Cornweb is an umbrella project for four separate libraries, each dedicated to a different part of Web development:
Depot: Basic WSGI application framework, built to handle the routing of URLs and dispatch of requests Backfire: High-level wrapper atop Depot for building sophisticated Web applications. It includes facilities for the integration of Genshi and SQLAlchemy, as well as the encapsulation of common application behaviors, such as pagination and form processing. Formosa: Processing of user input to Web applications. Unlike most other form processing packages, Formosa allows for declarative, higher-level constraints on user input. Facade: Library for the generation of interface markup using Genshi. Facade helps to automate the most repetitive parts of HTML user interfaces, namely forms and pagination. These libraries were written after the development of the Chromatin Consortium Database (CCDB), an information system for a multi-institutional genetics project. Having implemented CCDB in Ruby on Rails, it was found that Rails failed to scale to the complexity required by such a project. These libraries were designed based on those lessons learned.
