Hi Chris,

Good catch. I'll update the spec for the next go-around.

Thanks,

Craig

Not to belabor the point here, but reading on I see the following in section 2.2 ("Rationale"):

There is no existing Java platform specification that proposes a standard architecture for storing the

state of Java objects persistently in transactional datastores.

Not exactly the case anymore. I suggest this passage be updated (or eliminated) in light of JPA. Perhaps the statement could be amended to point out that there is no existing spec that proposes a *datastore-agnostic* standard architecture for persistence. This is probably the chief conceptual discriminator between JDO and JPA today. No flame bait intended on this thread, btw; I'm a JDO user and advocate. I mention these things because I believe it's in JDO's best interest to acknowledge JPA wherever appropriate, and distinguish itself and it's raison d'être wherever it can.

Craig,

The introduction's preamble reads:

Currently, aside from JDO, there are three Java standards for storing Java data persistently: serial- ization, JDBC, and Enterprise JavaBeans. Serialization preserves relationships among a graph of Java objects, but does not support sharing among multiple users. JDBC requires the user to explic- itly manage the values of fields and map them into relational database tables. Enterprise JavaBeans

require a container in which to run.

Thanks,

There's no mention of JPA here; I imagine there should be, as it is indeed a fourth standard. Perhaps it's out of scope or inappropriate, but it would be nice to see the spec 'officially' address the relationship between these two increasingly similar standards.
