RDFShape server has been implemented in Scala using the following libraries:

• SHaclEX: a Scala implementation of ShEx and SHACL.
• http4s: a purely functional library for http.
• cats: a library for functional programming in Scala.
• Logback with Scala Logging: logging framework.
• scallop: a simple command-line arguments parsing library for Scala.
• UMLShaclex: contains the visualization code that converts schemas to UML diagrams.
• SRDF: is the library used to handle RDF. It is a simple interface with 2 implementations, one in Apache Jena, and the other in RDF4j.
• Any23: is used by RDFShape to convert HTML files in RDFa and Microdata to RDF.
• Topbraid SHACL API: is used to add another SHACL engine apart of the SHaclEX and Apache Jena SHACL engines.
