Collection of Useful Datasets to be Imported and Used with Neo4j

How to provide a Dataset Example

1. find a dataset that’s relevant and interesting and not too huge (around 10M nodes/rels max) so it’s feasible to import quickly for a user

2. describe the dataset in a few sentences

3. explain where it originates from and perhaps the original format

4. provide a schema picture for the target graph model

5. provide steps to get the source files and where to put them e.g. into import directory (if loading from the original URL is not feasible)

6. explain necessary neo4j config changes (e.g. setting min/max heap to 2G or setting page-cache to 2-4G depdending on the dataset)

7. provide load scripts for load csv. with necessary indexes / constraints created upfront

   • explain any non-obvious transformations or conversions

8. provide 3-5 use-case queries on the imported dataset, add explanations and pictures as needed

9. put all that content into an asciidoc file (formatting help here: )

10. put that file into a directory of this github repository (pull request: https://github.com/neo4j-examples/neo4j-example-graph-datasets)

11. have someone review that PR and help you generate a browser guide (for https://guides.neo4j.com/datasets/your-dataset ) and optionally a GraphGist

12. If all is good your dataset can be included in http://neo4j.com/developer/example-data

How to create a Browser-Guide/GraphGist

You create a Guide by creating a file in AsciiDoc syntax.

This section shows the basics of using AsciiDoc syntax and a few additions for custom Browser Guides.

Please write one sentence per line, up to the punctuation mark, that makes it much easier to diff the changes.

Define a Cypher query

[source,cypher]
----
CREATE (n{name:'cypher'})-[r:LIKES]->({name:'icecream'}) return n.name, r
----

becomes:

CREATE (n{name:'cypher'})-[r:LIKES]->({name:'icecream'}) return n.name, r

Those queries become clickable areas in a Browser Guide that the user can run.

If they have multi-statement mode enabled in Neo4j browser, you can add multiple statements separated by semicolon ; at the end of line. That’s especially useful for creating indexes/constraints etc.

Monospaced block: indent lines with one space.

Tables are well supported.
