eWRT (extensible Web Retrieval Toolkit)
eWRT supports the consortium in all data collection tasks. In addition to retrieving data from social networks (like Facebook or Twitter), it provides helper classes for effective caching and data management.
For instance, weblyzard_api builds upon some of its components.
Start by downloading the latest version from Github and by reading the documentation at Read The Docs.
