If we were to use dc.relation.replaces and dc.relation.isVersionOf to identify both the VersionHistory and and not dc.relation.isReplacedBy to resolve

Tasks needing to be completed To support Versioning of Items:

Database Schema

Task: Create Database changes to support version history/version, similar to Workspaceitem / workflowitem

Task: Document Database Changes here:

Domain Model and Data Access Support Changes

Task: Create Data access objects and domain model to get versions from database

Task: Document Domain Model Here

Task: Utilize ServiceManager to deliver Versioning Service to Application,

Task: Provide Examples of how Service Manager is used to get Service here

XMLUI Support

Task: We will create a new Versioning Aspect Project for changes to XMLUI

Extensible ItemAdapter

Task: Extend the ItemAdapter to have a "administrativeMetadata" section, it would be good if this was pluggable.

To get to here we need review the ItemAdapter overrides that are available in atmire-xmlui-api...

we will decide on more fields, document in the wiki page.

Rendering to HTML
