I want to start new project customCms, cause I think it's a good starting point to implement my collected knowledge from c#, ddd, nhibernate, mvc3, js.

It will be great if I hear some guidlines from expirienced users here. I will use C# ASP.NET MVC3 razor view engine. Also I was thinking of NHibernate ORM, I dont know if using Nhibernate will cause performanse down. Initially MSSQL 2008 will be used, but using ORM layer cause that I can switch to some other db with no pain.

I was thinking to create News entity which will have properties

Id
Name
Created
Updated
IntroText
Content
Title
Author
ListPhotos

Every input will be validated with untroub. java script on the view, and it will be validated on db level as well.

Maybe it is best approach to create some interface which will be implemented by my cmsClient entity like NewsEntity. In this interface will be included everything it should be requested from my client in future. At least some stuff which are not included in entity right now, consumed data by rss feed, wcf, etc.

So basically everything you think its good idea from documentating project, to coding. Everyone is welcomed to brainstorm for custom cms.
