With an ever growing body of scientific knowledge and an explosion of data generated by computer-based experiments, the Findability, Accessibility, Interoperability and Reusability of research data (FAIR principles) become key factors for further scientific progress. In Scientific Computing, beyond the actual simulation data the developed numerical algorithms, their implementations, procedural data, and their metadata descriptions are central research data. Establishing the FAIR principles for this data is the aim of the task area 'Scientific Computing' within the German Mathematical Research Data Initiative MaRDI.

With this second MaRDI Workshop on Scientific Computing, we want to bring together researchers from the Scientific Computing community and related disciplines, who are interested in the FAIRness of their research data. Apart from presentations on the current MaRDI projects and selected keynote talks, birds-of-a-feather sessions will leave room for discussions and hands-on tutorials. Further, we invite participants to contribute talks related to the following topics:

• Knowledge graphs and ontologies
• Software Interfaces
• Benchmarks
• Formal workflow descriptions
• Software distribution and archival
• Reproduction of numerical experiments
• Research data management

Participants are encouraged to present work in progress, open problems or report on personal experiences.

Scope
The NFDI_BB meetings aim at setting up a network of all the NFDI consortia located in the Berlin-Brandenburg area. At the successful kickoff meeting last October, the topic “Ontologies and Knowledge Graphs” was identified as a central task overarching the consortia, so that we will now dedicate ourselves to this topic. Particular focus will be on potential cooperation between the projects from consortia in different disciplines.

Agenda
During the morning session, the topic “Ontologies and Knowledge Graphs” will be presented in connection with the activities of the NFDI in several talks. In the afternoon session, we will continue with short presentations on ontology concepts of the individual NFDI consortia. These will then be further explored in interactive discussion formats.

Scope
Every researcher in every research discipline has research data. Only, you may not call it data (yet).

To generate new math results, we build on previous results, perform own observations and thought experiments, try and fail many times until a proof is completed, find a little help from a colleague, and maybe use a computer to run a quick or complex computation. Isn’t all this just collecting data?

In this one-day course that was specifically designed for researchers in mathematics, we will learn and experience what mathematical research data is and how we can organize, document, and possibly publish it.

The workshop has been rescheduled to November 23rd and Registration is still open.

Abstract
As mathematics becomes more and more digital and algorithms, proof assistants, and digital databases become more and more involved in mathematical research, the question arises how
to handle this mathematical research data that accumulates alongside a publication; how it can be stored, made accessible and reused. How can a certain quality be ensured? What services can be build that support scientists in their daily work? What role does the Mathematical Research Data Initiative (MaRDI), the NFDI consortium of the mathematical community, play in this process?

In this minisymposium we will highlight first solutions and services that help researchers in writing proposals, documenting their workflows, storing their data, and accessing mathematical knowledge to facilitate their work and foster connections between different researchers. The components that have been recently deployed illustrate how an interconnected infrastructure of mathematical research data takes shape.

Speakers will share their experience with existing solutions and present services that are currently developed with a focus on MaRDI.

Scope
Supported by the Bielefeld Center for Data Science (BiCDaS) and the Competence Center for Research Data at Bielefeld University MaRDI will host a Barcamp on research-data management in mathematics on July 4th 2023 at the Center for Interdisciplinary Research (ZiF) in Bielefeld.

The event will provide a forum to exchange expertise and questions in the field of mathematics-specific research-data management and existing best practices. It is aimed at all researchers dealing with mathematical research data as well as at people from large mathematical research projects such as CRCs, priority programs or clusters of excellence. In a Barcamp, the topics are decided on by the participants. This means that the focus will be very specific to the research questions and needs of the attendees. Questions could be: "What exactly does your community need?", "What works well and what doesn't?" or "How do young researchers or young projects implement 'good' RDM structures in the first place and what has proven successful?"

Making research software FAIR and citable
There is growing acknowledgment that software constitutes a valid research output. As such, it must be made available under the FAIR Principles for Research Software (FAIR4RS). Software publication with rich metadata allows researchers to provide their software in such a way, thus enabling better reproducibility of research results obtained using software, more credit for research software creators through citation, and improved sustainability. Currently, FAIR software publication is not common practice due to a lack of incentives, of clearly defined processes, and of publication support through tools and infrastructures. This talk presents the context of, and practical approaches to, automated FAIR4RS software publication: improving citation metadata for research software with the Citation File Format, and automating software publication with rich metadata using the HERMES workflow for continuous integration systems.

Building research data services for the community
MaRDI is the Mathematical Research Data Initiative. Its goal is to contribute services and infrastructure for mathematical research data to the German National Research Data Infrastructure. Having started in 2021 now first services emerge that are supposed to easy the management of research data for mathematicians and scientists that use math. In this talk, we will introduce some of them and relate them to the overall goals of MaRDI.

MaRDMO - An RDMO plugin to document and query MSO Workflows using the MaRDI Knowledge Graph
The Mathematical Research Data Initiative (MaRDI) has set itself the goal of making information about mathematical objects, e.g. algorithms or models, available in a structured and easy-to-find manner in the form of a knowledge graph. The linking of all these objects with concrete research questions, input and output data, software and hardware is done in specific model-simulation-optimization workflows. To achieve reproducibility of these, often interdisciplinary, workflows, detailed documentation is required. For this purpose, a standardized workflow documentation template was developed in the MaRDI project, which can be completed by answering a simple questionnaire in RDMO. Workflows recorded in this way can be published directly on the MaRDI portal. In addition, central information of the documentations is integrated into the MaRDI Knowledge Graph. Next to the pure documentation of workflows, MaRDMO offers the possibility to retrieve existing workflows from the MaRDI Knowledge Graph in order to provide researchers with suggestions for future projects and to document workflows based on these suggestions. Thus, MaRDMO creates a community-driven knowledge loop that could help to overcome the replication crisis.

Scope
Discrete mathematics has a long-standing tradition of generating and utilizing data to substantiate theories. Conversely, questions regarding the systematic generation of (counter-)examples drives research.

This 2-day “noon-to-noon” workshop is dedicated to the interplay of discrete data and discrete structures from a contemporary perspective. How FAIR is our data? How can modern technology help to analyze and interpret discrete data? Which connections to the sciences become visible through data? We approach these questions “hands-on” with invited lectures and panel discussions.

Abstract
As part of a major effort by the German Research Foundation to build a sustainable research data infrastructure, the MaRDI (mathematical research data initiative, www.mardi4nfdi.de) consortium has been established to represent mathematics and certain parts of computational engineering in this program. One of MaRDI's tasks is to develop concepts, tools, and infrastructures that enable the establishment of FAIR principles (findable, accessible, interoperable, and reusable) for research data in scientific computing.

In this minisymposium, with knowledge graphs, software interfaces, benchmarks, and workflows as common ground, we bring together developers of the relevant MaRDI projects and researchers and practitioners from the CSE community to discuss general concepts and showcase lighthouse projects to the community.

Research questions developed using digital methods in philosophy, as well as the humanities, cultural studies and history are complex. The approach to answering the questions often requires careful planning of the research process, including the selection of objects to be studied. At various levels (propositional logic, experimental design, pattern recognition, graph theory), the planning and execution tangentially involve topics that can also be located in modern mathematics. It is therefore important to find a form of communication with mathematics that allows non-mathematicians to identify the useful tools of mathematics.
The laboratory DIHMA.LAB "Digital Humanities meet Mathematics" of the ADA Lovelace Center for Digital Humanities at the FU Berlin invites together with MaRDI, the Research Data Initiative of Mathematics, to a workshop in Berlin.

The first workshop in this constellation will primarily serve to get to know each other, to network, and to identify interfaces. The starting point should be what the disciplines would call their own "research data" and how they want to "deal" with it.

We assume that the participants from the (digital) humanities and the participants from mathematics will enter this workshop with certain expectations of the other discipline. Therefore, an exchange on a scientific, practical-technical and research-cultural level is aimed at questioning expectations and creating (also technical) interfaces for an efficient collaboration.

Abstract
As mathematics becomes more and more digital and algorithms, proof assistants, and digital databases become more and more involved in mathematical research, the question arises how to handle this mathematical research data that accumulates alongside a publication; how it can be stored, made accessible, and reused. How can a certain quality be ensured?

These are not easy questions, since mathematical research data is very diverse and infrastructure is just developing. But there are many great ideas and visions in the community that will be highlighted in this mini symposium. Next generation peer review, the Mathematical Knowledge Graph, repositories for mathematical research data, benchmark services, … to name a few.

Speakers will share their experience with already existing solutions and their visions and plans for how a well-developed integrated infrastructure can further facilitate mathematical research. A focus will be on the Mathematical Research Data Initiative (MaRDI), the NFDI consortium of the mathematical community, that will develop a portal for mathematical research data with many services in the next years.

The MaRDI portal for mathematical research data
Mathematical research data (MRD), arising in many scientific fields, encompass widely different types of data and can be vast and complex, e.g., numerical data sets, mathematical expressions, algorithms, etc. The NFDI MRD Initiative (MaRDI) aims to define standards for MRD, to design verifiable workflows and to provide services to the scientific community. The services will be bundled in a web portal, allowing researchers to easily find and access mathematical research data, knowledge and services. In addition, the portal will offer storage capacities and host services for workflow and algorithm execution. At the core of the portal lies a mathematical knowledge graph which organizes and interconnects data from multiple sources. The main contribution of the portal is providing a unified entry point to access scattered and unconnected data. This talk gives an overview of the current status and planned features of the portal, and its value for the mathematical community.

Overview and discussion of the progress of math search technologies
The number of scientific publications containing mathematical expressions is immense and constantly growing. For example, zbMATH Open, the world's longest-running abstracting and review service for mathematical content, indexes over 160 million formulas. Mathematical formula search is a core technology for finding scientific documents where formulas are defined as input. Since the introduction of many mathematical search systems in the NTCIR Math-Task series from 2013, there have been further advances and implementations of formula search. In the first 15 minutes of our talk, we want to provide an overview of current methods of formula search and related applications. According to the FAIR principles, we will emphasize aspects of reusability and accessibility here. Then, for the next 10 minutes, we intend to reach out to the audience and have a lively discussion on the planned efforts and experiences of the community with formula search.

Abstract
Have you seen yourself typing $$ in an Email or did you miss the possibility to search for a mathematical formula in Google? If yes, you are already on your way to become a digital mathematician. The good news is, you are not alone and many mathematicians also use computers to obtain mathematical results.
The mathematical research data initiative (MaRDI) in Germany aims to connect those people and facilitates the sharing and finding of mathematical research data and mathematical knowledge. MaRDI aims to establish best practices and low-barrier infrastructures for mathematicians to better organize and access large amounts of data and knowledge. MaRDI aims to integrate individual results, e.g., as contained in a paper, into a common knowledge base like Wikipedia. In this minisymposium, we present the state-of-the-art and lessons learned from practical experience in handling mathematical research data and information. We invite mathematicians to share and discuss their experiences, needs, concerns and perspectives on the digital transformation and the innovations necessary to drive it across all levels of the mathematical ecosystem covering students, researchers, reviewers and funding bodies.
