Hi,

I'm making substantial changes to the Import screen to support
interactive imports e.g.
http://trac.eprints.org/eprints/browser/trunk/system/perl_lib/EPrints/Plugin/Import/ISIWoK.pm

I've not finalised the API but the idea is this:
 - Import plugins can do any of 1) free-text input, 2) file-upload
input, 3) HTML form input.
 - Import data is converted into epdata and stored in a cache table
 - User can select from the available objects to import individually or
"import all"

The responsibility of the Import plugin is to query the remote service
(optionally with a record offset), convert the resulting records into
epdata and tell the Import screen the total number of records.


At the moment it's a bit of a kludge because the existing import assumed
that the import would be a one-shot process (vs. interactively querying
a remote service) and would only import into one dataset.

But anyway ... you may want to work on the trunk version of EPrints,
then think about how to back-port.

All the best,
Tim
