The TÁRKI Open Access Platform (TopAp) aims to provide open access to the TÁRKI research results online, without access fees or other barriers. We manage our research data responsibly in accordance with the FAIR principles of "discoverability", "accessibility", "interoperability" and "reusability". We follow the very reasonable principle of being "as open as necessary". Therefore TÁRK launched its very own open access platform to provide opportunity for a broader audience to immerse into TÁRKI's publications.
