Entities in the archive domain graph

For PolicyCenter to consider an entity as part of the archive domain graph, that entity must implement one or more delegates. A delegate adds an interface and a default implementation of that interface to entity types that implement the delegate. Some delegates also add columns that the delegate implementation manages. The archiving delegates help define the extent of the archive domain graph and are necessary for successful operation of the archive process.

Warning: Do not change or remove the archiving delegates on Guidewire entities in the base configuration. Otherwise, it is possible for the PolicyCenter server to not start due to errors in the archive domain graph.

In addition, any new entity that you want to add to the archive domain graph must have an ownership relationship with another entity already in the graph. You can establish ownership in one of the following ways:

By defining a foreign key in the new entity to another entity already in the graph.
By defining a foreign key to the new entity from an entity already in the graph and setting the attribute archivingOwner="source".

The following table summarizes the entity types that exist in the archive domain graph.

Entity type	Delegate Implementation	More information
Graph root entity	The root of archive domain graph must implement the `RootInfo` delegate. You cannot change this designation. For PolicyCenter, the RootInfo entity is `PolicyPeriod`.	Archive entities and the RootInfo delegate
`EffDated` entities	Entities in the PolicyCenter archive domain graph implement the `Extractable` delegate through the `EffDated` delegate.	Archive entities and the EffDated delegate
Overlap table entities	Overlap tables are tables in which individual table rows can exist either in the archive domain graph or as part of reference data, but not both. The database table itself exists in the archive domain graph and as reference data. All overlap table entities, and only overlap table entities, must implement the `OverlapTable` delegate. In PolicyCenter, only `Note` and `Document` entities implement the `OverlapTable` delegate. The primary use for these types of entities is for Guidewire code. The use of overlap tables by non-Guidewire code is not common.	Archive entities and the OverlapTable delegate

Graph root entity

The root of archive domain graph must implement the RootInfo delegate. You cannot change this designation. For PolicyCenter, the RootInfo entity is PolicyPeriod.

EffDated entities

Entities in the PolicyCenter archive domain graph implement the Extractable delegate through the EffDated delegate.

Overlap table entities

Overlap tables are tables in which individual table rows can exist either in the archive domain graph or as part of reference data, but not both. The database table itself exists in the archive domain graph and as reference data. All overlap table entities, and only overlap table entities, must implement the OverlapTable delegate.

In PolicyCenter, only Note and Document entities implement the OverlapTable delegate.

The primary use for these types of entities is for Guidewire code. The use of overlap tables by non-Guidewire code is not common.
