Core Concepts

The functionality provided by the Polymatheia library is built around two concepts:

• The NavigableDict as the data-structure used to store all data in the library. The NavigableDict is a simple extension of the standard dict that allows for access to the values via dot-notation:

  record = NavigableDict({'one': '1', 'two': {'one': '2.1', 'two': '2.2'}})
  record.one      # '1'
  record.two.one  # '2.1'
  

• All data readers, the filtering, and transformation classes are all designed as iterators, allowing them to be chained together however required.
