The term “Open Source” comes from a software development movement where free and open source software (FOSS) is defined as software whose source programming is open and available to anyone who wishes to improve, study or modify it, and share the original and the modifications with others. These additional rights are generally granted to the user through a GPL, LGPL, or BSD license. Similarly, the idea of “Open Publication” licenses lets anyone freely see, modify and redistribute the reading/visual content of publications. More often in this expression there are more constraints: Changes or additions must be marked as such, and anyone who releases a modified version must describe where to find the original work. [ENTER] There are a number of reasons and values that have built up a significant global community of “Open” source advocates. Drawing its basic premises into the sphere of education we respect its value of freedom, transparency and collaborative developmental processes. Thus by the term “open source curriculum development” we seek to advance a similarly minded curriculum development methodology. [ENTER] To date all key publications of SOUL have been published within this ethos. We seek to provide both paper and digital resources as freely as possible. As in the case of this guide you may be reading a digital version that we have given full permission for Ones to study, share, modify and improve with the request that this original publication be clearly referenced. We are committed to the principle that where resources are produced in a way that requires a charge to the intended end user we will strive to develop a parallel way for the content to be accessed as freely as possible. Collectively we must find and value ways that stop monetary issues being a fundamental block to the process of education and creativity. [ENTER] Naturally as a charitable organisation uCA require (from those who can) incoming donations, contributions, investment, funds and all other forms of wealth to sustain this policy.
