I have successfully been able to being the systematic transformation process of EAD and MARC to RDF/XML, and consequently been able to literally illustrate the resulting triples. [1, 2] From the blog posting [3]: The resulting images are huge, and the astute/diligent reader will see a preponderance of literals in the results. This is not a good thing, but it all that is available right now. On the other hand the same astute/diligent reader will see the root of the RDF/XML pointing to a meaningful URI. This URI will be resolvable in the near future via content negotiation. This is a simple first step. The next steps will be to apply this process to an entire collection of EAD files and MARC records. After that the two other things can happen: 1) the original metadata files can begin to include URIs, and 2) the XSL used to process the metadata can employ a more standardized ontology. It is not an easy process, but it is a beginning. Right now, something is better than nothing.
