Excerpts from Section 3.12 of the Assam Government's state IT Policy says:
(a) The Government would promote use of Free and Open Source Software (FOSS) in all the departments and State agencies, bodies and authorities.
(b) The State Government would promote manpower development and training in use of FOSS, especially in day to day office works.
(c) The State Government would promote imparting training on FOSS in schools and colleges.
(d)Entrepreneurs/ companies using FOSS for application/website development would be given preference over those using third party packaged applications.
(e)All source codes customized/developed for any State Government body shall be duly archived in a repository, and shall be made available freely to other Government departments.
(f) The Government departments and bodies would ensure that Open Document Format (ODF) is adhered to in creating and storing editable documents, data and information and all applications developed by the respective departments adhere to ODF and other Open Standards and are largely independent of Operating Systems (OS) and web browsers.
(g)The Government departments and bodies would ensure that any generic hardware procured has support for multiple Operating Systems(OS) such as Unix, Linux, Opensolaris and other open source platforms.
The policy mandates open standards and ODF, in particular, which has been advocated open source supporters the open standard for office documents (instead of proprietary .doc, OOXML and other data formats). It also extends beyond software and says that all generic hardware purchased by the government should have support for open source software. The section mandating that source code developed for any State Government body shall be duly archived in a repository, indicates that the policy makers also understand the power of the open source development model.
