In 2020, the founder of JavaMuseum will be celebrating the 20th anniversary of his new media engagement, as well as JavaMuseum is doing. On this occasion, all over the year 2020 a retrospective exhibition will be installed online and offline. Archiving JavaMuseum as a platform for netart, is suffering from the fact, that a large number of netart pieces, but not all, of course, vanished from the net, either they were removed or got an alternative, but unknown new location. In this way, the netart shows at JavaMuseum are partially no more than empty frames. In addition, in 2014 JavaMuseum had been hacked via a security leak. Most of the files had been saved, but some had been deleted. So, the 20th anniversary is representing the occasion to reconstruct the incomplete platforms, and support netart and its historical relevance for new forms in contemporary art, this way.
