I run a couple of newssites powerd by Filemaker 6 (I am still using CDML) an would like to offer a RSS-feed for the visitors. What is the best way to create and serve the requierd XML-file with updated headlines.

I have never used XML before so I

This should be easy to do with CDML, although doing it with XML/XSLT is more convenient

Start with these two articles:

What is RSS? by xml.com

RDF Site Summary (RSS) 1.0 specification

Try to build a CMDL page that would output similar code, with your CDML replacement tags that fill in the content of your news database. As the RSS link, offer a CMDL query (http://mynews.com/FMPro? ... ) that say queries for the last three news, or the news of the current date, or ... (it's up to your ideas).

And then, before going public, do a guess: How many RSS clients would connect to your web site, how many queries does your server have to handle, if say the RSS readers are configured in average to update every 15 minutes, every 30 minutes? How would this affect performance? Would you need to have a RAIC? Or switch to FMS7A ?
