With more than 9 million users and 21 million repositories, Github is the world's biggest code sharing platform. Its API offers a window to the public activity of about 600,000 events a day. In this talk, Christophe will present how he transformed this activity into a graph and mapped the network flow between users, communities, programming languages, and code repositories. He will demonstrate how to gain new insights by building interest graphs and recommendation engines on top of this valuable data

Graphgen aims at helping people prototyping a graph database, by providing a visual tool that ease the generation of nodes and relationships with a Cypher DSL.

Many people struggle with not only creating a good graph model of their domain but also with creating sensible example data to test hypotheses or use-cases.

Graphgen aims at helping people with no time but a good enough understanding of their domain model, by providing a visual dsl for data model generation which borrows heavily on Neo4j Cypher graph query language.

The ascii art allows even non-technical users to write and read model descriptions/configurations as concise as plain english but formal enough to be parseable. The underlying generator combines the DSL inputs (structure, cardinalities and amount-ranges) and combines them with a comprehensive fake data generation library to create real-world-like datasets of medium/arbitrary size and complexity.

The genrated data can be visualized, directly imported into a remote Neo4j database or exported in a variety of formats.

Users can create their own models combining the basic building blocks of the dsl and share their data-descriptions with others with a simple link.
