Four years ago this July, Google acquired Metaweb, bringing Freebase and linked open data to Google. It’s been astounding to watch the growth of the Knowledge Graph and how it has improved Google search to delight users every day.

When I moved to New York last year, I saw just how far the concepts of Freebase and its data had spread through Google’s worldwide offices. I began to wonder how the concepts would advance if developers everywhere could work with similar tools. However, there wasn’t a graph available that was fast, free, and easy to get started working with.

With the Freebase data already public and universally accessible, it was time to make it useful, and that meant writing some code as a side project.

So today we are excited to release Cayley, an open source graph database.

Cayley is a spiritual successor to graphd; it shares a similar query strategy for speed. While not an exact replica of it’s predecessor, it brings it’s own features to the table:
• RESTful API
• Multiple (modular) backend stores, such as LevelDB and MongoDB
• Multiple (modular) query languages
• Easy to get started
• Simple to build on top of as a library
and of course
• Open Source

Cayley is written in Go, which was a natural choice.
