Andy Jefferson updated JDO-615:
-------------------------------

    Attachment: jdometadata-4.patch

Updated javax.jdo.metadata :-
1. Remove many enums dupd from annotations, as per my previous comments on this JIRA
2. Renamed FileMetaData to JDOMetaData
3. Added FetchPlanMetaData
4. Added many sub metadata components
5. Changed add/set methods to do the creation of metadata objects as per Craig comments.
6. Updated MetaDataManager to fit above (still has creator for JDOMetaData currently but this could move to JDOHelper at some stage)

> We can specify MetaData via XML or annotations. The only way missing is via an API. I propose mirroring the XML structure with interfaces of the form
> public interface MetaData
> {
>     addExtension(String key, String value);
>     removeExtension(String key, String value);
>     ...
> }
> public interface FileMetaData
> {
>     addPackage(PackageMetaData pmd);
>     ...
> }
> public interface PackageMetaData
> {
>     addClass(ClassMetaData cmd)
>     ...
> }
> public interface ClassMetaData
> {
>     addField(FieldMetaData fmd)
>     ...
> }
> public interface FieldMetaData
> {
>     setInheritance(InheritanceMetaData inhmd)
>     ...
> }
> and so on.
> We would then require a method on the PMF to register the metadata.
> If there are no objections to such a feature I'll propose a patch to try to provide all current JDO2 capabilities.
