GraphGist Homework Assignment

Domain and Data

Take a domain that you are really interested in, be it politics, beer, music, arts, cooking, sports, travel, software, organizations.

Draw a model of the domain on a whiteboard or digitally, add a few example entities (nodes) you know and their relationships. Think about at least 3 questions you want to answer using this connected data. Remember to add all the information you need to answer those questions.

You should end up with at least 15 nodes and 20 relationships.

GraphGist Format

Now go to https://portal.graphgist.org/about and learn about the GraphGist documentation format (which is basically AsciiDoc a text-markup language with a few embellishments).

You can either start from the template that is provided there or a blank plain text file.

You can also explore the other GraphGists on the portal for further inspiration.

Setup

Add a snappy title for your demo and some prose that describes the domain and the types of its entities and their relationships.

Now add an image link, e.g. to the drawing you created earlier.

Now you can start creating your domain with Cypher, Neo4j’s query language in a Setup section. Follow the syntax example in the template or on the portal page.

Render the resulting graph with the //graph marker.

Show all friends of John

Then take your questions from before and put each of them in a titled section (e.g. == Show all friends of John) add some prose.

Add the Cypher statement in a [source,cypher] codeblock.

MATCH (me:Person {name:"John"})-[:KNOWS]-(friend)
RETURN friend, me.name

Render the results either as //table or //graph_result.

Submission & Grading

While you’re working and when you are done, you can use the "Preview" functionality of the GraphGist portal to render your document in your browser. Go to https://portal.graphgist.org/submit_graphgist add the public URL of your file, your title and click Preview.

When done, either hand in the preview link or submit your link to the portal and share the resulting link with your lecturer.

The grading will be on completeness, correct usage of Cypher, good prose and educational quality of your queries (i.e. at least 2 of the 3 should use relationships or paths).
