** Apologies for receipt of duplicate postings **


I have noted your message on more than one list, so I've taken the liberty of copying each of them to inform individuals who follow those lists.  Regarding a comparison of repository software, our group at Johns Hopkins is conducting a technology-based analysis of repositories and applications with funding from the Mellon Foundation.  Our choices include DSpace, Fedora, ePrints, Digital Commons (ProQuest's offering based on BePress), and applications include Sakai, and various e-publishing systems such as Open Journal Systems (OJS), and DiVA.  We are working with the DPubS team to include their software as well, and we're also considering if we can include Moodle and LionShare as well.  Finally, we have a strong emphasis on digital preservation capabilities for the repositories.  The main purpose of our analysis is to examine each of these systems with a transparent, clearly defined methodology beginning with stories or scenarios that are mapped into use cases and what we are calling key events, from which we are defining functional requirements for repositories to support various types of content and uses.  In addition to the repositories and applications, we are examining whether JSR-170, OKI DR OSIDs and perhaps an implementation of IMS DRI can support integration of repositories and applications through a generalized interface layer that spans across different services without specific out of band agreements.

While we haven't included costs information, we have tracked installation issues, features, and other technology matters.  Ultimately, we hope to develop a methodology that might allow the community to address the types of question you describe with an objective, rigorous approach, and a taxonomy of repositories that will allow us to identify gaps in functionality.

Our project wiki is available at https://wiki.library.jhu.edu/display/RepoAnalysis/ProjectRepository

From this web page, you can find our original proposal to the Mellon Foundation and two presentations at previous CNI and DLF conferences under the "Documents" tab.

I would be happy to answer any questions you (or others) might have in this regard.

Subject: Comparison of EPrints, DSpace and Fedora

I am doing a comparison of functionality and adopter experiences for the two
most widely used institutional archive-creating software packages for
repositories: EPrints and DSpace, and also Fedora (a minor player globally
but possibly important in Australia).  I am seeking your help in collecting
information. Information about other packages would also be welcome.

(1) If you have used or compared any of this software, could you
please take the time to let me know what you consider the respective
advantages/disadvantages of each to be, and for what purposes? I am also
interested in features that you think are equivalent or readily achieved
in each.

(2) The two major software packages explain their orientation as
follows: EPrints puts a particular emphasis on OA content (preprints
and postprints of institutional research output, plus theses), DSpace
on digital curation in general. Fedora describes itself as repository
storage layer software requiring custom front-ends for any purpose. If
you have any specific comments on these overall orientations and
whether they are appropriate, they would be very helpful too.

(3) While all these packages are free and open source, I would also
be interested in any cost estimates in implementing the one you chose,
how many hours or dollars you spent on setup, how much maintenance you
have to expend, and how reliable the software is (crashes, downtime,
etc). Would you recommend it to someone else?

I will post a summary of the results (and maybe an interim report) on AmSci
OA Forum, and may get back to you if I reed a bit more detail. Thank you in
anticipation of a prompt response and a flood of emails. Email direct to me
at Arthur.Sale@utas.edu.au if you want.
