Repository Working Group Home Page

This page is the nexus for all the pages that talk about the repository in Chandler -- how it's represented, how it's accessed, and how various Chandler elements find out when it changes.

The Repository Working Group meets weekly at 3pm on Tuesdays

Project Goals

We want Chandler to be good at handling both structured and un-structured data. Chandler's data handling framework should be less rigid than say a relational database, but allow the user to add more structure than is possible with a spreadsheet or a word processor. The data framework will need to handle both structured and un-structured data, and it will have to meet the needs of both parcel programmers and end-users.
