About Files
It is an Eclipse Foundation requirement that the About file (about.html) exist and be accurate for every plug-in, whether it contains third party code or not. If a plug-in uses or implements encryption this must also be called out in the About file. Recently I have noticed that many abouts that contain third party code are not an accurate reflection of the content redistributed in that plug-in or worse, the about file is missing! There are 2 basic about templates:
- about for plug-ins that contain ONLY EPL CONTENT
- about for plug-ins that contain some or all NON-EPL CONTENT - sometimes we refer to this as third party content
The platform also uses an ABOUT file for SOURCE PLUG-INS.
The Lucene plug-in demonstrates a simple example of an about that contains third party content. Notice the link to license files in a directory called about_files. The Europa projects tend to do this by convention so the about file isn't too long.
POINTS TO REMEMBER:
- Nested third party code must be identified in the about and all licenses applicable to all third party content in the plug-in should be linked from or present in the about.html file. See the about in the Tomcat plug-in for an example of this (MX4J is nested).
- Encryption (either use of or implementation of) should be identified in the about. See the about for the Authorization Compatibility plug-in for an example of this.
Note: this is not an official Eclipse Foundation legal document. It was written as a abbreviated guide for plug-in developers writing Abouts. For the official Eclipse documentation see the guide to the legal documentation for Eclipse based content.
