 The model includes two additional entity types: <strong>qualifiers</strong> and <strong>annotations</strong>. These are both structured as sets of attribute-value pairs.
  <ul><li> Qualifiers can be associated to relations, namely <strong>use</strong> and <strong>wasGeneratedBy</strong>, in order to further characterise their nature. <strong>Role</strong> is a standard qualifier.
-<li>  Annotations are used to provide additional, "free-form" information regarding <strong>any</strong> construct of the model, with no prescribed meaning. The difference between attributes and annotations is further clarified <a href="#expression-annotation">here</a>.

-Attributes and extensions are the main <strong>extensibility points</strong> in the model: individual interest groups  are expected to extend PROV-DM by introducing new sets of attributes and annotations as needed to address applications-specific provenance modelling requirements.
