Hi, The more I think about how the non-i18n Drupal world would benefit from i18n features comming into core (so how do we convince you with all the good stuff :) is that relations are perfect implementation candidates for node translation connection storage. Previous discussion and implementation: Create generalized relationship module http://drupal.org/node/28480 Relationship - Node linking and Metadata http://drupal.org/project/relationship Relationships & site structuring group http://groups.drupal.org/relationships-site-structuring The RDF triple approach is a true and tried method to handling relations (see the existing module description). I would propose that we should include a small triple handler in core. This would be good for i18n and other modules to use, so we might get to a win-win situation. Contrib modules can extend on this triple handling with RDF generation and such. Who is willing to work on relations for core? IMHO we should look into reimplementing the book module functionality first with this, since the book module interface is quirky as it is anyway. There the storage of weight might be a good question. While triple's don't allow you to store weights, the RDF representation allows for 'primary data' to be connected to the triple (rdf:value for those RDF-literate). This approach can be used to represent the weight IMHO. Gabor
