Such information helps potential software developers and users make informed choices about packages that could advance their work in modeling, simulation, and analysis. At the same time, software presents novel challenges to information services that require the development of new methods and means of processing. swMATH provides users with an overview of a broad range of mathematical software and extends documentation services for publications related to such software. It acts as a counterpart to the established abstracting and reviewing services for mathematical publications and has nearly 30,000 entries, making it one of the most comprehensive documentation services in mathematics.}, language = {en} } @inproceedings{DalitzChrapary, author = {Dalitz, Wolfgang and Chrapary, Hagen}, title = {Software Products, Software Versions, Archiving of Software, and swMATH}, series = {Mathematical Software - ICMS 2018}, booktitle = {Mathematical Software - ICMS 2018}, doi = {10.1007/978-3-319-96418-8_15}, pages = {123 -- 127}, abstract = {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.}, language = {en} } @inproceedings{DalitzChraparySperber, author = {Dalitz, Wolfgang and Chrapary, Hagen and Sperber, Wolfram}, title = {Software Knowledge Management and swMATH}, series = {Fachgruppe Didaktik der Mathematik der Universit{\"a}t Paderborn}, booktitle = {Fachgruppe Didaktik der Mathematik der Universit{\"a}t Paderborn}, doi = {10.17877/DE290R-19281}, pages = {401 -- 404}, abstract = {Mathematische Software ist heute ein weitverbreitetes Werkzeug in der Forschung, aber auch in der mathematischen Bildung.

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.

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.}, language = {en} } @inproceedings{DalitzGroetschelLuegger1997, author = {Dalitz, Wolfgang and Gr{\"o}tschel, Martin and L{\"u}gger, Joachim}, title = {Information Services for Mathematics in the Internet (Math-Net)}, series = {15th IMACS World Congress 1997 on Scientific Computation, Modelling and Applied Mathematics, Volume IV}, booktitle = {15th IMACS World Congress 1997 on Scientific Computation, Modelling and Applied Mathematics, Volume IV}, editor = {Sydow, Achim}, publisher = {Wissenschaft und Technik}, address = {Berlin}, pages = {773 -- 778}, year = {1997}, language = {en} }
