The Kanga Home Page

Introduction

Kanga is an ancronym for "Kind ANd Gentle Analysis" (Roo is the TLA for Kanga packages). Kanga was developed in response to recommendations from the August 1999 computing review :
  • organize an effort to provide a limited-function, short-to-medium term solution for micro analysis using standard framework, but without Objectivity
  • this approach should be considered as a near-term solution for distributing data to small groups
  • develop strategies for physics analysis in case Objectivity cannot achieve design goals
In the Computing Review 2002 KanGA was found to be "the de-facto format for physics analysis at Tier-C sites and is used by approximately half the analyses at SLAC". "KanGA should be given the appropriate resources for continuing development and support". On the other side "... it may be prudent to not attempt to broaden the use of Objectivity within BaBar and possibly to try to reduce it in a future Computing Model".
