About this Talk
Knowledge Graphs are a crucial enabler for breaking down data silos. With Knowledge Graphs, we can connect various data sources, translate them to a common data language, and then use this newly created repository to answer the pressing business questions of today and tomorrow.
RDF is particularly well-suited as the underlying stack for your data integration. It is standardized by the W3C, the same organization that also standardized XML, HTML, or CSS. That means the data you create is guaranteed to be usable for the long term and independent of tool vendors; thus, it can easily be exchanged with different systems.
This masterclass gives you an overview of RDF and the underlying concepts. First, we learn the basics: To describe our world with triples and how these triples form a graph. Afterward, we learn how to use fixed vocabularies to add semantics that humans and computers can understand. Finally, we delve into SPARQL to get the data we created out of our system.
This masterclass is fully interactive. We will use an online SaaS coding sandbox based on VS Code to create RDF. We will see how the data directly corresponds to a created graph representation and also be able to query data.
This course targets knowledge graph beginners who want to go into a hands-on session to explore how to create graph data themselves. After this course, the participants should be able to (1.) read and alter RDF (2.) justify the use of standardized vocabularies for data understandability (3.) query the data using SPARQL.

Format
While we give a brief presentation at the beginning of the course, most of the time will be spent on an interactive session working with RDF.
We will work with the neonto coding sandbox: A VS Code-based SaaS editor with everything needed to start a knowledge graph development project. We will create our first RDF statements and iteratively create an RDF graph.
The masterclass will start with a brief presentation on the fundamental concepts of RDF, but we will quickly move to hands-on coding exercises. Here, all participants get their pre-installed coding environment with the necessary plugins. There, we will create the first RDF data, see visually how a graph evolves, and then
