AllegroGraph. AllegroGraph provides two different usage options: command-line interface (CLI) and a graphical user interface called AGWebView. The graphical user interface has limited functionality and does not support SHACL validation. Neither the import of the dataset represented in the N-Quads format nor the SHACL shapes written in Turtle yielded any problems.

To use SHACL in AllegroGraph, the command-line program agtool has to be utilized, which offers a variety of utilities. We used agtool to create a new database, import our dataset and shapes and perform the SHACL validation to obtain the report. It is important to note that the AllegroGraph’s SHACL implementation necessitates the explicit indication of all data graphs for the evaluation. The tool also allows to specify the output format of choice. We piped the output to the null device for a more precise time measurement. In Listing 1.3 the two generated violations can be seen. The only part missing from the generated violation is a sh:resultMessage, which could describe the violation in more detail.
