(Openbravo ERP is distributed under the Openbravo Public License, a free software license based on the Mozilla Public License (MPL) Most ERP's are customized and adapted for end-user implementation. This means that, as at Openbravo we don't directly carry out client installations except locally, most of our direct users will be intermediaries - Independent Software Vendors or Value Added Resellers - who will be using Openbravo for creating enhanced adapted solutions to their client's needs. Use of a strong copyleft license such as the GPL would force these intermediaries to distribute their solutions under the same copyleft license - something they may not wish to do or force them into a new business model which they have not considered yet. At Openbravo, we want to let both open source and commercial developers to use the Openbravo ERP core. We have therefore chosen the MPL as the basis for our license because it makes the ERP code available for extension, customization and integration with proprietary software and gives intermediate distributors and integrators the freedom to choose their licensing model. On the other hand, it keeps the source code for the core package freely available for us and the open source community to build on, providing access, copying, modification and free distribution rights. Therefore there are a number of reasons for choosing the MPL as a basis for our license. In addition to balancing the commercial purpose set out above with the reciprocity obligations on the core code, the MPL is recognised and accepted with the Open Source community, and it is suitable for software that includes other open source technologies licensed under various non-copyleft licenses (Apache Software License, LGPL, etc.).
