Hi Brandt

I am working on project between HP, MIT and W3C called SIMILE which is
investigating semantic metadata for libraries - see
http://web.mit.edu/simile/www. MacKenzie Smith, a PI on this project,
pointed out that Leeber is an open-source resource cataloguing application
using RDF. 

I have downloaded Leeber, but I am experiencing some difficulty getting it
to run. I have followed the install instructions, but in addition I needed
to make a number of changes. Firstly I'm running on Windows, so I had to
edit leeber.java to replace /var/leeber with /apps32/leeber.

0.  See the files in doc/examples for examples of the files you need to
create

Done, but not sure what I'm looking for. 

1.  Create a directory /var/leeber

Done - /apps32/leeber

2.  Put your RDF data in /var/leeber/data.rdf

I just copied data.rdf from doc/examples to here. Is this going to cause
problems?

3.  Create an empty RDF file /var/leeber/suggestions.rdf

Done

4.  Create an empty RDF file /var/leeber/users.rdf

Done

5.  Describe your portal(s) in /var/leeber/portals.rdf

Not sure how to do this. I think you need some more information in the
install instructions. I just copied portals.rdf from doc/examples to
/apps32/leeber/. I tried running Leeber / Tomcat, but it fell over because
it couldn't find "localhost" in this file. So I added

    <dc:identifier>localhost</dc:identifier>

in the first description after the namespace defintion. Is this sufficient,
or do I need to make other changes to this file also?

6.  Create a directory /var/leeber/vocab

Done

7.  Put RDF files for each RDF schema you will use into /var/leeber/vocab
    Name the RDF files X.rdf, where X is the schema namespace after
URL-encoding

I just copied the files from /doc/examples. Is this sufficient? The
filenames look horribly mangled on Windows, but judging by the console log
Leeber does seem to read them okay. 

8.  Create a directory /var/leeber/logs

Done

9.  Extract leeber and edit build.properties to match your system

Done

10. Build leeber using ant. This should automatically deploy leeber to
    Tomcat for you. You may need to restart Tomcat.

Done, although I can't get the auto deploy to work fully, but I don't think
this is a problem. 

11. Visit your portal page. Register for a new user account.

I start tomcat. I'm not sure where the portal page is, so I tried pointing
my browser at
http://localhost:8080/leeber/home/

However in the browser I get

Apache Tomcat/4.0.6 - HTTP Status 500 - Internal Server Error
