Creating an XML or JSON feed for another website


I'm interesting in creating a feed from an Omeka site to a website designed to take advantage of the conveniences of a smartphone, particularly the GPS function.

I understand that the best way to do this would be to create a JSON or XML feed, but I'm not quite sure how to do this. Does anyone have any experience doing this?

Omeka can already produce feeds from a sitein several formats.

For information about what those formats are and how to access them, see the Omeka Codex page on response formats.

This looks interesting topic, I am thinking that I can also have the same idea. I am seeing the output formats, but are these one have a drop down list/menu features? I don't know if my web designer from will have like this features. Thanks for the simple tips anyway.
