Please help locate a category for Informative site with RSS feed

I have a site that I would like to add to the ODP, which offers useful information that I have compiled, relating to CAD design and CAD engineering. (this is the knowledgebase for our site, with a glossary of terms, and an FAQ)

My site has already been submitted, under the parent URL. However, this portion of the site has its own sub-folder, and changes the scope from purely commercial, to purely informative.

The nicest part (in my opinion) is that the information in this section of the site is available to anyone - regardless of whether they do business with our company or not, and it's available in RSS and ATOM feeds.

I have searched the ODP, and have not found an appropriate category. Perhaps it's something that I have simply overlooked, or somewhere that I have not though to look. Could someone please give me some suggestions? A fresh perspective is highly appreciated.

Thank you.

RSS feeds are included in each category along with HTML pages and PDF files.

There are no specific categories for RSS feeds.

Should a person who is submitting a site, submit it under the RSS feed, as well as the html? Or is this something that is best left to the editor of the category to find out?

Thank you.

Submitting both to the same category would probably not be a Bad Thing.
