Bad/broken link to "licesenses" in CCLA document about fmi-standard.org

What should be the content of this page?

[chrbertsch]

We could make it point to https://fmi-standard.org/about/

This contains all kind of of license and CCLA information:

• "The FMI specifications are published under the CC-BY-SA 4.0 (Creative Common Attribution-ShareAlike 4.0 International) license. Source code, such as C-header and XML-schema files, that accompany the specification documents, are provided under the 2-Clause BSD License."

• "All contributors have to sign the Corporate Contributor License Agreement (CCLA). Therefore, the first step is getting your company to agree and sign the CCLA. The CCLA ensures that all IP contributed to the FMI standard will be licensed to the Modelica Association (MA) which in turn will sublicense the FMI standard to tool vendors implementing it and end users using it, free of charge."

We should change the 2nd sentence to

• "All contributors have to sign the Corporate Contributor License Agreement (CCLA) (or equivalently must be corporate contributors that have signed the CLA of the Modelica Association). Therefore, the first step is getting your company to agree and sign the CCLA/CLA. This ensures that all IP contributed to the FMI standard will be licensed to the Modelica Association (MA) which in turn will sublicense the FMI standard to tool vendors implementing it and end users using it, free of charge."
