Zeyton remains our biggest project. We took on the task of building a knowledge graph. We worked with what is now Amazon Neptune team (Blazegraph) to rebuild www.freebase.com. We aimed at creating a scalable knowledge graph that could scale as large as Wikidata/Freebase itself. Freebase is now Google Knowledge Graph. The scale of such a project and graph database requires scalable fron-tend down to the very configuration of hardware. The project was discontinued by those who funded it and www.zeyton.com should no longer point to the project.
