LomPad is a Metadata generator for Windows, Mac and Linux that will simply generate all the metadata you need, either to the IEEE standard LOM (Learning Object Model) profile or, specifically for many of us, the SCORM 2004 profile.
It’s pretty straight up and easy to use so far. I’m looking forward to putting it through its paces. It’s default language is French, but there is support for English that you can turn on pretty easily from its menu options.
