Current engineering design processes oftentimes involve transferring information from manufacturer-provided data sheets into domainspecific design tools.While most data sheets are provided only as PDF files, this remains a tedious and manual task.This paper presents the Data Sheets Annotation Tool (DSAT), which assists engineers in gathering the information required in the design process.Using an Ontology-Based Information Extraction (OBIE) method, the properties of components are extracted from data sheets and subsequently presented in an integrated, web-based interface.Engineers can now review and correct these automatic annotations, before exporting them for further use.In the demonstration, we employ a real-world use case rooted in modelbased space-system engineering.We show how the automated process can extract relevant component-attributes from technical data sheets and how users can redact the results.We further highlight the impact of content and quality of the underlying ontologies.
