Haiku implementation of the BeOS API. Non-BeOS implementations The majority of the Be API has been reimplemented by Haiku for their open-source BeOS replacement, although in an effort to catch up with the intervening years since BeOS R5 some additional functionality has been added, ranging from large changes to the Mail kit to support IMAP, encrypted connections and multiple accounts, and a move to OpenGL 1.5 support via Mesa 3D. Alternative systems have attempted to draw some inspiration (Syllable) from the BeOS API, but are not making attempts to provide a base to port applications. A private port of much of the API to Microsoft Windows and later Linux (using GTK+) was done by Gobe Software to enable them to port their Gobe Productive office suite to these platforms from BeOS, where it had originally been developed. Documentation The entire API, as it was at the stage of BeOS Revision 3, was documented in two paper books - the Be Developer Guide and Be Advanced Topics, released by O'Reilly Media under a Be, Inc imprint in 1997/8. In addition, a digital representation of this was provided and updated with BeOS itself. In 2007, ACCESS Co Ltd, the owners of Be, Inc's intellectual property, released the text of this under a Creative Commons licence.
