Data Collections Explorer – An Information System for the Engineering Sciences

The poster provides an overview of and an introduction to the Data Collections Explorer. It is an information system for engineering related resources, such as repositories, databases, archives, as well as datasets published independent of these structures. In addition, the poster describes current developments and provides an outlook on future work.

The target audience are scientists either searching for data sets or looking to publish their data sets.
Seeking to share or publish their research data sets, scientists are confronted with questions such as: what is an appropriate repository for publishing the data sets? Do repositories have size restrictions with respect to the data sets that can be uploaded? What is this limit? Are publication fees charged?
Searching for data sets, scientists are often confronted with questions such as: are data sets available to aid in research? Are benchmarks available to check results? Are these data sets available under an open access license?

The Data Collections Explorer is a low-threshold web service to share and discover research data. To help get an overview and answer the above questions, it provides a free-text search as well as drop-down menus to filter its entries for the following criteria:

A stable version is currently in use by NFDI4Ing (https://data-collections.nfdi4ing.de). The current development version features a graph-based data model. A preview version will be made available later this year. This knowledge graph can be accessed by a SPARQL interface. It provides more flexibility than the currently deployed version.
