Overview

Class to build source representations of ActiveSource objects. Talia uses a simple XML format to encode the Source Object. The format maps easily to a Hash as it is used for the new or write_attributes methods:

<sources>
  <source>
    <attribute>
      <predicate>http://foobar/</predicate>
      <object>http://barbar/</object>
    </attribute>
    ...
  </source>
  <source>
    <attribute>
      <predicate>http://foobar/bar/</pedicate>
      <value>val</value>
      <object>http://some_url</object>
      <value>another</value>
      ...
    </attribute>
    ...
  </source>
  ...
</sources>
