A graph database on top of tokyocabinet and libevent

About

Vertex is a high performance graph database that supports automatic garbage collection, built on libevent and tokyocabinet. It uses HTTP as it's communication protocol and JSON as it's response data format. It's BSD licensed and was written by Steve Dekorte and Rich Collins. See docs/manual.html for API and more details.
