Idea for a simple bib tool

I was using Zotero for my research readings, however, it is a bit too heavy for me, and I want a tool that can be portable across machines. So I am planning to write a bib tool for myself when I am a bit free sometime next spring.

The most important concept in this tool:

• Keep it Simple: there will NOT be fancy setup interface, but a config XML; there will not be many export styles for that is latex’s business.
• Depend less: there is already many advanced tools for bib organization, but they depend on this and that. I plan to implement all this tool with Python and sqlite3, so it can be put into U-key/Dropbox, and used anywhere.

The basci senarios is:

1. User start the tool, which set up a local web sever at a high port (eg: 8080), and open any browser to land on the interface.
2. To add a new paper, user have to
   1. upload a pdf file
   2. add bibtex info by
      1. upload a crospending a bibtex file
      2. fill a form to generate bibtex info
   3. add optional tags
   4. add optional note
3. To view paper:
   1. start a search (empty field means any)
   2. a list of reference is returned
   3. (optional) open pdf file
4. To export
   1. start a search
   2. select paper and add to “basket”
   3. go to export folder and get a sorted bib for all and BIB’s for each files and copies of PDF’s

Suggestions are always welcomed :)
