is fully hyperlinked with the permanent DOIs that will take you to the public documents in question. Likewise, the DIRAC DFC LFNs for non-public files are listed there too. Instructions for getting files out of the DFC are, of course, available on the UserGuide [0]. Secure access is trivial with an SL6 command line with access to CVMFS (for example, on the RAL tier-1 cluster) and your Grid certificate installed in ~/.globus - for example, to get the GridPP Dissemination Handbook: Addendum simply use:

$ source /cvmfs/ganga.cern.ch/dirac_ui/bashrc

$ dirax-proxy-init -g gridpp_user -M

$ dirac-dms-get-file /gridpp/ENG/004/v1-0/diss-handbook-add.pdf

Instructions for contributing to these documents can be found in the GridPP Dissemination Handbook: Addendum - GridPP-ENG-004 - which you will have just downloaded. In short, you need a GitHub account and to join the GridPP GitHub Organization [1] which will give you access to the private repositories hosted therein; from there you can fork, branch and pull request the documents as required.  (As it happens, the case studies document is actually a public repository [2], and code used to generate the v1.0 release has been assigned its own DOI [3]. You can read more about how to assign citable, permanent DOIs to code here [4]).

Cheers, Tom
