Neo4j is being used by Bert, a developer, as part of his projects in the Netherlands and New York. He worked on a geocoder search engine for historical place names with Neo4j as one of the backends, creating a graph of place names and historical place names to tackle the issue of changing names over time. The project, called Histograph, aimed to create a common ground for talking about identifiers of those names. Bert also mentioned that he chose Neo4j because of its active community, clear plans for development, and great libraries with good documentation and support from Stack Overflow. He noted that some features, such as indexing edges, are currently not possible in Neo4j but are expected to be added in future editions. Bert is now working on the Space/Time Directory project at the New York Public Library, aiming to create a digital time machine to travel through the library's collection and connect users with rich materials using APIs and graph databases.
