Hi Andy,

It would be nice if we could have @Column("DEPARTMENT") instead of

specify more than just the column name you would have
@Column(value="DEPARTMENT" jdbc-type="BLOB")

I've no particular problem with that but would point out that when you need to i.e "value" and not "name" (and "name" is more logical when doing that)

I agree.





@Column("DEPARTMENT") and
@Column(name="DEPARTMENT", jdbc-type="DECIMAL(12,0)")

This might be controversial, but my Annotations Feature Request #3 is to allow the annotation to declare which element is the default if there is only one value specified. In this case, it would be "name". Without this feature request, we would define two elements: value() and name(). Your annotation processor would have to scold you if you specified both name and value; only one is allowed. That way, you could have both

Also @Field (column="DEPARTMENT")

to keep a clean divide between JDO and ORM.

I've no problem with adding that shortcut String property to @Field but would mention that several shortcuts were removed from non-ORM annotations to try

Could you possibly expand more on this?

On a related subject, previous discussion of @Table, @SecondaryTable,

@Column, maybe you're also thinking of
@Table("MYTABLE")

@JoinTable mentioned why is the table name "table" and not "name". I've absolutely no problem with it being "name" (and would make JDO2.1 annotations consistent with JPA1 in this respect). If contemplating the change above for which would mean the annotation property for the table name would be "value".

And name() as well as value(). See above.

possible since I want to get the next JPOX 1.2 beta out using them

It would be nice to get these into Apache JDO SVN by early next week if at all

Best,

Craig

Ah, deadlines. I'll see how much I can do in the next few days to wrap things up.
