Over the past years, several software development teams in the IT Center have continuously improved their development processes. One of the most significant changes was to select GitLab as the central tool for the software-development-life-cycle and to enhance certain processes with the help of this tool in the areas of planning, implementation, in...

The availability of large amount of digital data, computational power combined with new approaches of dataanalysis and so called artificial intelligence created the potential of new scientific discoveries in almost all scientific fields.However, to realize the potential a number of challenges need to be addressed. The amount, quality and accessibil...

Extracting interoperable metadata from data entities is not an easy task. A method for this would need to extract non-interoperable metadata values first and then map the extracted metadata to some sensible representation. In the case of HDF5 files, metadata annotation is already an option, making it an easy target for extracting these non-interope...

Research Data Management (RDM) systems are becoming an essential part of every researcher's academic career. Often, researchers use various resources and web applications to handle their research data, causing complications for maintaining data and assessing research projects against FAIR principles. Consequently, RDM platforms help researchers wit...

Many provenance systems assume that the data flow is being directly orchestrated by them or logs are present which describe it. This works well until these assumptions do not hold anymore. The Coscine platform is a way for researchers to connect to different storage providers and annotate their stored data with discipline-specific metadata. Thes...

In response to the growth of demand for web services, there is a rapid increase in distributed systems. Accordingly, software architects design components in a modular fashion to allow for higher flexibility and scalability. In such an infrastructure, a variety of microservices are continuously evolving to respond to the needs of every application....

Many research data management processes, especially those defined by the FAIR Guiding Principles, rely on metadata for making it findable and re-usable. Most Metadata workflows however require the researcher to describe their data manually, a tedious process which is one of the reasons it is sometimes not done. Therefore, automatic solutions have t...

With CoScInE, the Collaborative Scientific Integration Environment, we present a software platform to allocate and manage IT resources in research projects. While the platform itself does not store any research data, it enables integration of multiple storage resources and allows metadata management across these resources. This supports researchers...

Allowing students to use their own devices for electronic assessments allows institutions of higher education to reduce their expenses for specialized computer labs. There are, however, concerns about the security of these kind of examinations if the devices are not fully controlled by the examining institution. In addition to these concerns, sever...

Our daily life is characterized by an increasing number of process supporting IT services. With wireless and mobile networks, all kinds of devices are connected to the Internet and constantly access, collect and exchange data with various IT services to instantly provide information. The increasing volume and heterogeneity of computer devices requi...

A Moodle-based e-learning system will replace RWTH Aachen University's SharePoint-based e-learning system, which was introduced 10 years ago, within the course of digitizing teaching processes. The strategic background for the university management is that in the competition for students, teaching must become more attractive through innovative form...

Evolutionary changes are often used to gradually increase the quality of a software. However, if back-end systems have to be replaced with different technologies, the resulting changes are more radical. One example for such a change is the migration of database servers from a relational to a document-oriented storage engine. Based on an example app...

Universities IT service providers are faced with rising demands on existing IT systems and higher degrees of individualization. The challenge thus is to provide services that researchers can use today but that are flexible and sustainable enough to also support tomorrows' research processes. Emerging from previous projects supporting administrative...

Learning spaces at universities are limited in their capacity, while, providing more such places to students, often imposes quite some problems to the responsible institutions. This leads to problems for the students finding adequate space to conduct their studies on the campus. The consequences are, e.g. large queues of students waiting in front o...

To reduce the impact of security vulnerabilities of Eduroam the Eduroam Device Management was implemented at RWTH Aachen University.
