The preservation of science data requires consideration of a wide range of factors from file formats to analysis software. Previous work has reported on the development of Preservation Network Models that capture dependencies at multiple levels and allow reasoning about preservation planning and actions. However this is only one aspect of the development of a trusted preservation environment; there is also a need for quality assurance and relation to explicit policies on data preservation. This paper presents issues of scale for scientific research assets which will be explored further on the SCAPE project. hdl:11353/10.294274 https://phaidra.univie.ac.at/o:294274 application/pdf Conway, Esther Shaon, Arif Matthews, Brian Lambert, Simon CC BY-SA 3.0 AT http://creativecommons.org/licenses/by-sa/3.0/at/ iPRES, Singapore, Digital Preservation, Scientific Data, Preservation Network Models Conferences -- iPRES Conference (001000) -- Conference 2011 (001006) Text eng Managing Preservation Networks: Issues of Scale for Scientific Research Assets: Paper - iPRES 2011 - Singapore
