===About The SourceCode===

[https://developer.mozilla.org/en/mozilla-central Mozilla-Central] is the main repository for Mozilla source code. This is the raw fodder out of which documentation will be created. How it is created doesn't really appear on our diagram unless you count the "How does this happen?" note.  Well, how it happens is through a static analysis tool called [https://developer.mozilla.org/en/Dehydra Dehydra]. In layman's terms, Dehydra reads the Mozilla source code and annotates it in a way that can be turned into documentation in an automated fashion. This part is another project entirely and as it relates to our project, the relevant work is being done by David Humphrey. However, our team will need to setup the Dehyra tool to feed our update server. (More on that in a moment.) David has assured us that this part is not a huge job. It might be useful to sit down with him sometime in the near future and get our own development setup running to play around with and use for research. (David has a setup, but we wouldn't want to muck it up.) For now, let's just take it as read that the Mozilla source code has been processed and fed to the update server.

Although this project is all about building a tool for browsing documentation off-line, that documentation is in a constant state of flux. It would be useful to be able to refresh it when need be. The update server needn't be terribly complex. A simple Apache server and some cgi CGI work should suffice.  However, it needs to be worked out exactly what kind of update is being pushed. Is it a binary diff of the sqlite database? And if so, will it need to keep a collection of diffs based on a original dataset in order to service users who haven't sync'd for some time. There's also the question of whether the update mechanism build into Mozilla for extensions is useful to us. We need to do some research on how extension updates work.

The front-end Portable DXR (our browsable source code documentation) is an applicationthat lives inside our extension. It's The CGI tools exist as part of an embeddable web server. When you remove the DXR part, what you are responsible for communicating left with is the core application platform on which it runs. It's also worth pointing out that the SQLite support is available in two ways. Local storage capabilities using SQLite are build into Mozilla applications and fetching can be accessed by an extension using C++, JavaScript, Python. However, SQLite database files can be accessed by any software that understands the data to format, so SQLite support will also be available through the applicationcgi tools. The DXR application then parses will probably use the CGI tools to access SQLite files if our presentation layer is traditional XHTML. But if we decide to use XUL, we can use the data and populates browser's built in functionality directly from JavaScript. In either case, I suspect we will end up leveraging the built in sqlite support for the UI as neccessaryupdates. But we need to do some research on that.

The core application has presentation. The front-end is mostly implemented by [http://vocamus.net/dave/ David Humphrey] on his [http://zenit.senecac.on.ca/wiki/dxr/ DXR]. We need to modify the UI to implement the following functionalities:* Navigation
