The problems with the adoption and implementation of the previous versions of the LOM are apparently solved by the addition of more definitions of structured taxonomy-driven authoritative metadata systems.
I'm posting this to remind myself to not get sucked into this stuff. It's good that people are thinking about how to improve on the LOM, and even deprecating the term "learning object" (replaced by "resources") but for the love of all that is holy and good, please focus on the content, context, and pedagogy and not on the metadata.
Whew.
