What can I do with MetaDB material?

With the CC BY 4.0 license you can:

  • Share — copy and redistribute material in any medium or format.
  • Adapt — modify, transform and build on the supplied material.

This means that when you use it you have to:

  • Give an appropriate credit,providing the name of the creator and attribution parties, a copyright notice, a license notice, a disclaimer notice, and a link to the material.
  • Provide a link to the original CC BY 4.0 license
  • Indicate if you have modified the material and keep the indication of the previous changes.
  • If you change, transform, or develop the material, you must distribute your contributions under the same license as the original (CC BY 4.0). It is not possible to apply legal terms or technological measures that legally prevent others from doing anything the license allows. You can do this in any reasonable way, but not in any way that suggests that MetaDB approve of you or your use.

You also can't:

  • Use licensed material for commercial purposes. Commercial use is primarily intended or directed towards a commercial advantage, payment or monetary compensation, which would constitute a breach of the licence.

The above is an easy-to-read summary of the license, but it does not replace the legal text that is available for reading and downloading on

The license may not provide all necessary permissions for the intended use. For example, other rights such as advertising, privacy, or moral rights may limit how you use the material. You are not obligated to comply with the license for elements of the material in the public domain or where your use is permitted by an applicable exception or limitation.

Appropriate credit if you've been using MetaDB content where you've changed something:
"My blog post/tweet/article" is a derivative of MetaDB used under CC BY 4.0 license"

Examples of commercial and non-commercial use

Creative Commons defines non-commercial use as - "not primarily intended or directed towards a commercial advantage or monetary compensation. For the purposes of this Public License, the exchange of licensed Material with other copyrighted material and Similar Rights by sharing digital files or similar means is Non-Commercial provided that there is no monetary compensation payment in connection with the exchange."

Here are some examples of how to use our opinion about it:

Example #1

I want to use MetaDB material to run a non-profit seminar/training. I want to charge workshop participants a fee to cover the costs of running the workshop.

MetaDB opinion: Non-commercial. You can apply for contributions to cover the direct costs of the workshop services, e.g. rent of the venue, food, drinks, etc., as no "profit" is made. The important thing is that the source is clear: it must be mentioned on each reference to the published data (both on slideshow and verbally), better if with a direct link to the reference web page on MetaDB, and mentioning the type of Creative Commons license used.

Example #2

I want to write a book or article for a magazine where I use MetaDB data or charts even by editing it.

MetaDB Opinion: Commercial. We invite you to contact us to discuss it together.

Example #3

I want to write an article on my blog or on our newspaper regularly registered in the Register of Communication Operators, reporting the data on MetaDB

MetaDB opinion: Non-commercial. Also in the case of use of data on a for-profit newspaper. The important thing is that the source is clear, and that it is mentioned on every reference to the published data, with an attribution link with rel="author" (<a href="" rel="author">link to MetaDB</a>) and a link to the bottom of the article pointing to the MetaDB data license (<a href=" " rel="license">link to MetaDB</a>).

Do you still have doubts?

If you are not sure if your use is classified as non-commercial or falls within the license permissions, please contact us and we will respond to you within 14 business days. In case of alleged commercial use, may suggest a solution, such as deciding on a release on a royalty basis.
