11. Juergen Enge 11 media/art/library “The archive is no longer a matter of discrete objects (files, books, art works, etc.) stored and retrieved in specific places (libraries, museums, etc.). Now the archive is also a continuous stream of data, without geography or container, continuously transmitted and therefore without temporal restriction (always available in the here and now).” (Geoffrey Batchen, "The Art of Archiving")

35. Juergen Enge 35 media/art/library Digital Preservation • Long-term, error-free storage of digital information • “long enough to be concerned with the impacts of changing technologies, including support for new media and data formats, or with a changing user community. Long Term may extend indefinitely” (Consultative Committee for Space Data Systems. OAIS, 2002) • Preservation metadata • Preservation metadata stores technical details on the format, structure and use of the digital content, the history of all actions performed on the resource including changes and decisions, the authenticity information such as technical features or custody history, and the responsibilities and rights information applicable to preservation actions (National Library of Australia. Preserving Acces to Digital Information)

52. Juergen Enge 52 media/art/library Arrangement by groups Group Resource

53. Juergen Enge 53 media/art/library Metadata • Core metadata set (fixed) • Extended metadata set (free, depends on object type) • Versioning (no changes to metadata. Only new sets will be attached and old ones will reside on database) • Metadata view depends on object type (label and fields)

54. Juergen Enge 54 media/art/library • Special data type: Date – Every date is an interval – Datestrings are parsed with predefined regular expressions • „Around 1950“ • „17th century“ • „Middle ages“ • „2007-11-04“ • „1973-1977“ – Searching means interval search on two intervals

55. Juergen Enge 55 media/art/library URN / Storage • URN resolves to URL based on – Location – Access protocol – urn:hgkz:design/8:2332/9014/thumb • file:///data/dilps/design/lib01/d/c/120x90_9014.jpg (direct file system access) • http://media3.hgkz.ch/dilps2/resource.php/design/li b01/d/c/120x90_9014.jpg?__SID__ (access via http protocol)

56. Juergen Enge 56 media/art/library Authentication • Domain based authentication model • Every domain uses its own authentication subsystem • Authentication Entities • User (z.B. zhdk/enge) • Group (z.B. zhdk/DDE_ITE.dozierende) • Location (z.B. 192.168.10.12)

57. Juergen Enge 57 media/art/library AAI Integration • The DILPS backend is able to accept users from Switch AAI domain • Granularity of group information sufficient for many cases • Web2.0 Interface doesn‘t allow seemless AAI login (due to redirect) • Excellent possibility for cooperation projects with other institution based on shared media storage • Eventually additional need for group management tool

58. Juergen Enge 58 media/art/library • Access Control Lists are available for all structural elements – Collection – Item – Resource – URN – Group • Rights – Read – Write – Execute – Create – Permission – Revoke Authorisation
