MacKenzie It was not my intention to create a "vendor tone" around DSpace; for what its worth I have had (and seen others having) similar kinds of discussions around other OSS on other mailing lists ... with no "adverse reactions". My intention was not to try and highlight any shortcomings or cast any aspersions on the usability of DSpace; rather, I was trying to see where it could or might not meet our specific needs. We do have a preference to use an OSS solution - and one of the great aspects of the OSS development model is that there is often are choices; with each one having its own pros or cons. I have already learnt a lot on this thread to help me with that choice. I also wish you well in your endeavours to continue with DSpace development - as you say, there have been inputs from the members of the DSpace technical community ... but don't forget to hear the occasional voices of the less technical as well!

>>> MacKenzie Smith <[EMAIL PROTECTED]> 2007/06/04 03:30 PM >>> Dear Derek, Richard, et al. I am occasionally amazed at the degree to which DSpace, after 5 years as an open source software project, is still talked about as if it were a vendor product... of course it has limitations... all software does, especially when it's five years old and actually getting used. But in this the outcome is in *your* hands. Based on its cumulative experience, last year some members of the DSpace technical community produced an architecture for needed improvements to the system: http://wiki.dspace.org/index.php/ArchReviewReport Michele Kimpton, the new Executive Director of the DSpace Foundation, is now at work on how we can collectively move that forward. We need to figure out the funding model to get this work done, but I'm pretty confident it will happen... there are too many organizations depending on DSpace now to let it age out of existence, mine included. And there's always that data export exit strategy if it does -- one of the original requirements of the system that acknowledges how short the life span of software is these days, and how little we still know about the "right" way to build these systems.
