engine. OpenRPT is an LGPL licensed open source project also administered by xTuple and hosted on GitHub. The web client is written entirely in JavaScript using Enyo to manage the presentation layer and Backbone for the model layer. It communicates with a NodeJS server which provides the REST web services interface. The web client uses Pentaho to provide reporting and business intelligence functions. Extendability One of the major advantages of the PostBooks (and commercial) software is the technology it is written in, which allows significant customization of the database and functionality of the system. Customization is overlaid over core functionality and allows easy manipulation of the system from the simple addition of an extra field, to significant functionality overhauls. This is evident in that the entire Manufacturing feature set is developed as a scripted package over the commercial core application. As such PostBooks can be modified to meet the requirements of most organizations. Community Before going proprietary, PostBooks had a mature and established community. While the project was technically maintained on GitHub, most community activity is initiated at the xTuple hosted community website where additional forums and technical documents are available. PostBooks is written using English as the base language but has been or is being translated into several languages by the community at large including Spanish, French, German, Russian, Turkish, Chinese and Portuguese.
