Hi David, Those are the ids of statements. They are formed using the statement's UUID, which typically uses the item id (sometimes with a lower-case "q") as its first part. However, the exact form of the IDs should not be used to find out what the thing is or which item it belongs to: all of this information is encoded in triples in the dump, and these should be used to find out if a URI refers to an item or a statement etc. Cheers, Markus On 08.01.2016 12:45, David Przybilla wrote:
