Aggregation: I want to be able to identify a set of statements as "belonging together", e.g. describing a certain self-contained thing. For example, consider several sets of statements gathered from different RDF/XML pages. How do I "mark" the statements within a single graph? Order: I want to establish an order between the authors of a book: isbn001 dc:creator author1 isbn001 dc:creator author2 How to add ordering without destroying the semantics of dc:creator? You won't tell me that the solution is to use a container like rdf:Bag, right? ;) Sergey
