Storing, securing and making born-digital or digitised information available in a sustainable manner is a major challenge. Concepts such as metadata, Meta Information, Open Data, Big Data… are on the rise but their meaning and content - let alone their implications for social impact - is only seldom questioned. The Working Group Sustainable Publishing of (Meta)data therefore aims to organise a workshop with the central theme “(meta)data and archival science”. This workshop will take place on 14 and 15 May 2018 at the National Archives of Belgium in Brussels.
