Patent classification elements are missing in RDF output

[ktk]

There are classifications in the original patent XML data. We need this in the RDF data as Xerox needs that to test their prediction against real (man made) predictions. Currently it seems to be missing in RDF.

The XML elements are: classifications-ipcr (international patent classification) and classification-ecla (european patent classification).

If you need more information about the classification @daniel-treparel knows more and can help out. It seems to be quite a sophisticated classification.

Each patent in the RDF data comes with a classification code (CPC - Cooperative Patent Classification). You can see the code with the query below. Is that code not enough ? What kind of classification information do they need ?

SELECT DISTINCT ?patent ?category_label WHERE {
?patent pmo:classifiedAs ?category . ?category skos:notation ?category_label .
