Proposal of a simple and safe method of distributing works (materials) for creative support

Tkler Commons

Tkler Commons (TKCM) is a generic name for projects originating in Japan that provide Tkler Commons Licenses.

TKCM is a new copyright rule for authors of work (material of RPG Maker series "© KADOKAWA CORPORATION" ) to support the creation of copyrighted work. It is a tool for the author to make a statement that "You are free to use my materials as long as you follow these rules." 

There are two kinds of material for RPG Maker series.
One is creator's original material, the other is modified one recorded in RPG Maker.

  • The copyright of the completely original material (original material) is entirely owned by the creator of the material, and terms of use are freely determined by the creator of the material.
  • For the modified material of the contained material (modified material), the RPG MAKER EULA must be adhered to as a key assumption, which is multiplied by that assumption.

TKCM recommends the effects of material distribution based on the following element.

  1. "TKCM certificate" is a simple explanation that allows you to quickly understand the main contents of the license. By referring to the description on this site for the details of the contents, the material creator does not need to describe redundant terms and conditions.
  2. By viewing the "TKCM Certificate" by the material user, it becomes easier to use the material without worrying about difficulties.
  3. It allows you to understand the main contents of the license concisely and prevents misuse of the license.

By using TKCM, the material creator can freely distribute the material while retaining the copyright, and the material user can modify and redistribute it within the license conditions.

The display of these marks are a sign that the material is marked with TKCM.

We recommend that you use MTCM or CC for your own materials.

Modified materials must comply with the RPG MAKER EULA , so MTCM and CC cannot be used.
However, it is a difficult task to determine the conditions clearly and in detail by yourself. It is the role of TKCM to help the material creator in simplifying.

By defining such a template, we are trying to make the sharing of material smoothly.

Conditions setting of TKCM

Under the TKCM-License
The material is available under TKCM license. RPG MAKER EULA must be observed.

Display credit
It is necessary to display the credit of the material creator.

Commercial purposes
Available for commercial purposes.
But do not sell the material itself by RPG MAKER EULA.

Modification
Allow / prohibit modification of the Source material.

Redistribution
Allow/prohibit redistribution of original materials and modified materials. For redistribution, it is necessary to publish on the same TKCM as the source material. As a general condition of TKCM, distribution of works which used materials is not redistribution.

By combining these conditions and considering convenience, TKCM has been reduced to three types.

Material creators will consider how they want to distribute their material and choose the right combination of licenses as needed.

  • Required RPG Maker : ex.RPG Maker MV...
  • Credits: (Describe notational instructions / Material creator name, URL and etc.)

The three combinations are as follows.

There is a link to a page summarizing more detailed description of permission/prohibition for how to display the "TKCM Certificate" banner (or text).
