Acknowledgements

The SchemaExplorer module (as a project under the TDA tool) has been developed with support from Latvian Science Council project lzp-2021/1-0389 "Visual Queries in Distributed Knowledge Graphs" (since 2022).

The TDA tool has been developed at Institute of Mathematics and Computer Science, University of Latvia, https://lumii.lv.
