Besides the great pointers on the IntegratingSolr page, libraries integrating Solr have their own unique challenges that the rest of the computer programming world is advised to steer clear of. Brain storming some ideas of what can go here:
(MARCXML/MODS/MADS/EAD/TEI) -> Solr XML XSLT examples
Terry Reese has kicked this area off to a great start, video and all, showing
MARC -> Solr via MarcEdit

MARC4J
Emily Lynema posted the following to the
code4lib preconference list:
For any solr4lib folks who are Java friendly and looking for a good (aka, fast and easy) way to go from MARC to MARCXML. I just discovered that the MARC4J package has a class that can be run as a command line utility (MarcXmlDriver) to convert a MARC file to a MARCXML file. I think it took me maybe 10 minutes to process 2K of records. It also does MARC8 to UTF-8 conversion. Oh, and I'm pretty sure the MarcXmlDriver will also post-process the MARCXML output via user-defined xslt. Although I haven't tested that part myself yet. http://marc4j.tigris.org/
