When the recommended license can not be used

In some cases, it may not be possible to release Harvard Library code under the recommended license. This can happen when the code includes other open source projects that have a more restrictive license that requires projects that incorporate it to inherit the license terms. For example, if a project uses open source code licensed under the LGPL or GPL licenses, there is a requirement that the consuming project also be licensed in the same manner. An example is the FITS project. FITS bundles code released under the LGPL license, and is consequently also released under the LGPL license.

Embedded licenses

If a project includes other licensed code, the main project license.txt file should include a list of the file paths to all of the embedded license.txt files for subprojects within the main project so that a user of the project can know the terms of all embedded code, and hence the overall package. An example is provided below.

Notes on the Apache license

The Apache license is a bit more complete than the simpler MIT license, but it contains a few clauses that are of importance to the Harvard Library. For example, it clarifies that no permission is granted to use the Harvard name:

This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file.

The Apache license also includes a clause that explicitly grants rights to use any patentable content in the code.
