Basic model of the EML

The following sections describe the UML classes that represent the core structures of EML. In the following sections they are introduced using UML class diagrams. In the text descriptions, a class (property) is referenced by a name prefixed by underscore, e.g. _class and _class.property. The EML structure is centered around the concept of a 'play'. Most of the components are named after the elements in the EML specification; some have been added to model implied constructs, such as 'task', and others have received a more explicit name, such as 'property'. This however does not alter the fundamental mapping of the EML to the model presented.
