This tutorial will help you understand how metadata is provided and used in SDIs. In particular, we will look at metadata based on ISO standards, as well as interfaces for querying and accessing metadata according to the OGC specification of Catalog Services for the Web (OGC CSW).
After completing this tutorial, you will be able to query and use OGC Catalog services via Python and QGIS.
The learning material consists of a PDF file that you can download from the /docs subfolder. As supporting materials, you will find the sources and data of the exercise in the /src and /data subfolders.
The learning material will guide you through practical exercises that require to download and install QGIS, DockerDesktop, Jupyter Server and a Python Notebook
The tutorial takes about 90 Minutes for reading and viewing the provided materials, downloading the software and for conducting the hands-on exercises and tasks.
This OER is primarily designed to be used by students in Geoinformatics, Geomatics and similar study programs. It is also useful for students of other study programs and for practitioners who want to enhance their understanding of SDI concepts and technologies. Some basic knowledge of web technologies such as HTTP and Web Services is required. However, you will be able to follow and find links to further resources if needed. Your computer should have 8 GB of usable RAM and 2 GB of usable disk space to download and use the software for this tutorial.
