The questions below provide a direct way into the information on this website. They are grouped here to make them easier to browse, but the groups are an index rather than a hierarchy in which the knowledge resources are contained.
Choose the question that comes closest to what you are trying to understand, investigate or do. The wording of each question is kept identical wherever that knowledge resource is referenced.
A website does not stand alone. Content, files, software, domain registration, DNS, email, hosting and account access together determine whether information remains reachable, transferable and manageable.
Public information is collected and redisplayed by search engines, business directories, maps, archives and other systems. As a result, findability, outdated data and incorrect interpretations can become problems in their own right.
Responsible data management starts by making visible what information exists, where it is stored, who can access it and which rules or agreements are relevant. This applies both to public personal data and to data inside organisations and online systems.
Information takes a visual and sometimes physical form. Identity, colour, file formats, print, material and medium together determine how information becomes recognisable, readable and usable.
Digital files and purchases remain usable only when access, licences, storage, file formats and dependencies on services are understood as well. Preservation therefore means more than simply keeping a copy somewhere.
