There is WebAnno [1], which uses the brat Javascripts to render/edit 
annotations in the
browser and which uses the UIMA CAS in the backend. Currently, WebAnno supports 
only a 
subset of the DKPro Core type system. We are currently working on 
user-definable types
though.

Data can currently be imported/exported in e.g. in CoNLL 2006 format. We do not 
support
the Brat data format yet, but if you cook up something under the Apache 
License, we may
actually adopt and adapt that ;)

If you are interested, there is a standalone JAR version available for a quick 
test drive.

Cheers,
