I'm afraid this is one of those "stick it into Description" answers. There is no specific DC data element that represents frequency of publication. In the DC Citation WG's recommendations, you can say in which month a particular issue is published (in the Chronology piece of the text string), and if you use a SICI in the Identifier field, you can infer the same thing, but what you can't say in either the DC-Citation string or the SICI is that the journal is published monthly. Therefore, a Chronology of "May" or "05" only tells you that the issue is a May issue - you'd have to look at the record for the previous and next issues to divine whether that made it a monthly or whatever. Doesn't this stem from DC's origins as a resource-discovery metadata set? It never was meant to cover everything you might want to say about a resource, and I don't think frequency of publication is a core *discovery* field.

Any ideas how to specify this in DC? Thank you for your answers.
