Notes

• The list of SOIF attributes was generated by Simon Wilkinson based on the contents of his .glimpse_attributes file, and by looking through some of the summarisers. It may not be complete.
• The Dublin Core sub-elements listed above are still under discussion on various mailing lists. See <URL:http://www.loc.gov/marc/dcqualif.html> for a fairly up to date list.
