Sarah Mei recently wrote a blog post describing how she and her colleagues modeled a collection of TV shows and a social network. A few of us at Neo felt strongly that these domains were very graphy in nature.

We wanted to see if our intuition was right (we love the Diaspora project and extend our help to you) and so with the help of Cypher, created a mini version of each of the domains that Sarah described.

This is the first of two GraphGists that are part of the response to Sarah’s blog post. If you would like to quickly jump to the second one that details the social networking data model, you can find it here: Social Network Graph Diaspora example

All info for a show

For a particular TV show, show all the seasons and all the episodes and all the reviews and all the cast members from that show i.e. all of the information connected to that TV show.

MATCH (tvShow:TVShow)-[:HAS_SEASON]->(season)-[:HAS_EPISODE]->(episode)
WHERE = "How I Met Your Mother"
RETURN season, episode
Loading table...

We could also grab the reviews if there are any by slightly tweaking the query:

MATCH (tvShow:TVShow)-[:HAS_SEASON]->(season)-[:HAS_EPISODE]->(episode)
WHERE = "How I Met Your Mother"
WITH season, episode
OPTIONAL MATCH (episode)-[:HAS_REVIEW]->(review)
RETURN season, episode, review
Loading table...

Chronological listing of all episodes

Sarah’s next query was:

Display a chronological listing of all of the episodes of all the different shows that an actor had ever been in.

First let’s add another TV show that Josh Radnor appeared in:

CREATE (er:TVShow {name: "ER"})
CREATE (er_s9:Season {name: "ER S7"})
CREATE (er_s9_e17:Episode {name: "Peter's Progress"})
CREATE (tedMosby:Character {name: "The Advocate "})

CREATE UNIQUE (er_s9)-[:HAS_EPISODE]->(er_s9_e17)

WITH er_s9_e17

MATCH (actor:Actor), (episode:Episode)
WHERE = "Josh Radnor" AND = "Peter's Progress"
WITH actor, episode

CREATE (keith {name: "Keith"})

And now we’ll create a query to find the shows that he’s appeared in:

MATCH (actor:Actor)-[:PLAYED_CHARACTER]->(character)<-[:FEATURED_CHARACTER]-(episode)
WHERE = "Josh Radnor"
Loading table...

We could then easily add in more seasons, episodes and reviews if we wanted to.
