You might try storing the text as JSON. You could use this plugin to move it in and out of C2:http://www.scirra.com/forum/plugin-load-json_topic50331.html
I think there's also some native support for JSON in arrays as of R87.
To make the data easy to deal with, you could create a database and have it spit out text chunks in JSON format. If you use something like Ruby on Rails...http://www.rubyonrails.org
...you could create a basic CRUD app to handle the data pretty quickly. When you're ready you could output the data into .json files which you could store in a folder alongside the C2 code. Or, if you can store the database online, you might be able to access it with AJAX requests. I don't know much about C2's AJAx capabilities, though.
There's some initial overhead with this method, but it would make data entry and keeping track of the structure much easier.
Edit: There's also XML support in R87, and Ruby On Rails will spit out XML as well. XML has lots more overhead than JSON, though.joeykid62012-05-02 10:08:22
