JDO 2.1 is in progress, adding on annotations, enums, JDOQL subqueries, support for some JPA concepts, and other things. JDO 2.1 is even more of a superset of JPA now than JDO 2.0 was before. There are implementations, just that only one (as far as I know) is JDO 2 compliant ... JPOX. JPOX (http://www.jpox.org) already has support for the majority of these JDO2.1 enhancements, together with the start of support for DB4O. JPOX is publicised on (probably) the main spanish-speaking Java website (javahispano.org) whenever we make releases, so you may have heard of it. The Apache JDO website doesn't seem to have been updated with anything about JDO 2.1. Perhaps someone from Apache JDO can get that done ? Some websites (e.g jdocentral.com) don't seem to be active now. You would have to ask the people behind it why and what their motivations are. While large organisations may want JDO to disappear (just like RDBMS vendors wanted it to go away during JDO 1), it is still alive (which is proven by the fact that there is a JDO2.1 making significant improvements) and there are implementations around. How committed some of the other implementations are to JDO 2.1 remains to be seen ... Un saludo de Reino Unido -- Andy (Java Persistent Objects - http://www.jpox.org)
