What is the Libre Manufacturing Data Platform?

Libre is an Open-source, Data Science ready continuous improvement and Manufacturing Execution Platform.

The Libre platform allows you to:

connect to your Manufacturing data sources
model your equipment, and the data that your equipment provides
store machine data in a specialised time-series database with full context from your equipment model
Define rules for capturing event data from your equipment, and store that event data in the time-series database with context
Define Materials and recipes that describe the way products are manufactured in your plant
Access all of your data through an open GraphQL API including the equipment and material models along with data from the time-series database

The Libre Platform is an Event-Driven Micro-services architecture written in Go.

The Frontend UI application communicates primarily through the GraphQL gateway, and receives event notifications directly from the event bus.

Apollo Federation is used to compose a single GraphQL schema from multiple graphql services

Non time-series data is stored in Dgraph which is a GraphQL native database platform.

Prereqisites:

For any issue, there are fundamentally three ways an individual can contribute:

By opening the issue for discussion: For instance, if you believe that you have uncovered a bug in libre-common, creating a new issue in the GitHub issue tracker is the way to report it.
By helping to triage the issue: This can be done either by providing supporting details (a test case that demonstrates a bug), or providing suggestions on how to address the issue.
By helping to resolve the issue: Typically, this is done either in the form of demonstrating that the issue reported is not a problem after all, or more often, by opening a Pull Request that changes some bit of something in the simulator in a concrete and reviewable manner.
