Summary
This article deals with semantic modelling and Linked Geodata in context of the COVID-19 pandemic. These new technologies of interoperable and Linked Data management are becoming more and more popular in the geo sector and are used worldwide, both by administrative institutions and by independent voluntary communities as Volunteered Geographic Information (VGI). In the course of the COVID-19 pandemic, publishing (geo)data is of central importance. This article shows the background and possibilities of semantic and Linked Open Data technologies using Wikidata. As a result of this process, an ontology is presented, that homogenizes different data qualities and data sources. Results of this COVID-19 data modelling can be visualized as Linked COVID-19 data in an explorer or by using a QGIS plugin.
