Progress in science bases on the availability and accessibility of the state of
the art. In mathematics and related sciences this state of the art is reflected
in form of preprints that are nowadays published electronically. Since every
author becomes his or her own publisher there is a lack of organizing
accessibility of the material.
The same problem of missing organization we find when searching for people or
teaching material in a specific area on the Web. MathNet deals with this
problems and tries to solve them in a user driven approach.
The talk briefly introduces MathNet and explains techniques and developments
on the basis of MPRESS - one of the MathNet services:
The Mathematics PREprint Server System (MPRESS) is a service offering an index
of mathematical preprints electronically published all over the world.
Referencing more than 50.000 documents residing on more than 100 WWW servers
MPRESS is the largest index of mathematical preprints worldwide. The index data
of the preprints are enriched by the use of metadata which improve the quality
of retrieval drastically.
The development of metadata schemes and encoding forces a transition from plain
metadata to RDF as recommended by W3C.
The talk sketches the system MPRESS and the related development in the area of
metadata. The problems that these developments cause for a system like MPRESS
as an example of a MathNet Service
are discussed and the transition to a new metadata scheme is presented as well
as the improvements that result from this transition.
