 The inception of CCPN was partly to look at this situation and to develop a more unified approach.It was deemed that multiple, informally connected data standards not only made it more difficult for a user to move from one program to the next, but also adversely affected data fidelity, harvesting and database deposition.To this end CCPN has developed a common data standard for NMR, referred to as the CCPN data model, as well as software routines and libraries that allow access, manipulation and storage of the data.
