-----------------------------------------

I haven't had a chance to look at the new development in trunk. Will do that today.

>                 Key: HHH-3614
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3614
>             Project: Hibernate Core
>          Issue Type: New Feature
>          Components: envers
>            Reporter: Corneil du Plessis
>
> I would like to suggest a new feature for version tagging in envers.
> I have a suggestion for how it can be implemented.
> @Versioned
> @Taggable
> public class MyEntity {
>      @Id
>     private Long id;
>     @Basic
>     String someProp;
> }
> By implication results in @RevisionTagEntity which can be seen as
> public class MyEntity_tag {
>     @RevisionNumber
>     private Integer version_numer;
>     @RevisionTagTimestamp
>     private long tag_date;
>     @RevisionTagValue
>     private String tag; // Other @Colum can apply as well as using Integer or Enum 
>    // Other properties allow like with @RevisionEntity
> }
> This produces a table like:
>     create table MyEntity_tags (
>         id bigint not null,
>         version_number integer not null,      // version_number is _revision
>         tag_date timestamp not null, // assigned when create or modified 
>         version_tag varchar(255) not null,  // Could be customizable with RevisionTagEntity similar to RevisionEntity
>         primary key (id, version_tag),
>     );
> EntityTagging will be a utility class using EntityManager and Entity or Collection of Entities and do:
> tagLatestVersion(Object entity, String tag)
> tagVersion(Object entity, Integer version, String tag)
> moveTag(Object entity, String targetVersion, String tag)
> determineVersion(Object entity, String tag)
> The following could be added to allow the retrieval of versions of collections of entities that are tagged in a specific way.
> RevisionProperty.tag(String tag)
