OpenVista
Introduction
Medsphere is a company initially established by physicians to provide an open-source version of the public-domain VistA platform. Due to early management and organizational problems, a proprietary version was developed instead, and a significant backlash developed against the company.
Medsphere soon realized that without the co-operation of the VistA community at large and a return to the values of the open source community, its support was in jeopardy.
It has therefore again started to develop an open-source version of VistA called OpenVistA.
While Medsphere has integrated the proprietary Cache version of the MUMPS database in its enterprise version, it has also recently package the open source GT.M version of MUMPS into a new version, similar to WorldVistA.
