Goal: Prepare an SLHA-like easy to read and write accord for describing the flow of an LHC analysis.

First proposal made for a generic structure.  CM and MA authors will try to implement a single lepton stop search.

Proposal by Daniel Schmeier & Jamie Tattersall [[2015:groups:tools:lhaad:proposal1]]

Proposal by Nishita Desai, Suchita Kulkarni & Devdatta Majumder [[2015:groups:tools:lhaad:proposal2]]

Combined Proposal by ND, SK, DM, DS & JT: [[2015:groups:tools:lhaad:proposal]]

Combined Proposal from Grenoble 02'16: [[2015:groups:tools:lhaad:proposalGrenoble]]

Proposal to use HEPDATA format for the experiment data section. HEPDATA (https://hepdata.net/) format has recently changed, both old and new formats are text file. New format: https://github.com/HEPData/hepdata-submission (Old format: http://hepdata.cedar.ac.uk/submittingdata , see "simple input file").


Agreements:
  * Binned information should have a simple way to cut it
  * Cuts must not branch but instead can use a common 'predecessor'
  * Syntax must not contain brackets to allow for an easy parsing
  * ...

To Be Discussed Isues:  
  * Format
  * Definition of 'detector constructed' objects like jets, electrons, etc
  * How to enforce documentation of the used objects
  * How to enforce documentation of validation material
  * ...

Suggestion:
  * Acronym: LHADA (Les Houches Analysis Description Accord) and not LHAAD
  * Information about benchmark points
  * Information about process generation needs to be added (merging parameters, generated process, link SLHA file if needed, link to model files etc.)
