Sharing Knowledge: Scientific Communication - SSOAR

prints werden durch die Nutzung von Metadaten verbessert. Die qualitative Suche
wird auf diese Weise sehr effektiv.
Die Entwicklung von Metadaten Schemata und Metadaten Codierung zwingt
uns nun vom flachen HTML-META tag zum detaillierten Resource Description
Framework (RDF) überzugehen, wie es vom W3C empfohlen wird.
Der Artikel skizziert MPRESS und die Entwicklung der Metadaten Codierung.
Die Probleme, die sich für ein System wie MPRESS aus einer Umstellung
des zugrundeliegenden (Meta)Datenformates ergeben, werden diskutiert und
Lösungsansätze sowie die resultierenden Verbesserungen werden vorgestellt.
Introduction
For a long time mathematicians used to circulate preprints and exchange ideas
within small circles.
Today, however, mathematicians and other scientists put their scientific results
on departmental WWW-Servers in forms of preprints, or they send it to
preprint servers like arXiv.org to avoid the long period of time between the submission
of an article and its publication in a scientific journal.
However, it soon became obvious that this large amount of data was hardly
useful just as a set because people only knew how to find their own preprints.
But how could he or she find preprints of a colleague at university X or preprints
on a certain topic?
Large search engines in the internet, like Alta Vista or Google, are not well
adapted to finding specific scientific material because scientific material only
covers a very small part in the set of all internet documents and resources.
What today’s mathematicians need in order to retrieve scientific information
from the web is a specific way of searching for information. This is provided by
metadata and their specific ways of navigating. Part of this is given by the Mathematics
Subject Classification (MSC).
The Math-Net project in Germany [Dalitz, 1997] was designed to answer these
needs and it was conceived as a first step in order to design and implement a
worldwide electronic information and communication system for mathematics
and to turn Math-Net into an international endeavor.
MPRESS, which is supported by the Math-Net Project, started under the auspices
of the European Mathematical Society. The CEIC (Committee on Electronic
Information and Communication), which is established by the International
Mathematical Union (IMU), has designated MPRESS as a Math-Net service.
In 1995 the Dublin Core Initiative proposed the formal description of documents
by using the Dublin core 15 elements. The idea was to store these metadata
in the head of HTML files by using the HTML META tag. MPRESS was
