RDFa ok - adding structured data to MusicBrainz HTML to commence

  • user warning: Unknown column 'captcha_type' in 'field list' query: SELECT module, captcha_type FROM captcha_points WHERE form_id = 'comment_form' in /var/www/drupal/sites/all/modules/captcha/captcha.inc on line 64.
  • user warning: Unknown column 'captcha_type' in 'field list' query: SELECT module, captcha_type FROM captcha_points WHERE form_id = 'user_login_block' in /var/www/drupal/sites/all/modules/captcha/captcha.inc on line 64.

Last week during the MusicBrainz developer meeting, we presented some experiments about including RDFa in MusicBrainz HTML pages.  The results suggest that the page size (just the HTML file) will increase by between 5% and 30%.
