Andy Jefferson commented on JDO-652:
------------------------------------
FYI, DataNucleus also now supports methods on geospatial types.
http://www.datanucleus.org:15080/products/accessplatform_5_2/jdo/query.html#jdoql_typed_methods_geospatial
though this requires use of the DN-provided "javax.jdo.jar" rather than Apache
JDO "jdo-api.jar".
Whether support for these types (and the associated query methods) can one day
be standardised is left to people to request/discuss. The OGC standardised
simple geospatial types a long time ago, as per
[http://www.opengeospatial.org/standards/sfa] and DataNucleus has had full
support for them since day one. These JDOQLTypedQuery expressions map directly
on to the types they define.

> There are various querying capabilities of this type around. JPA2 has its
> Criteria query API. Third party solutions like QueryDSL also exist, in its
> case providing a JDOQL implementation (as well as JPQL, and HQL). We should
> seriously consider introducing something along these lines in the JDO2.4
> timeframe.
> There is a comparison of JPA Criteria with QueryDSL over at
