Hello,

I'm doing quite a few AIP imports on to prepare for a big migration we have
coming up and I was wondering how the XSD caching mentioned on the wiki[0]
works. I spent some time finding and downloading the correct .xsd files
(which is harder than it sounds) and added the changes to dspace.cfg, but
after doing a few rounds of testing I'm not sure it actually works.

First of all, the time to import a small collection hierarchy with ~200
items was the same with and without the XSD caching. Second, I did a
tcpdump during the import to see if I could track the repeated downloading
of XSD files for METS validation, but I only saw ~200 pings—one for each
iteration of the ingest loop!—to an update server belonging to one of the
Java components used in the AIP logic (which is both inefficient and a
violation of privacy, a subject for another time).

Does anyone have any insight? DSpace version is 5.5. Thanks.
