Cross Browser, Object Persistence Library for Client Application

Question

I'm creating a client based application in HTML Application (HTA) and I would like to know if there's a object persistent library similar to python's shevle that meets the following criteria:

• Should be able to read and write on file
• Cross browser: should work at least on both HTA and on Firefox (through XULRunner) so that I'll be not tied to any vendor.
• Written in JavaScript form

TiddyWiki is able to save itself, regardless of the browser used, though the codes that saves and retrieves files has to be refactored to meet my need.

Answer 1

Well, I wasn't aware that TiddyWiki has a github repository, and they organized the files by module.

I could just take the FileSystem.js file and build a nice api on top of it to simulate shelve functionality.
