Hi there,
We just wanted to let people know about a new open source project called NHDomainMapper,hosted in Codeplex at:

http://www.codeplex.com/Wiki/View.aspx? ... mainMapper

NHibernate Domain Mapper is a tool that assists user creating NHibernate Mapping Files. User may add his own Domain Model assemblies and map them to database table using a rich UI, which will present him all the suitable options regarding at the element type he created. The peculiarity of this tool is that it allows doing the mapping task starting from a domain model instead of a Database schema.
Feel free to download and try it out or contribute, and give us any feedback.
