Mark Jordan (digitizationblog) is starting to write a simple, general purpose digital library content management system (DLCMS) based on Drupal. In his July 19 blog posting, Jordan asks for feedback on a page-turner prototype that he has built. According to his post, Jordan hopes to demonstrate a version of this DLCMS at the Access 2006 Conference in October.
If this is a topic that interests you, please encourage Mark Jordan. I'm sure he'd like to know that he is not toiling away in the "wilderness." Hopefully he'll post updates about his efforts to his blog, as well as his Access 2006 demostration.
