The scientific and information communities have largely mastered the presentation of, and linkages between, text-based electronic information by assigning persistent identifiers to give scientific literature unique identities and accessibility. Knowledge, as published through scientific literature, is often the last step in a process originating from(More)
The 'Berlin Declaration' was published in 2003 as a guideline to policy makers to promote the Internet as a functional instrument for a global scientific knowledge base. Because knowledge is derived from data, the principles of the 'Berlin Declaration' should apply to data as well. Today, access to scientific data is hampered by structural deficits in the(More)
The World Wide Web has not only revolutionized the area of traditional hypermedia, it is also starting to influence adaptive hyper-media research. The main feature of the World Wide Web has been simplicity, standards based protocols and formats, and open environments and systems. In this paper we will investigate the potential of these aspects for adaptive(More)
Learning Objects Metadata describing educational resources in order to allow better reusability and retrieval. Unfortunately , annotating complete courses thoroughly with LOM metadata can be a tedious task. In this paper we show how additional inference rules can make this task easier, and allows us to derive additional metadata from existing ones.(More)
Learning Objects Metadata (LOM) aims at describing educational resources in order to allow better reusability and retrieval. In this article we show how additional inference rules allows us to derive additional metadata from existing ones. Additionally, using these rules as integrity constraints helps us to define the constraints on LOM elements, thus(More)
Digital Library support for textual and certain types of non-textual documents has significantly advanced over the last years. While Digital Library support implies many aspects along the whole library workflow model, interactive and visual retrieval allowing effective query formulation and result presentation are important functions. Recently, new kinds of(More)
Registration of scientific primary data, to make these data citable as a unique piece of work and not only a part of a publication, has always been an important issue. In the context of the project " Publication and Citation of Scientific Primary Data " funded by the German Research Foundation (DFG) the German National Library of Science and Technology(More)
Keywords: Metadata, Knowledge management, Internet technologies Metadata means data about data, structured data which describes the characteristics of a resource. The term " meta " derives from the Greek word denoting a nature of higher order or more fundamental kind. The term metadata was used long before the internet fundamentally changed our definition(More)
