Description

In MySQL the column that are boolean are modeled via bit(1) or byte(1).

When I am using Olingo/Jpa beside MySQL and generate the entities in the Eclipse, it will assign type byte to these columns. It means in the metadata we will have something like this:

<Property Name="Deleted" Type="Edm.Byte" Nullable="false"/>

How can I modify the EDM type like the following?

<Property Name="Deleted" Type="Edm.Boolean" Nullable="false"/>

What I want to do is to do this modification with a mapping file, something like what explained here. (By this tutorial we can only change the names and not the types!)

Please note that I make eclipselink-orm.xml also automatically. I don't want to modify this file but it seems the type can be changed there as it has a line like this:
 

<basic name="deleted" attribute-type="byte">

However I don't want to modify this file each time while I generate it via Eclipse. Is there anyway that I extend some attributes there and inherent the rests?
