This license is based on the Extend-NMR license, that in turn was put together from the licenses of the individual programs. A major change is that I have removed the requirement of having name and contact details of the user's Lab head. I have also reworded the license so that it does not assume that it is being clicked/signed on download.  We could change that, but it would mean changing our download procedures.  It might be easier to incorporate the license in each source code file, either directly or as a link. 

CCPN License - DRAFT

Definitions:

• CCPN Software: Software authored by CCPN and covered by this license.

• Workplace: The laboratory, group, or work unit where CCPN software is used.

• Organisation: The legal entity that includes the Workplace or that profits from the use of the CCPN software.
  

• CCPN member: A person that has signed up for CCPN membership and that currently fulfills the conditions for membership.
  

License:

In using or acquiring CCPN software each person implicitly accepts the following requirements and conditions:

   1. The person acquiring or using this software is authorized by his Workplace and Organisation to commit to this agreement, which is binding on this person, this person's Workplace, Organisation, and all other persons and institutions with whom this software is shared.

   2. This agreement covers all CCPN software in any form, including source or binary code, programs or program fragments, updates, patches, bug fixes, and additions. The provisions in this license do not, however, apply to software that is explicitly distributed under a different license, such as the GNU LGPL license, provided that the alternative license is clearly reflected in the individual files that it covers.

   3. Only members of CCPN are allowed to acquire CCPN software except as detailed under point 6).
  
   4. In order to become a CCPN member it is necessary to register; registration can be found at the CCPN web site http://www.ccpn.ac.uk. CCPN membership will cease to be valid if the records of contact details and current Workplace are not kept current by the member. 

   5. CCPN may charge a fee for CCPN membership. Currently membership is free, except for individuals working for a for-profit Organisation. It is a condition of membership that all applicable fees have been paid.
  
   6. CCPN software, once acquired, may be shared with others working in the same Workplace as the original acquirer.

   7. Except as stated in 6) CCPN software, whether in whole or in part, modified or unmodified, may not be redistributed in any way, except within the current Workplace of a current CCPN member.
  
   8. A Workplace that has legally acquired CCPN software, but that no longer contains a current member of CCPN, may continue to use the software, and may modify it for internal use, but may not acquire new software or distribute the CCPN software to others.
  
   9. CCPN software provided 'as is' and is without warranties, expressed or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose or a warranty of non-infringement. The authors will not be held liable for any use you make of the software.
