Gracenote's technical staff has developed many great technologies, products, and services over the years. Much of this is embodied in software that has, up to now, been considered proprietary to the company. However, there is a lot of Gracenote software that has broad utility for the software community at large, and need not be kept closed. Gracenote has created an open source program in an effort to provide a means for such software to be made available to the community, with few terms and conditions in the hope that such software will find broad acceptance. All software released as open source has been utilized in Gracenote products or services and is believed to be of high quality and utility.
Each item offered as part of the Gracenote open source program is championed by the engineers who would like to see their code used by others in as many programs or products as possible. On their own initiative, engineers polish their work and guide it through the process Gracenote has established to ensure that only excellent software is published as open source works. Authors are given full credit, and may also post the software for distribution on other sites and forums at their discretion. Questions, enhancements, or bugs are reported to the author, who may respond as they see fit.
The Gracenote Open Source License (GOSL) v1.0 is a short, simple, nonburdensome license that is intended to foster the adoption of source code released by Gracenote. It is a nonviral license that allows you to use Gracenote source code any way you like, without restriction, so long as you include the license document in any product that includes Gracenote source code. There are other important points to be aware of, but this is the key feature of the license. Please read the license text carefully before using Gracenote open source products.
The license is included in all open source packages released by Gracenote. It can also be found at the following link: Open Source License
