Caroline,
I have set up a server so you can see how it works.
http://mlweg.pc.ee.usyd.edu.au:8080
Just go there and login as follows:
email: mailto:random@striker.com
pass: random
Then just proceed to:
http://mlweg.pc.ee.usyd.edu.au:8080/random/index
There, you can read about more about the process for uploading IMS/SCORM Content Packages.
There is an IMS CP package there, but I just added an SCORM on the file-storage as well (so you can upload SCORM packages too and test how it goes about uploading 250+ dirs and files)
http://mlweg.pc.ee.usyd.edu.au:8080/files/view/package.zip
The IMS MD part works very well as well, but I haven't done an interface so you can see it on the web.
Comments, questions and suggestions are more than welcome
Ernie
