In this paper, the concepts and design for an efficient information service for mathematical software and further mathematical research data are presented. The publication-based approach and the Web-based approach are the main building blocks of the service and will be discussed. Heuristic methods are used for identification, extraction, and ranking of information about software and other mathematical research data. The methods provide not only information about the research data but also link software and mathematical research data to the scientific context.

swMATH is currently one of the most comprehensive specialized information services and search engines for Mathematical SoftWare (MSW). It was the intention of the project to support the user community by providing infor- mation about MSW and searching relevant MSW. Currently swMATH lists infor- mation of more than 13,000 items and 120,000 publications which refer to MSW. Maintaining and updating of the service is mainly done automatically, the num- ber of requests is permanently increasing. This sounds like a perfect solution. But swMATH is only a first step to a powerful information system on mathematical research data. This talk addresses some open problems for the further develop- ment of the swMATH service. It is shown that some problems for swMATH lead to central questions for the information management of mathematical research data, especially for MSW. This contains an extended content analysis of MSW, versioning and citation standard of MSW, a typing of the swMATH resources and the presentation of context information and high-quality control within the swMATH service.
Management of software information is difficult for various reasons.
First, software typically cannot be reduced to a single object:
information about software is an aggregate of software code,
APIs, documentation, installations guides, tutorials, user interfaces,
test data, dependencies on hardware and other software, etc.
Moreover, secondary information about software, especially use cases
and experience with employing the software, is important to communicate. Second, typically named software, which we term here a `software product', is taken to stand for all versions of the software which can have different features and properties and may produced different results from the same input data.
Software production is a dynamic process and software development is, increasingly, widely distributed. Therefore GitHub, GitLab, Bitbucket and other platforms for sharing are used. Information about software is alos provided in different locations, on websites, repositories, portals, etc. Each resource provides information about software from a particular point of view, but the information is often not linked together. Therefore swMATH has developed a conception which covers portals and a search engines for mathematical software, persistent
and citable landing pages for specific software, and a method for software archiving. Based on the publication-based approach, swMATH collects and analyses semi-automatically the existing information about mathematical software found on the Web and makes it available
in a user-oriented way.
Mathematische Software ist heute ein weitverbreitetes Werkzeug in der Forschung, aber auch in der mathematischen Bildung. Die Anzahl mathematischer Softwareprodukte wächst, nicht zuletzt durch die Anforderungen der Anwender, stark. Anders als für mathematische Publikationen sind für das Management mathematischer Software viele Fragen offen und werden noch diskutiert, etwa die Standardisierung von Software Zitationen. Der Aufbau einer effizienten Infrastruktur für Software ist eine notwendige Voraussetzung für die Überprüfung von Forschungsergebnissen, die mittels Software erzielt worden sind und wichtig für die Entscheidung, ob eine bestimmte Software zur Lösung eines Problems verwendet werden soll. Das swMATH [1] Portal gibt einen weitgehend vollständigen Überblick über die existierende mathematische Software. Es ist ein Dienst entstanden, der automatisiert die im Web vorhandenen Informationen zu einer Software identifiziert, auswertet und verfügbar macht. Der Dienst soll insbesondere durch die Verknüpfung mit anderen Quellen, etwa dem Internet Archive, persistente Informationen über ein Software Produkt und dessen Versionen liefern.
Der Informationsaustausch in den Wissenschaften befindet sich in einer Umbruchsituation. Traditionelle, papiergebundene Publikationsformen werden durch elektronische Medien ergänzt und sogar abgelöst. Moderne Client/Server basierende Systeme und Zugriffswerkzeuge erlauben heute völlig neue Distributions- und Kommunikationsformen. In einem vom DFN und der Deutschen Telekom geförderten Projekt geht es in der vorliegenden Vorhabenbeschreibung um die konkrete inhaltliche und organisatorische Planung, ein umfassendes, möglichst alle mathematisch relevanten Ressourcen berücksichtigendes, Informationssystem für die Mathematik aufzubauen.
The present paper gives a brief description of the Math-Net project which is carried out by nine mathematical institutions in Germany, supported by Deutsches Forschungsnetz (DFN) and Deutsche Telekom. The project aims at setting up the technical and organizational infrastructure for efficient, inexpensive and user-driven information services for mathematics. With the aid of active (structured retrieval mechanisms) and passive (profile services) components, electronic mathematical information in Germany will be made available to the scientist at his workplace. The emphasis is put on information about publications, software and data collections, teaching and research activities, but also on organizational and bibliographical information. Decentral organization structures, distributed search systems as well as the use of meta-information (metadata) in accordance with the Dublin Core (hopefully) guarantee a longterm, high-quality repository of data. The well-known mathematical software and data collection netlib\/ will be used as an example to illustrate how such a collection can be adapted to Math-Net. An integration of netlib into HyperWave offers additional perspectives and functionalities.
``Das System ist zerbrochen!'', so lautet das Urteil von Keith Dennis, Professor an der Cornell University und neuer Verantwortlicher für die Mathematical Reviews, über das traditionelle Publikationswesen in der Mathematik. Was sind die Ursachen? Hauptsächlich sind es das starke Wachstum der mathematischen Literatur, die langen Verzögerungen von der Erstellung bis zum Erscheinen einer Arbeit, die hohen Ablehnungsraten bei mathematischen Journalen aufgrund beschränkter Seitenzahlen (und nicht wegen mangelnder Qualität) sowie drastisch steigende Preise für Zeitschriften und Bücher bei gleichzeitiger Reduktion der Bibliotheksetats.
"The system is broken'' is how Keith Dennis, professor at Cornell University and the new editor-in-chief of the Mathematical Reviews characterizes the traditional ways and means of publication in mathematics. What are the reasons? The main reasons are the extreme growth in the mathematical literature, the long delays between preparation and publication of an article, the high number of rejected papers due to page limitations (not lack of quality) as well as drastic price increases for journals and books with library budgets being reduced at the same time.
