Myles Megyesi has a good post called "Data Validation in Clojure"
http://blog.8thlight.com/myles-megyesi/2012/10/16/data-valid...
Megyesi points to this library:
https://github.com/mylesmegyesi/metis
"Metis is a library for data validation in Clojure inspired by Active Record Validations."
There is also Formative:
https://github.com/jkk/formative
"Web forms for Clojure and ClojureScript - rendering, parsing, and validating"
Pour:
https://github.com/Kaali/pour
"[Validates] form fields to specified constraints/validators and also to convert incoming fields, which are strings, to valid data in the application domain."
Validateur:

What I would like to know is which of these are good, and wha

t makes each different from the other. I have not had time to test all of these libraries, and there is no one library that has emerged as the dominant one in the Clojure eco-system -- rather, we are still at the point where everyone is doing their own thing.
Sandbar is more of a full framework but includes form handling:
https://github.com/brentonashworth/sandbar
Noir also handled form input but Noir is now deprecated.
The Clojure eco-system prefers small libraries as opposed to large frameworks, and that is a good thing most of the time, but in the case of form validation I have had a difficult time determining which libraries might be interesting to use.
