  /* KABC Birthdays are got through a ItemSearchJob/SPARQL Query
   * I then added an ETM/CalendarModel because we need to search
   * for calendar entries that have birthday/anniversary categories too.
   *
   * Also, we can't get KABC Anniversaries through nepomuk because the
   * current S.D.O doesn't support it, so i also them through the ETM.
   *
   * So basically we have:
   * Calendar anniversaries - ETM
   * Calendar birthdays - ETM
   * KABC birthdays - BirthdaySearchJob
   * KABC anniversaries - ETM ( needs Birthday Agent running )
   *
   * We could remove thomas' BirthdaySearchJob and use the ETM for that
   * but it has the advantage that we don't need a Birthday agent running.
