Information Services for Mathematics in the Internet (Math-Net)
		Math-Net Subject Classification Scheme
		Deutsch

One aim of the Math-Net Project was to improve the access to the information for Mathematics in the WWW. Therefore, the contents of these information has been considered and a classification has been worked out, to which most of the contents can be assigned. A stage wise classification has been developed, where it was claimed to restrict the first stage to a few and important items. These are represented by the items: General, People, News, Research, Teaching, Information Services.
The first two stages of the introduced classification - the Math-Net Subject Classification - built the base of the locale Math-Net Guide and for the formulation of metadata sets.WWW documents with metadata provides a more qualified information retrieval as a free-text query can give. The Math-Net Searching Engine uses the metadata for a qualified search; a free-text query is also possible.

The Math-Net Subject Classification has been implemented as metadata by the "Math-Net Subject Classification Scheme" with Dublin Core Elements in HTML 2.0. For WWW documents with these special metadata (which can be easily add into existing documents) the searching space, on which a free-text search is done, can be much reduced, e.g. by using the Example Search Interface.

Explanation:

Pages can be classified by the Math-Net Subject Classification scheme if they belong to one of the categories (based on the Math-Net Guide)

	General    About us    Organization    Beginner's Guide    Visitor Service		Research    Research Groups    Preprints    Publications    Projects    Software
	People    Faculty / Staff    Students		Teaching    Curricula    Lectures    Course Materials
	News    Communications    Positions    Schedule of Events		Information Services    Library    Bibliographic Search    Electronic Journals    Software Libraries

    Such pages should be at least complemented by metadata of the form

	<META  NAME="DC.Subject"  CONTENT="(SCHEME=MathNet)	Field	.	Subfield	">
	e.g. for course materials
	<META  NAME="DC.Subject"  CONTENT="(SCHEME=MathNet)	Teaching	.	CourseMaterials	">
	These metadata has to be supplemented by the location of the Math-Net Subject Classification Scheme by the entry
	<LINK REL="SCHEMA.MathNet"
	HREF="http://www.mathematik.uni-osnabrueck.de/ak-technik/MathNet/BasicMeta.html">

Remark:

• These metadata can easily generated and brought into HTML-Pages by the MetaTool.

• The scheme includes further the entries

  	General	.	Start		for the Local Math-Net Guide
  	General	.	Homepage		fpr the homepage of the institution

• More than one classification of a document are possible.
