XPATH Vs OQL Query comparison

[Farrukh Najmi <Farrukh.Najmi@east.sun.com>]

We just concluded an exercise of mapping our most complicated ad hoc
query (Classification query) to XPATH. Also attached are some pictures
of attendees.

OQL Query
------------
SELECT DISTINCT eo FROM ExtrinsicObject WHERE
eo.isClassifiedBy(ClassificationNode(path: “Industry.Automotive”)) AND
eo.isClassifiedBy(ClassificationNode(path: “Geography.Asia.Japan”));

XPATH Query
---------------
Thanks Mike Rowley and Chris for doing this.

//ManagedObject[@uuid = /classification[@targetObjRef=

/ClassificationNode[@name="Industry"]

/ClassificationNode[@name="Automotive"]]/@sourceUUID]
                            %AND% @uuid = /classification[@targetObjRef=


/ClassificationNode[@name="Geography"]

/ClassificationNode[@name="Asia"]]/@sourceUUID]


What are some thoughts on which representation is simpler from the
person writing teh query in an RR client?
