I have played with an XSL stylesheet called EAD2RDF with good success.

Archivists use EAD as their “MARC” records. EAD has its strengths and weakness, just like any metadata standard, but EAD is a flavor of XML. As such it lends itself to XSLT processing. EAD2RDF is a stylesheet written by Pete Johnston. After running it through an XSLT 2.0 processor, it outputs an RDF/XML file. (I have made a resulting RDF/XML file available for you to peruse.) The result validates against the W3C RDF Validator but won’t have a graph created, probably because there are so many triples in the result.

I think archivists as well as computer technologists working in archives ought to take a closer look at EAD2RDF.

At first glance, a software package called OAI2LOD Server seems to work pretty well, and on a temporary basis, I have made one of my OAI repositories available as Linked Data — http://infomotions.com:2020/

OAI2LOD Server is a software package, written by Bernhard Haslhofer in 2008. Building, configuring, and running the server was all but painless. I think this has a great deal of potential, and I wonder why it has not been more widely exploited.
