"Digital Long-Term Preservation – A Provenance Story"


Abstract: Nowadays, the need for digital long-term preservation is growing. A lot of the digital information produced merely a decade ago is in danger of getting lost as technologies are changing. This also threatens a lot of information from heritage institutions in Belgium. Analogue carriers are degrading and digitisation is a must, but digital copies are also subjected to many risks, e.g., data carrier corruption, or file formats becoming obsolete. For this, a distributed long-term preservation platform is being developed overcoming those risks, assuring the accessibility of the information. This distributed archive harvests the data records from the institutions, disseminates the data as Linked Open Data, and archives the data for the long-term by providing and tracking its provenance information. This provenance information is described using PREMIS OWL, our developed and (LOC) approved semantic implementation of the PREMIS 2.0 data dictionary.


Sam Coppens is a researcher and Ph.D. candidate in computer science and engineering at the Multimedia Lab of Ghent. He received his M.Sc. degree in Engineering (specialisation on micro-electronics) from K.U. Leuven, Belgium, in 2005. As a researcher he is involved in several projects with the emphasis on semantic web technologies and cultural heritage. His research interests and major expertise is centered around metadata/ontology modeling, semantic web technologies (a.o. linked open data), archiving and aggregation/harvesting (a.o. in the context of Europeana). He is member of the W3C’s provenance incubator group, IASA metadata and documenting committee, SWPM programme committee and involved in several standardization activities, e.g., PREMIS.


Erik Mannens received his M.Sc. degree in Electro-Mechanical Engineering (1992) at KAHO Ghent and his M.Sc. degree in Computer Science (1995) at K.U.Leuven University. Before joining IBBT-MMLab in 2005 as project manager, he was a software engineering consultant and Java architect for over a decade. His major expertise is centered around metadata modeling, semantic Web technologies, broadcasting workflows, iDTV and Web development in general. He is involved in several projects as senior researcher and is finishing up his PhD on Semantic News Production. He is co-chair of W3C's Media Fragments Working Group and actively participating in other W3C's semantic Web standardization activities. On all of these subjects he has published several papers and book chapters. He is also an active member of the technical committees of ACM MultiMedia, IEEE CCNC, SAMT and MAReSO.
