NeoOffice loads and saves files in the OpenDocument file format, although this can be changed by the user. The OpenDocument file format is an XML file format standardized by OASIS (Organisation for the Advancement of Structured Information Standards). Licensing Sun first released OpenOffice.org under both the LGPL and SISSL, later under only the LGPL, with a requirement for copyright assignment for any contributions to the main code base, which allowed Sun to create proprietary versions of the software (notably StarOffice). NeoOffice chose not to assign its code to Sun, which prevented Sun from using NeoOffice code in official OpenOffice.org versions. There were initially some attempts to resolve the licensing differences and foster more direct cooperation and code-sharing between the NeoOffice and OpenOffice.org developers. However, the NeoOffice developers said that they preferred to work separately from OpenOffice.org because "coordination requires a significant amount of time." The OpenOffice.org developers said that "a proposal to work together has been made, and NeoOffice developers refused". The NeoOffice developers subsequently expressed support for LibreOffice and the launch of The Document Foundation. Though NeoOffice is sold commercially, the source code is still available for free under the terms of the GPL.
