The Neo4j company is encouraging developers to model a domain they know and like in a graph model, creating an interactive GraphGist, which can be hosted on GitHub Gists. To create a GraphGist, one needs to find a great domain, whiteboard a good example graph model, determine interesting use-cases, create Cypher statements for setup and query-use-cases, and compose the content nicely in an asciidoc-graphgist-file. The public GraphGist needs to be registered before September 30, 2013, and participants can win prizes including the honor and a cash award.
