            my $chain = DataFlow::Chain->new(
                    DataFlow::Node->new(
                            process_item => sub {
                                    ... do something

# DESCRIPTION

This is a framework for data flow processing. It started as a spinoff project from OpenData-BR.

As of now (Mar, 2011) it is still a 'work in progress', and there is a lot of progress to make. It is highly recommended that you read the tests, and also the documentation for DataFlow::Node and DataFlow::Chain, to start with.

An article has been recently written in Brazilian Portuguese about this framework, per the São Paulo Perl Mongers "Equinócio" (Equinox) virtual event. Although an English version of the article in in the plans, you can figure a good deal out of the original one at

Any doubts, feel free to get in touch.
