Hi Curt, Does the schema now impose an order on prov "attributes"? Without order, I have failed to define an object mapping (with jaxb) that is useful from an OO perspective. Likewise, i have not managed to define a meaningful ORM mapping. Now, this is my experience with these tools, maybe somebody has succeeded. In summary, The problem I encountered is as follows. If there is a choice (instead of sequence) between say, prov:type, prov:location, prov:label, all these elements are mapped to a single java method or a single sql column. This results in non natural code or SQL queries. Because of this, my preference is to keep these in a sequence. It does not at all reduce expressivity, I think.
