I'm creating an annotated corpus of poetry annotated with accent, alliteration, rhythm, and phonetics. I'd like it to handle and input poetry in multiple languages but still be able to add markup (perhaps in layers) for the phonetic markings.
It sounds to me like an XML database with a front-end tool for entry and another one for display and concordance. But it also sounds like something that must already exist somewhere. Who knows what software is already available and which ones are free?
