generate RDF out of these simple triples is up to you
(certainly not with core support).
