| # imdb-tsv |
|
|
| Trimmed IMDb TSV snapshots, packaged for direct load into the graph schema |
| defined in `schema.cypher` (Kùzu-style `CREATE NODE TABLE` / `CREATE REL TABLE`). |
|
|
| ## Source |
|
|
| Downloaded on 2026-07-07 from the official IMDb dataset mirror: |
| <https://datasets.imdbws.com/> |
|
|
| The three source files used were: |
|
|
| - `name.basics.tsv.gz` → `name.basics.trimmed.csv.zst` |
| - `title.basics.tsv.gz` → `title.basics.trimmed.csv.zst` |
| - `title.principals.tsv.gz` → `title.principals.trimmed.csv.zst` |
|
|
| ## Processing |
|
|
| The official IMDb TSVs are tab-separated and contain extra columns beyond |
| what `schema.cypher` declares. Each source file was **lightly processed** |
| (header kept, columns projected to the ones the schema references, |
| field names renamed to match the Cypher property names) and recompressed |
| with `zstd` (`.zst`). No row filtering, no value rewriting — the row |
| counts and order match the upstream dump. |
|
|
| | File | Rows (incl. header) | Source columns kept | |
| | ----------------------------- | -------------------: | -------------------------------------------- | |
| | `name.basics.trimmed.csv.zst` | 15,468,443 | `nconst`, `primaryName`, `birthYear`, `deathYear` | |
| | `title.basics.trimmed.csv.zst`| 12,623,654 | `tconst`, `primaryTitle`, `startYear`, `runtimeMinutes` | |
| | `title.principals.trimmed.csv.zst` | 100,343,239 | `nconst`, `tconst` | |
|
|
| Column renames applied during trimming: |
|
|
| - `name.basics`: `nconst → nconst`, `primaryName → primaryName`, `birthYear → birthYear`, `deathYear → deathYear` (no rename; just dropped `primaryProfession`, `knownForTitles`) |
| - `title.basics`: `tconst → movieId`, `primaryTitle → title`, `startYear → year`, `runtimeMinutes → durationMins` (dropped `titleType`, `originalTitle`, `isAdult`, `endYear`, `genres`) |
| - `title.principals`: kept `nconst`, `tconst` (dropped `ordering`, `category`, `job`, `characters`) |
|
|
| The result is the minimal subset needed to materialize the `Actor`, `Movie` |
| and `ActedIn` graph from `schema.cypher` via the COPY statements in |
| `copy.cypher`. |
|
|
| ## Loading |
|
|
| Decompress the `.zst` files (e.g. with `zstd -d`) and then run |
| `copy.cypher` against a database whose schema has been created from |
| `schema.cypher`: |
|
|
| ```bash |
| zstd -d *.zst |
| # create schema from schema.cypher, then: |
| # run copy.cypher |
| ``` |
