The Open Content License [4] is a share-alike public copyright license by Open Content Project in 1998. [1] The license can be applied to a work to make it open content. It is one of the earliest non-software free content licenses.

History and reception

The Open Content License, dated July 14, 1998, predates the GNU Free Documentation License (GFDL) and other non-software public licenses. Though discussions were held between David A. Wiley, creator of the Open Content License, and Richard Stallman, leader of the Free Software Foundation, who created the GNU General Public License for software and would create the GFDL. [5] The license text is titled "OpenContent License (OPL)". [6] "OPL" stood for OpenContent Principles and License. [7]

This license is not compatible with most other licenses (beside permissive licenses) in that it requires derivative works to be licensed under the Open Content License (Viral license). With the exception of media and handling costs, it forbids charging for copies of a licensed work, but does not otherwise forbid commercial use. [8]

Another license released a year later, also by the Open Content Project, is called the Open Publication License. The OpenContent as well as the Open Publication license were succeeded by the Creative Commons licenses in 2003. [9] [1]

A project licensed under the OPL is Open Icecat, which was launched in 2005 as a global open catalogue for e-commerce, and is embraced by the tech sector.

The Open Publication License (OPL) was published by the Open Content Project in 1999 as a public copyright license for documents. It superseded the Open Content License, which was published by the Open Content Project in 1998. Starting around 2002–2003, it began to be superseded, in turn, by the Creative Commons licenses.

<span class="mw-page-title-main">Creative Commons license</span> Copyright license for free use of a work

A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted "work". A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.

The Free Art License (FAL) is a copyleft license that grants the right to freely copy, distribute, and transform creative works except for computer hardware and software, including for commercial use.

Open gaming is a movement within the tabletop role-playing game (RPG) industry with superficial similarities to the open source software movement. The key aspect is that copyright holders license their works under public copyright licenses that permit others to make copies or create derivative works of the game.

<span class="mw-page-title-main">Share-alike</span> Condition in some free copyright licenses

Share-alike (🄎) is a copyright licensing term, originally used by the Creative Commons project, to describe works or licenses that require copies or adaptations of the work to be released under the same or similar license as the original. Copyleft licenses are free content or free software licenses with a share-alike condition.

This comparison only covers software licenses which have a linked Wikipedia article for details and which are approved by at least one of the following expert groups: the Free Software Foundation, the Open Source Initiative, the Debian Project and the Fedora Project. For a list of licenses not specifically intended for software, see List of free-content licences.

License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program. Proprietary licenses are generally program-specific and incompatible; authors must negotiate to combine code. Copyleft licenses are commonly deliberately incompatible with proprietary licenses, in order to prevent copyleft software from being re-licensed under a proprietary license, turning it into proprietary software. Many copyleft licenses explicitly allow relicensing under some other copyleft licenses. Permissive licenses are compatible with everything, including proprietary licenses; there is thus no guarantee that all derived works will remain under a permissive license.

Free video is video content that is free to use for any purpose, or licensed under a free and open license to such an effect, at least for distribution, and at most for modification and commercial usage. This can also apply to graphical animations.

<span class="mw-page-title-main">Free content</span> Nonrestrictive creative work

Free content, libre content, libre information, or free information is any kind of creative work, such as a work of art, a book, a software program, or any other creative content unrestricted by copyright and other legal limitations on use. These are works or expressions which can be freely studied, applied, copied and/or modified, by anyone, for any purpose, including, in some cases, commercial purposes. Free content encompasses all works in the public domain and also those copyrighted works whose licenses honor and uphold the definition of free cultural work.

<span class="mw-page-title-main">Free-software license</span> License allowing software modification and redistribution

A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a license is free software as conferred by the copyright holder. Free-software licenses are applied to software in source code and also binary object-code form, as the copyright law recognizes both forms.

<span class="mw-page-title-main">Copyleft</span> Practice of mandating free use in all derivatives of a work

Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, freedoms refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, and scientific discoveries, and similar approaches have even been applied to certain patents.

<span class="mw-page-title-main">GNU General Public License</span> Series of free software licenses

The GNU General Public License is a series of widely used free software licenses, or copyleft, that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely-used permissive software licenses such as BSD, MIT, and Apache.

<span class="mw-page-title-main">GNU Free Documentation License</span> Copyleft license primarily for free software documentation

The GNU Free Documentation License is a copyleft license for free documentation, designed by the Free Software Foundation (FSF) for the GNU Project. It is similar to the GNU General Public License, giving readers the rights to copy, redistribute, and modify a work and requires all copies and derivatives to be available under the same license. Copies may also be sold commercially, but, if produced in larger quantities, the original document or source code must be made available to the work's recipient.

Creative Commons is maintaining a content directory wiki of organizations and projects using Creative Commons licenses. On its website CC also provides case studies of projects using CC licenses across the world. CC licensed content can also be accessed through a number of content directories and search engines.

A Rights Expression Language or REL is a machine-processable language used to express intellectual property rights and other terms and conditions for use over content. RELs can be used as standalone expressions or within a DRM system.

<span class="mw-page-title-main">Definition of Free Cultural Works</span> Project to define free content

The Definition of Free Cultural Works evaluates and recommends compatible free content licenses.

A free license or open license is a license that allows copyrighted work to be reused, modified, and redistributed. These uses are normally prohibited by copyright, patent or other Intellectual property (IP) laws. The term broadly covers free content licenses and open-source licenses, also known as free software licenses.

A public license or public copyright license is a license by which a copyright holder as licensor can grant additional copyright permissions to any and all persons in the general public as licensees. By applying a public license to a work, provided that the licensees obey the terms and conditions of the license, copyright holders give permission for others to copy or change their work in ways that would otherwise infringe copyright law.

Software relicensing is applied in open-source software development when software licenses of software modules are incompatible and are required to be compatible for a greater combined work. Licenses applied to software as copyrightable works, in source code as binary form, can contain contradictory clauses. These requirements can make it impossible to combine source code or content of several software works to create a new combined one.

[The] Open Content License (July 14, 1998), which was replaced by the Open Publication License (June 8, 1999), were the first licenses to bring the ideals of open source software to the world of content. The OCL predates the GFDL (Nov 2002) and Creative Commons (Dec 2002) by over four years, while the improved OPL predates both by over three years. The OCL was developed primarily by me... The improved OPL was written primarily by Eric Raymond after discussions with me, Tim O'Reilly, and others... The OPL was truly innovative in that, in addition to requiring citation of the original author as source, it contained two license options which authors could choose to invoke: one restricts users' abilities to creative derivative works, while the second restricts users' abilities to make certain commercial uses of the material. The student of open content licensing will recognize that these are exactly the options that Creative Commons now employs. What may be forgotten is that in version 1.0 of the Creative Commons licenses, Attribution was actually included in the licenses only as an option. In version 2.0 of the CC licenses (May 24, 2004) attribution was standard on every license, and there were two licenses options: one regarding derivative works, and one regarding commercial use. So in terms of high level structure, the OPL was here about five years before CC. ... Actually, the [OCL and OPL] licenses weren't that great, seeing as I am not a lawyer, and neither was anyone else involved in the creation of the license. The concept was right, and the execution was "good enough," but Creative Commons (with its excellent lawyers and law school students) created a better legal instrument. As I said on the opencontent.org homepage on Monday June 30, 2003: 'My main goal in beginning OpenContent back in the Spring of 1998 was to evangelize a way of thinking about sharing materials, especially those that are useful for supporting education. ... I'm closing OpenContent because I think Creative Commons is doing a better job of providing licensing options which will stand up in court [and I'm joining] Creative Commons as Director of Educational Licenses. Now I can focus in on facilitating the kind of sharing most interesting to me ... with the pro bono support of really good IP lawyers... The OpenContent License and Open Publication License will remain online for archival purposes in their current locations. However, no future development will occur on the licenses themselves.' ... Anyone interested in a license like this is far better off using a Creative Commons license.
