######SECTION ONE: code structure The code is organized in three packages, following the schema used during the lab lessons:

1. the model package, containing the model objects, namely HealthProfile and Person java classes;
2. the dao (Data Access Object) package, containing the Storage class, used as a data storage when marshalling/unmarshalling;
3. the default package, containing a class for every "main" action to be performed: Jsonizer, Mymarshaller, Myunmarshaller, XpathGetter.

######SECTION TWO: code insight Launching the classes in the default package with the appropriate arguments, the requested tasks will be performed. XpathGetter retrieves the data from the people.xml file, associated to people.xsd, while Mymarshaller and Myunmarshaller marshal/unmarshal the People (and therefore HealthProfile) class to/from the marshalperple.xml file. The Jsonizer print its output to people.json.

######SECTION THREE: run the code To run the code and have the requested tasks performed, simply run ant execute.evaluation script in the project home directory. It is also possible to run the six tasks singularly, by executing ant execute.X, where X is an integer between 1 and 6 corrisponding to the task list in the website's assignment page.
