The concept of digital sustainability introduces a holistic approach on how to maximize the benefits of digital resources for our society. The nine basic conditions for digital sustainability also provide a contribution to potential solutions to the challenges of digital preservation. Elaborateness, transparent structures, semantic data, distributed location, an open licensing regime, shared tacit knowledge, participatory culture, good governance, and diversified funding support the long-term availability of digital knowledge. Therefore, in this conceptual paper, we explain the links between digital sustainability and digital preservation in order to increase the impact of both. We conclude by presenting the political agenda of the Swiss parliamentary group for digital sustainability.

In 2015 the national Network for Digital Heritage was established. This network is based on three pillars: to make the digital heritage wider visible, better usable and more sustainable preserved. A series of collaborative projects are in progress since Summer 2015, framed within three working programs, all with their own but integrated set of dedicated actions in order to create a national infrastructure in the Netherlands, based on an optimal use of existing facilities. In this paper the focus is on the activities related to the sustainable preservation of the Dutch national digital heritage. What are the developments and where are we now, with the program running for a year and the first results are delivered.
