> I don’t think we need to specify the contents of the metadata classes, Well the JDO spec needs to specify enough to define that each persistable field in the PersistenceCapable class will have an equivalent public final XXXExpression field; (where the XXXExpression is one of the javax.jdo.query.XXXExpression classes), so then we know what expressions we have for use in the JDOQLTypedQuery for that class. Similarly there are methods required in the Q class to get the candidate/parameter of this type/variable of this type. Certainly the JDO spec doesn't need to define how these methods are implemented though, just that they exist. > but we should standardize the process to generate these metadata classes. OK. But apart from saying that an annotation processor will be provided by the JDO implementation, (and maybe giving an example of how to do that), what else would be standardised? > Do we need to standardize the handling of Java8 date/time types? +1 from me, certainly as Java 7 is EOL.
