The following modules are required for the program to be succesfully executed:

• re (For regular expressions)
• urllib2 (For url / request parsing)
• json (For pretty printing objects as json)
• BeautifulSoup (For html parsing)
• 'request' (For Unit Testing)
• ``unittest` (For Unit Testing)

Simply returning the following at the command line should install these for you:

> python setup.py

The following command should run the program:

> python model.py

The program follows a simple OOP architecture and the fundamental operations are called using a class mechanisim that adopts multiple methods through inheritence.

The Base Class: Scrape()

Class Methods:

- `retrieveData(self)`
- `getProdAttr(self)`
- `getProdUri(self)`
- `getRequest(self)`

Global Objects: json_obj, product_attr

Each method communicates with eachother and recursively returns objects for each method to communicate and interact with.

Some Unit Testing has been implemented and can be found within the test_module.py file.

The following modules need to be installed on your system:

• unittest
• request

After installing both unittest and request, the testing program can be executed by returning the following command:

> python -m unittest test_model
