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.
