Several activities are collected together as the CEDAR project, with the general theme of providing tools to interlink the other projects, for validation and tuning of the generators, and linking with the users of MC generators. While led from UCL, the project has key people in Glasgow, CERN, Durham, and Fermilab.

The CEDAR teams are responsible for the Rivet (Robust Independent Validation of Experiment & Theory) package, providing generator-independent analysis tools to automatically produce distributions that are comparable to the measured data available from the HEPDATA database. This functions as a critical archive of measurements from previous colliders and is used by all generator projects for tuning and validation of models. It is also in use by the LHC collaborations, and a major goal is to implement key LHC data analyses in Rivet as soon as they become available.

The output from Rivet can be coupled with a mechanism for generator tuning. The Professor package provides an automated tool to do this and tunes provided by it have already been used at the LHC. Rivet is also the central component of the CONTUR project, which uses "Standard Model" measurement analyses from collider experiments to place statistical limits on the viability of New Physics models, before dedicated searches can be performed.

CEDAR also developed and supports the software development platform HepForge. It is active in projects such as the LHAPDF library of parton densities, the HepMC output standard, the Les Houches accords for data exchange between generators, and the LHC Computing Grid "Generator Services" project. CEDAR includes members of the LHC and other experiments, to provide support, liaison and training.
