Craig Russell updated JDO-403:
------------------------------
Attachment: embedded.patch
I've looked at how to map embedded map keys and values, and by changing the embedded() from String to @Embedded[ ] and adding embeddedKey, embeddedValue, and embeddedElement to @Field and @Property, here is some sample code that compiles ok:
@Field(table="INTEGER_LINES", embeddedKey="true", embeddedValue="true")
@Join(column="OWNER_FK")
@Key(column="INTEGER")
@Value(
embedded=@Embedded(
fields={
@Field(name="point1.x", column="POINT1_X"),
@Field(name="point1.y", column="POINT2_Y"),
@Field(name="point2.x", column="POINT2_X"),
@Field(name="point2.y", column="POINT2_Y")
}))
Map<Integer, Line> integerLines;
@Field (table="LINES", embeddedElement="true")
@Join(column="OWNER_FK")
@Element (
embedded=@Embedded(
fields={
@Field(name="point1.x", column="POINT1_X"),
@Field(name="point1.y", column="POINT2_Y"),
@Field(name="point2.x", column="POINT2_X"),
@Field(name="point2.y", column="POINT2_Y")
}))
Set<Line> lines;
I think it's pretty true to the xml concepts. What do you think?

> It would be desirable for JDO2 to have its own set of annotations. We have developed a set within JPOX that would likely serve as a starting point for such a set. In my opinion they should be
> 1. Split into javax.jdo.annotations.jdo and javax.jdo.annotations.orm
> 2. Move ORM attributes from some of the JDO annotations and have a ORM annotation.
