Hi,
For the last two years, we've been working on a project to harmonize disparate health data using the layered schema architecture and graph databases. Opencypher has been a key component of this project. We developed an open-source labeled property graph package and embedded openCypher implementation for Go language:
As of this writing, the openCypher implementation does not support all language features yet, but the core functionality is there.
Let me know if there are any questions about the packages.
Thanks.
