Hi,

We are migrating an existing application and we want to handle all NHibernate classes / mappings in a uniform way.
In the database, (allmost) all tables have the same base-fields, that is a primary key, a version and a tenantid.
In .NET we created a base class with these fields, all real classes derive from this class, like:

class Entity
{
public int Id;
public int Version;
public int TenantId
}

class Table : Entity
{
// Table specific fields go here
}

We create mapping for all real-classes, but for now we have to specify these Entity-attributes explicitely in every class-mapping, like e.g.

<class name="Table" table="Table">

<id name="Identity" type="int" column="Id">
<generator class="identity"/>
</id>

<version
column="Version"
name="Version"
access="property"
unsaved-value="negative"
/>

<property name="Tenant">
<column name="TenantID" not-null="true" />
</property>
<!-- other properties go here -->

</class>

My question: is it possible to extract the lines marked in blue and import them in every real-table mapping?

Any hints are greatly appreciated

Kind regards,
