Various XML-based approaches aimed at representing complex digital objects have emerged over the last several years. Approaches that are of specific relevance to the Digital Library community include the Metadata Encoding and Transmission Standard (METS), the IMS Content Packaging XML Binding, the Sharable Content Object Reference Model (SCORM), and the XML(More)
Although the OAI-PMH specification is focused on making it straightforward for data providers to expose metadata, practice shows that in certain significant situations deployment of OAI-PMH conformant repository software remains problematic. In this paper, we report on research aimed at devising solutions to further lower the barrier to make metadata(More)
This paper focuses on the use of NISO OpenURL and MPEG-21 Digital Item Processing (DIP) to disseminate complex objects and their contained assets, in a repository architecture designed for the Research Library of the Los Alamos National Laboratory. In the architecture, the MPEG-21 Digital Item Declaration Language (DIDL) is used as the XML-based format to(More)
A meeting was held in Santa Fe, New Mexico, October 21-22, 1999, to generate discussion and consensus about interoperability of publicly available scholarly information archives. The invitees represented several well known e-print and report archive initiatives, as well as organizations with interests in digital libraries and the transformation of scholarly(More)
The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital(More)
The identification of the candidate genes for autism through linkage and association studies has proven to be a difficult enterprise. An alternative approach is the analysis of cytogenetic abnormalities associated with autism. We present a review of all studies to date that relate patients with cytogenetic abnormalities to the autism phenotype. A literature(More)
In Belgium, we developed a digital long-term preservation archive to preserve the information from our heritage institutions. This platform harvests the information from the institutions, preserves the information for the long term and disseminates the information as Linked Open Data. Our platform produces many different versions of the harvested data to(More)
This paper introduces the write-once/read-many XMLtape/ARC storage approach for Digital Objects and their constituent datastreams. The approach combines two interconnected file-based storage mechanisms that are made accessible in a protocol-based manner. First, XMLbased representations of multiple Digital Objects are concatenated into a single file named an(More)
An X chromosome specific nucleic acid probe was used to study the positions of the X chromosomes in leukocyte nuclei by in situ hybridization to smears of peripheral blood. This autoradiographic approach allowed the first direct demonstration of the presence of X chromosomal material in the drumstick-like structures of female polymorphonuclear leukocytes.
