(English version) These are the copyright rules of the LVI2023 conference. Author assures that he has all copyright use rights on his/her work; no other rights exists. Author is obliged to inform the publisher of risks of violation of personality rights. Author grants and assigns to the main editor Prof. Dr. Dr. Erich Schweighofer the exclusive, permanent, world-wide, transferable, sub-licensable and unlimited user rights (e.g. to reproduce, publish, distribute, transmit, make available etc.). No remuneration is paid to the author. A copy of the proceedings (PDF, if available in print) will be given to authors as remuneration. The author can publish their work on their own commercial website. After the commercial window (e.g. 2 years, very often earlier, at the discretion of Prof. Dr. Dr. Schweighofer), a Gold Open Access policy will be applied. The final published version of your article is permanently and freely available online for anyone, anywhere to read. The “commercial window” is the compensation for the otherwise usual article publication charge. You can then: share your research with everybody, keep your copyright for post-publication, publish under a license with few or no restrictions for re-use of the work. In all cases, credit must be given to the original publication in the IRIS proceedings. Licenses agreed by Prof. Dr. Dr. Schweighofer remain valid but loose the exclusivity.
