the tags are stored in the image itself

See xmp standard
http://ns.adobe.com/xap/1.0/

what you are looking for is stored in

dc:subject

tracker might also keep a list of tag data for photos, idk, would make things like filter by tag easier

here is the data in a photo I tagged using N9 with 'food' and 'tedt'
