HTML form management and validation

Flatland maps between rich, structured Python application data and the string-oriented flat namespace of web forms, key/value stores, text files and user input. Flatland provides a schema-driven mapping toolkit with optional data validation.

Flatland is great for:

• Collecting, validating, re-displaying and processing HTML form data

• Dealing with rich structures (lists, dicts, lists of dicts, etc.) in web data

• Validating JSON, YAML, and other structured formats

• Associating arbitrary Python types with JSON, .ini, or sys.argv members that would otherwise deserialize as simple strings.

• Reusing a single data schema for HTML, JSON apis, RPC, …

The core of the flatland toolkit is a flexible and extensible declarative schema system representing many data types and structures.

A validation system and library of schema-aware validators is also provided, with rich i18n capabilities for use in HTML, network APIs and other environments where user-facing messaging is required.
