The Howdy Glossary

Gremlin is a graph traversal programming language for querying and updating property graphs. The query language uses steps, each of which performs a transformation on the data structure. It's part of the Apache TinkerPop graph computing framework and allows users to write code that works with any Blueprints-enabled graph database through its Gremlin Server. As an open-source project, Gremlin also provides a machine-generated JavaDoc documentation together with user-contributed documentation in the form of tutorials and blog posts.
