The Web is increasingly becoming a platform for linked data. This means making connections and adding value to data on the Web. As more data becomes openly available and more people are able to use the data, it becomes more powerful. An example is file format registries and the evaluation of format risks. Here the requirement for information is now greater(More)
An accepted digital preservation workflow is emerging in which file formats are identified and those believed to be at risk are migrated to what are perceived to be less risky formats. This raises important questions about what to convert and when, if at all. In other words, how to connect file identification and migration. This area has become known as(More)
The move to digital is being accompanied by a huge rise in volumes of (born-digital) content and data. As a result the curation lifecycle has to be redrawn. Processes such as selection and evaluation for preservation have to be driven by automation. Manual processes will not scale, and the traditional signifiers and selection criteria in older formats, such(More)
The OPTIMIX project will focus on studying innovative solutions enabling enhanced video streaming in an IP based wireless heterogeneous system, based on cross layer adaptation of the whole transmiss ion chain.\nTo achieve this goal, it is proposed to develop a scheme including all e lements of major importance in a point to multi point video streaming(More)
Relative to the current Master/Slave computing model cloud storage file systems, including GFS, HDFS, Sector, we proposed a general model of Peer-to-Peer based Cloud Storage file system, and constructed a prototype system named MingCloud based on Kademlia algorithm. Focused on redundant strategy selection and design of the storage system, our experiment(More)
In the beginning, SPAR, the National Library of France's repository, was designed as the OAIS softwarified. It was intended to be a "full OAIS", covering all preservation needs in one tidy system. Then as its potential revealed itself across the library, high hopes arose for a do-it-all digital curation tool. Yet in day to day preservation activities of the(More)
Bibliographic metadata plays a key role in scientific literature, not only to summarise and establish the facts of the publication record, but also to track citations between publications and hence to establish the impact of individual articles within the literature. Commercial secondary publishers have typically taken on the role of rekeying, mining and(More)
