The appeal of open source is that anyone has the right to copy, modify, and redistribute the software, subject to the terms and conditions of the applicable open source license (such as MPL, GPL, and so on). While we at Dimdim do indeed make our software available to the world as open source, please understand that we are not thereby providing third parties with the right to use the Dimdim trademarks in inappropriate ways. Nor are we in any way relinquishing our copyright ownership of any of Dimdim software.
Dimdim Trademarks
"Dimdim" and the Dimdim logo are trademarks of Dimdim, Inc. and are protected under the laws of the United States and other countries. The Dimdim trademarks identify our company as the source and origin of Dimdim products that we distribute under an open source license. Other companies are not allowed to distribute their own products - even products derived from Dimdim software under our open source license - under the Dimdim trademarks.
In order to preserve their value as trademarks, Dimdim, Inc. prohibits inappropriate uses of these Dimdim trademarks by other companies, organizations or individuals.
Some trademark uses, of course, are legitimate, such as to properly indicate Dimdim, Inc. software or related services. Wherever you do use the Dimdim trademark to properly indicate Dimdim, Inc. software or related services, you must include the following notice wherever your own trademarks are noticed:
"Dimdim" and the Dimdim logo are trademarks of Dimdim, Inc.
Your ability to produce and redistribute derivative works of or collective works that include Dimdim software is governed by the open source license under which you received it (unless you enter into a formal agreement with Dimdim, Inc. under which you receive alternative licensing terms). Open source licenses do not include a license to trademarks, and so for you to produce a derivative work of or a collective work including the Dimdim software for distribution consistent with trademark law, you must remove all occurrences of the Dimdim trademark and the Dimdim logo that are visible to users so that nobody can be confused that Dimdim, Inc. is the source or origin of your derivative or collective works.
Moreover, none of the Dimdim trademarks can be used in the promotion, identification, or distribution of
* A derivative work of Dimdim software;
* A collective work that includes the Dimdim software; or
* Independent software that offers similar function to that embodied within Dimdim software
unless you have received written permission to do so from Dimdim, Inc. To do otherwise would inevitably confuse people about the source or origin of those other works or incorrectly imply that Dimdim, Inc. endorsed them.
Dimdim Copyright
The copyright in and to the Dimdim Collaboration Suite is owned by Dimdim, Inc. An appropriate copyright notice is carried within each source file of Dimdim Software, and also on the login screens of the user interface:
Portions © Copyright 2006 Dimdim, Inc.
These Dimdim copyright notices should not be confused with trademarks described earlier. Dimdim copyright notices (and any copyright notices of our contributors that we have placed in Dimdim software) must remain unmodified so that users of derivative or collective works created from Dimdim software always know that Dimdim, Inc. (or, in some cases, our contributor) owns a copyright in the original work.
The Dimdim-owned portions of any collective or derivative works remain available under our open source license. Furthermore, those collective and derivative works are subject to the reciprocity provisions of our license, as described in the Dimdim Licensing FAQ, which may also make them available under the same open source license. For these reasons, we require that you leave our copyright notices wherever they appear in your derivative works of or collective works including the Dimdim Collaboration Suite, and to display our copyright notice in the same places and with the same prominence as you display your own copyright notice.
It is generally considered good open source practice to identify in the source code of your derivative or collective works your own copyright notices for the portions of the work you added or changed. We suggest that you also include a change log of the alterations that you have made in order to help downstream users or redistributors identify and distinguish what you have created from what Dimdim, Inc. has created and made available as open source software.
Again, unless you have entered into another formal agreement with Dimdim, Inc. under which you have received alternative licensing terms, your ability to produce and redistribute derivative works of or collective works that include the Dimdim Collaboration Suite is governed by the open source license under which you received it and by laws relating to copyrights and trademarks described in this Policy.
