Creative Commons Licenses

Creative Commons Licenses
Open access licenses are a key component of open access (OA) publication models, as they define how shared materials can be used. Creative Commons (CC) licenses are designed to enable creators to flexibly share their works. Here are the basic conditions that may be present in these licenses:

Attribution (BY): You must acknowledge the author of the work in the manner specified by them (e.g., by providing their name and the title of the work).

Non-commercial use (NC): You may use the work only for non-commercial purposes. You cannot use it for profit-making activities.

Share-alike (SA): If you create a derivative work based on the original, you must distribute it under the same license terms. This means that the new work must be licensed under the same conditions.

No derivatives (ND): You cannot create derivative works based on this material. You must use it in its original form without modification.

Here are some main types of licenses:

Creative Commons (CC):
The most popular open licenses that allow authors to specify how their works can be used. There are several variants of these licenses:

• CC0 – Public Domain Dedication: No copyright. This designation indicates that the author has waived their rights and placed their work in the public domain.
• CC BY – Attribution: Allows any use as long as the author is credited.
• CC BY-SA – Attribution-ShareAlike: Allows use and modification, but modified works must be shared under the same license.
• CC BY-NC – Attribution-NonCommercial: Allows use only for non-commercial purposes, with the requirement of attribution.
• CC BY-ND – Attribution-NoDerivatives: Allows copying and distribution, but no changes can be made.
• CC BY-NC-SA – Attribution-NonCommercial-ShareAlike: Allows use only for non-commercial purposes, with the requirement of attribution, and modified works must be shared under the same license.
• CC BY-NC-ND – Attribution-NonCommercial-NoDerivatives: Allows use only for non-commercial purposes, with the requirement of attribution; no derivative works can be created based on this material, meaning it cannot be modified or adapted.

Open Data Commons (ODC):
Licenses aimed at open data that allow for free use and sharing. Examples include the ODC Public Domain Dedication (PDDL) and ODC Attribution (ODC-By), which define the rules for using the data.

These licenses enable creators to maintain control over their works while promoting openness and accessibility of knowledge. The choice of the appropriate license depends on the goals of publication and the intended ways of using the materials.
In accordance with the idea of open access (OA) publishing and the principle of maximizing benefits, it is recommended to provide two licenses when publishing content in open access: CC BY and CC BY-SA.
