Abstract
Die seit ca. 1996 rasche Entwicklung des Internet bzw. des World Wide Web (WWW) hat die Praxis der Veröffentlichung, Verbreitung und Nutzung wissenschaftlicher Informationen grundlegend verändert. Um diese Informationen suchbar und retrievalfähig zu gestalten, ist in den letzten Jahren international viel diskutiert worden. Ein vielversprechender Ansatz, diesen neuen Herausforderungen zu begegnen, liegt in der Entwicklung von Metadatenprofilen. Da durch das Internet verschiedene Datenbestände, die von unterschiedlichen Bereichen wie Museen, Bibliotheken, Archiven etc. vorgehalten werden, unter einer Oberfläche durchsucht werden können, können Metadaten auch in diesem Bereich dazu beitragen, ein einheitliches Konzept zur Beschreibung und zum Retrieval von Online-Ressourcen zu entwickeln. Um die verteilt liegenden Dokumente unter einer Oberfläche für eine qualitativ hochwertige Recherche ("Cross-Search`) anbieten zu können, ist die Verständigung auf ein Core-Set an Metadaten und daran anschließend verschiedene Mappingprozesse ("Cross-walk`) von den lokalen Metadatenformaten zu dem Format des Core-Set an Metadaten notwendig. Ziel des Artikels' ist es, die einzelnen Schritte, die für die Entwicklung eines Metadatenprofils für die gemeinsame Suche über verteilte Metadatensammlungen notwendig sind, aufzuzeigen.
Content
Die vorliegende Arbeit wurde als Hausarbeit am Institut für Bibliothekswissenschaft im Rahmen eines Postgradualen Fernstudiums an der Humboldt Universität im Frühjahr 2001 angefertigt. Der erste Teil dieser Arbeit, der sich mit cross-searchen beschäftigt, wird hier in gekürzter Fassung veröffentlicht.
