Dspace failed. Inestigated, no obvious reason why it failed. Restarted,

Buddy Tignor curious about how/if/why/ehen Google finds images in Dspace. Pointed him to Google FAQs, adjusted the robots.txt on badger. Google has found at least 2900 images on badger.

Spent considerable time yesterday and today watching and analyzing output from the lsof command, which showed a mess of  open assettstore files that never seemed to close.
After repeated writings to the Dspace-tech community, I finally received this from Richard Rogers <rrodgers@MIT.EDU>
I took a quick look through the code, and did note one oddity:a file stream [...]

Dspace died again. Same problem
This time, I tried a different fix: in the tomcat startup script, I added
    ulimit -n 4096
to set the number of allowed open filehandles way above the default of 1024
We’ll see what happens

SLow going as i wade through the metadata in the dtaatbase and figure out where it goes in Dspace Dublin Core implimentation. Think I fiannly have it down now, so onto the coding I go, when I realizie that there is another major disconnect between current GLCP practices and Dspace implimentation.
You see, Glcp has one [...]

Mapping Geology Landscape Change Program dtabase fields to Dublin Core metadata elements in anticipation of  insert a subset of GLCP records in Dspace. Not an easy roadmap, needed to consult many references and :best practices" This one especially helpful, as was this Dspace memo.

Dspace died again. Analyzed logs, made some changes to robots.txt, checked how often cronjobs (especial media filter) were running. Restarted, we’ll see how long it runs now.

Keeps dying with a "Too many open files" message
Seems related to high number of simultaneous page views, perhaps from a robot?
Experimenting with robots.txt, enabled access_log, need to watch logs and patterns
dspace-tech list has been no help.

The last bits of the puzzle.

Wanted to force users ths SSL port for login, but not necessarily for anything else
Wanted LDAP authenticated users forced into the UVM group, so that collections private to UVM could be accessed by NetID and password

Solution to both was found in SimpleAuthenticator.java and MITAuthenticator.java Combined both into UVMAutheticator.java, using MIT [...]

Create/alter aliases dspace-last and dspace-current to reflect new /usr/local/src directory structure
compare /usr/local/src/dspace-last/conf/dspace.cfg to /usr/local/src/dspace-last/conf/dspace.cfg, merge
copy extra jar files from dspace-last/lib to dspace-current-lib:

cd /usr/local/src/dspace-current
cp ../dspace-last/lib/jai_* lib
cp ../dspace-last/lib/mlibwrapper_jai.jar lib
cp ../dspace-last/lib/postgresql.jar lib

Remove the old version of xerces.jar from your installation, so it is not inadvertently later used:
[...]

As mentioned here, it has been decided (well, sort of) to pursue evaluation of Dspace as a content management system for the Landscape Chaange project.
Some issues and answers

can Dspace do the job?
Yeah, probably — but this is what the evaluation is all about

Why Dspace?
Any image repository/content [...]
