nestor Handbuch : eine kleine Enzyklopädie der digitalen Langzeitarchivierung

Die Überlieferung des kulturellen Erbes, traditionell eine der Aufgaben von Bibliotheken, Archiven und Museen, ist durch die Einführung digitaler Medien und innovativer Informationstechnologien deutlich anspruchsvoller geworden. In der heutigen Zeit werden zunehmend mehr Informationen (nur) digital erstellt und veröffentlicht. Diese digitalen Informationen, die Güter des Informations- und Wissenszeitalters, sind einerseits wertvolle kulturelle und wissenschaftliche Ressourcen, andererseits sind sie z.B. durch die Kurzlebigkeit vieler Formate sehr vergänglich. Die Datenträger sind ebenso der Alterung unterworfen wie die Datenformate oder die zur Darstellung notwendige Hard- und Software. Um langfristig die Nutzbarkeit der digitalen Güter sicherzustellen, muss schon frühzeitig Vorsorge getroffen werden. Es müssen Strategien zur digitalen Langzeitarchivierung entwickelt und umgesetzt werden. ..

The development of a discovery and control environment for networked audio devices based on a study of current audio control protocols

This dissertation develops a standard device model for networked audio devices and introduces a novel discovery and control environment that uses the developed device model. The proposed standard device model is derived from a study of current audio control protocols. Both the functional capabilities and design principles of audio control protocols are investigated with an emphasis on Open Sound Control, SNMP and IEC-62379, AES64, CopperLan and UPnP. An abstract model of networked audio devices is developed, and the model is implemented in each of the previously mentioned control protocols. This model is also used within a novel discovery and control environment designed around a distributed associative memory termed an object space. This environment challenges the accepted notions of the functionality provided by a control protocol. The study concludes by comparing the salient features of the different control protocols encountered in this study. Different approaches to control protocol design are considered, and several design heuristics for control protocols are proposed

Building information modeling – A game changer for interoperability and a chance for digital preservation of architectural data?

Digital data associated with the architectural design-andconstruction process is an essential resource alongside -and even past- the lifecycle of the construction object it describes. Despite this, digital architectural data remains to be largely neglected in digital preservation research – and vice versa, digital preservation is so far neglected in the design-and-construction process. In the last 5 years, Building Information Modeling (BIM) has seen a growing adoption in the architecture and construction domains, marking a large step towards much needed interoperability. The open standard IFC (Industry Foundation Classes) is one way in which data is exchanged in BIM processes. This paper presents a first digital preservation based look at BIM processes, highlighting the history and adoption of the methods as well as the open file format standard IFC (Industry Foundation Classes) as one way to store and preserve BIM data
