Generating RDF-Graphs with simple CSV files – RDFier

Your data is stored in a relational database or in a spreadsheet, and you want to generate Resource DescriptionFramework (RDF) data out of it? With the open-source tool RDFier [1], one can easily transform a CSV file intoRDF. The main task is to set the column names correctly. This way, the tool can handle different datatypes, languages,and blank nodes, and it also allows the usage of prefixes for abbreviation.Another reason for the creation of the tool was to provide different ways to model uncertain data in RDF. By adding“^^certainty“ at the end of a column name, one can specify a column as such and can select out of eight differentmodeling ways that are 100% in RDF. In addition it provides two ways to model it in RDF-Star.We will present the tool that was generated by Jan Luca Pöpperl in the context of his master’s thesis [2], with someuse cases to show its potential.[1] Jan Luca Pöpperl: RDFier (2023) License: CC-BY-NC-4.0 https://github.com/poepperl/rdfier[2] Jan Luca Pöpperl: Modellierung von Unsicherheiten in Daten: Benchmarktests verschiedener Ansätze (2023): https://github.com/UncertaintyC/unco/blob/42a561ca68543ffbde32e953cd71f18093628824/master_thesis.pdf
