Overview

The Metadata class holds meta data associated with a SCORM package in a hash like structure. The Metadata class reads a LOM (Learning Object Metadata) structure and stores the data in categories. A Category can contain any number of +DataElement+s. A DataElement behaves just like a string but can contain the same value in many different languages, accessed by the DataElement#value (or DataElement#to_s) method by specifying the language code as the first argument.

Ex.

<tt>pkg.manifest.metadata.general.class -> Metadata::Category</tt>
<tt>pkg.manifest.metadata.general.title.class -> Metadata::DataElement</tt>
<tt>pkg.manifest.metadata.general.title.value -> 'My course'</tt>
<tt>pkg.manifest.metadata.general.title.value('sv') -> 'Min kurs'</tt>
