Adding content to IMAGINARY

IMAGINARY has as motto "open mathematics", meaning that our content is open to everybody, but also that everybody is invited to contribute with their own content. The IMAGINARY platform allows users to have an account and to upload their content (images, films, software...). This page describes the basics to add your content to IMAGINARY.

License

As a disclaimer, this is not a legal advice, nor substitutes any legal license text. Please make sure that you choose the appropriate license for your interests, maybe with the assistance of a lawyer.

The general rule is that all the content in IMAGINARY must be under open licenses. The main purpose of IMAGINARY is to support and install exhibitions in collaboration with local partners. Hence, it is a fundamental part of its philosophy that the content can be shared at no cost.

The copyright on a work, often marked with the symbol "©" and the phrase "All rights reserved", restricts the copy, distribution and modification of the work to its author and/or rightholders. Open licenses, on the other hand, mean "some rights reserved" and grant some permissions on such activities. For text, images, films, and media in general, the preferred open licenses are Creative Commons. There are different types of CC licenses, which can contain clauses regulating attribution (BY), non-commercial uses (NC), and derivative works (non-derivative (ND) or share-alike (SA)). Please refer to the Creative Commons licenses to know the extent of these clauses. Note for instance that the NC clause prevents other to sell your content for economic profit, but you still can sell your content commercially; or that the ND clause might prevent others to translate your content into another languages.

For software, the CC licenses are discouraged, because software have the two sides source code / executable program. In the Free Software Foundation definition, "free software" must grant four liberties: possibility to run for any purpose, possibility to study the source code, possibility to redistribute, and possibility to change and release modifications. Thus, the term "free" is used as in "freedom", and not in terms of money cost. The term "open source" is not synonym of "free software", and it refers only to the fact that the source code is avaliable for the public, not to the licensing terms. There are several licenses for free/open software (GPL, Apache, FreeBSD...) which differ in several relevant points, most notably the way it spreads the license and the limitations to the "any purpose" condition (as the share-alike and noncommercial clauses). On the other hand, if your software is free of charge (no money cost), but the source code is not available, the software is not free, and it is considered proprietary; sometimes it is called "freeware".

The preferred licenses for IMAGINARY are Creative Commons for media and free/open licenses for programs. Freeware and other models of licenses can be studied individually by the IMAGINARY board. In no way IMAGINARY can be a platform for advertising commercially oriented software or media. In any case, the IMAGINARY board has always the final decision on which content may be part of the platform.

User account

You can create an account and upload contents.

Promotion to Exhibitions

All the content in IMAGINARY is categorized into two sets: "Exhibitions" and "Users". In the Exhibitions category you will find high quality content that we have actually used in physical exhibitions. When you upload some material from your account, it will be automatically assigned to the Users category. No review is done before publication, but we can ask for improvements or delete submissions that do not meet our inclusion criteria. When submitting content to IMAGINARY (always under open licenses), you grant us the permission to spread the content, to use it in exhibitions, and to use it to the extent of the chosen open license. However, we will usually contact you to let you know how your content is used. If we (or any of our partners) use a User content in an exhibition, it will be promoted to the Exhibitions category. Moreover, occasionally we launch calls for participation to renew our exhibitions, as we did in 2013 for Mathematics of Planet Earth, or in 2014 for the ICM NIMS-IMAGINARY exhibition.
