Data::Manager is a really fantastic marriage of two very well thought out and uncoupled modules, Data::Verifier and Message::Stack. Data::Verifier does exactly what its name says, which is verifies data. You give it a hashref of constraints to verify against, and call ->validate on your data that you've passed in, and boom, data is verified with errors and filters. Messages::Stack is again, another very aptly named module. It gives you a programmatic interface to creating a stack of messages with a syslog flavor to them with regards to message level, scope, id, etc. You can then, after creating a stack of messages, retrieve messages matching a scope, or a block of messages pertaining to a certain attribute of your data, search through the messages and grab the ones that match your search criteria, or get all of the messages.
