Repository Working Group Home Page

This page is the nexus for all the pages that discuss the repository in Chandler — how it's represented, how it's accessed, and how various Chandler elements discover repository changes.

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
• 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
• have to meet the needs of both parcel programmers and end-users.
