However, it is more common for a CLA to have a copyright license that allows the author of the contribution to retain ownership of the copyright, which may be more desirable from the contributor`s point of view. The copyright license in the CLA cannot be more restrictive than the open source license used to distribute the project code. For example, if the open source project distributes its code under an “authorized” copyright license, for example. B the MIT or BSD license, its CLA cannot request software contributions under a more restrictive license, like. B a “copyleft” GPL license. This would impose additional restrictions that would exclude distribution under the permissive licence of the project and undermine the original intent of the permissive licence. Mbed OS is an open source software ecosystem for the Internet of Things. Contributions are an important part of the ecosystem, and our goal is to make it as easy as possible to become a contributor. The next major change with Mbed TLS 3.0 will be the switch to a single open source license. Mbed TLS 2 was distributed under a GPL/Apache 2.0 license, which confused only partners and contributors. The move to Apache-2.0-only allows us to accept community contributions on an incoming release basis, without anyone needing to sign a Contributor (CLA) law licensing agreement, making the process easier for everyone. Applications for the Mbed platform can be developed with Mbed Online FDI, a free online code editor and compiler. Only a web browser should be installed on the local PC, because a project is compiled in the cloud, i.e.
on a remote server, with the ARMCC C/C compiler. IDE mbed offers the ability to import, export and share code with distributed mercurial version control and can also be used for generating code documents. Applications can also be developed with other development environments such as Keil-Vision, IAR Embedded Workbench and Eclipse with ON-board ARM GCC tools. Another advantage of using a CLA is that it offers a formal mechanism for the open source project to track its contributors and contributions. Each contributor can provide in the CTC identifying information that allows the project manager to keep an overview of the major contributors to the project where they are employed, as well as other statistical information on contributions to the project. As we have seen above, a CLA is essentially a legal contract that can be adapted for a specific open source project. While the CTC may define certain rights and obligations for a contributor based on its contribution to an open source project, it may also contain restrictions on how the project itself can concede and distribute the contribution.
