there is also the RSS 1 module
http://web.resource.org/rss/1.0/modules/syndication/

sy:updatePeriod
"Describes the period over which the channel format is updated. Acceptable
values are: hourly, daily, weekly, monthly, yearly. If omitted, daily is
assumed."

btw, if you don't know it, http://lov.okfn.org/dataset/lov/ is a really
handy vocabulary search engine.
