Annotation Lexicon (ALex)
Allows for the management of information based on dynamic information hierarchies. This is a Java library that interacts with a MySQL database to provide for the creation of information schemas and the input of information based on those schemas.
The Annotation Standard Authoring Tool (ASAT) is the web interface that allows for the management of the annotation standard hierarchies and controlled vocabularies. The administrator defines the standards for which users can create annotation sets.
The User Annotation Authoring Tool (UAAT) is a web interface that lets users create and manage their annotation sets. The interface is dynamic, built using the Mini Ajax Library.
I'm no longer the primary developer of this project, but I do provide consultations on its development and usage every so often.
