This project just popped up on my radar - Canonical Entity Representation (see http://groups.drupal.org/node/197588 and http://groups.drupal.org/node/197583). The description of this sounds like it would resolve one of the key critiques I have against Drupal. Namely the lack of a import/export format that's part of Drupal Core. I'd like to call some attention to this and hopefully, as the two posts above suggests, this can be a standard part of Drupal starting with v8.
