IBM OS/2 Products Licensing Analysis

I took some time to read the IBM DDKs available for OS/2 and try to check which licenses allows the samples to create open source derivate work.

IBM SOMobjects Developer Toolkit V. 3.0
The samples of this Toolkit says:

/* *  * DISCLAIMER OF WARRANTIES. * The following [enclosed] code is sample code created by IBM * Corporation. This sample code is not part of any standard or IBM * product and is provided to you solely for the purpose of assisting * you in the development of your applications. The code is provided * "AS IS". IBM MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT * NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS * FOR A PARTICULAR PURPOSE, REGARDING THE FUNCTION OR PERFORMANCE OF * THIS CODE. IBM shall not be liable for any damages arising out of * your use of the sample code, even if they have been advised of the * possibility of such damages. * * DISTRIBUTION. * This sample code can be freely distributed, copied, altered, and * incorporated into other software, provided that it bears the above * Copyright notice and DISCLAIMER intact. */

This mean that this samples source code can be included on other products and even released under an open source license. But remember to include the "Copyright notice and DISCLAIMER intact".

This source code is available at Github
