MultiLanguage Support queries in SDO_RDF_MATCH

Question

Hello;
I can insert rows that have language specification for en/es with INSERTs.
I see in the table that I have two rows, one for RDFLANG -es- and another one for -en-.
The question is how can obtain with SDO_RDF_MATCH only the statement for the -es- language if I do not know what is the information of the label.
( ?Person :hasName ?Name @es ) or similar ...

If you want to maintain ordering information , you might also want to use rdf:List. To handle your example, you would use something like:
myshoppingcart hasArticles _:head.
_:head rdf:first article0.
_:head rdf:rest _:item1.
_:item1 rdf:first article1.
_:itemn rdf:rest rdf:nil.
Even though rdf:list and rdf:seq will work for you example, In the general case, you might need to user reification as you suggested if you want to associate generic information with triples.
You can read this for more information:
http://www.w3.org/TR/rdf-mt/#Reif
Oracle supports loading and querying reified triples (they are just like any other triples, with the exception of having to add 4 extra triples per original triple to reify it, so your data set size will increase).
