FYI we are having discussions with Sun about integrating DSpace with
their Honeycomb CAS system. However, the approach I am advocating is to
build an SRB compatibility layer/driver/translator for the product, and
so insulate DSpace from the specifics of the Honeycomb API. Contact me
if interested.

Hi Robert,
* Does DSpace have service devices (like SOA or SOAP)?
Yes, for submission (see
http://wiki.dspace.org/index.php/LightweightNetworkInterface).
* Is it correct that DSpace does not have an internal storage
management, which would mean (e.g.) to compress documents which are not
accessed for a given period, or to move them to an other storage
location (e.g. a tape server) if the last access is much older?
You can implement any storage layer underneath DSpace using the storage
API. There are implementations now for the local filesystem (the
default), SRB and S3 (in prototype, I believe). I think HP has also
implemented it with their HSM, but I don't know if there are other HSM
systems implemented now.
* And is it possible to bundle / relate different versions of the same
document, e.g. preprint and postprint?
This is handled now via metadata. For MIT's method of doing this see
http://wiki.dspace.org/static_files/f/fa/DSpace_Versioning_Feature_Summary_(July_2004).pdf
There are plans to change the DSpace data model in a future version so
that it can handle versions directly within an item. This is described
on the wiki (http://wiki.dspace.org/index.php/ArchReviewSynthesis). A
lot of this work has already started, and the plan is to complete these
changes in 2008.
* Does DSpace keep track of different versions of the same document to
have a history of minor changes (compared to pre- and postprint)?
It is a digital archive rather than an authoring system, so no, minor
changes to documents are noant normally kept. The idea is to store final
versions of documents and keep them forever, and to link different
*editions* of documents via metadata (see the last answer) so that users
can safely cite a particular version and not worry about it disappearing
later.
