Requires a `json2bracket.py` conversion script by Thomas from
https://frosch.cosy.sbg.ac.at/thuetter/json-datasets. Currently included with
this repository. Better, enable getting it directly from Thomas's repo.
Download the latest version of an entity in JSON format (Q40 is Austria).
Current revision as of 09.04.2020 is `1153700198`.
```
wget https://www.wikidata.org/wiki/Special:EntityData/Q40.json
```
Download a specific revision of an entity to file `Q40_1151291349.json`.
```
wget https://www.wikidata.org/wiki/Special:EntityData/Q40.json?revision=1151291349 -O Q40_1151291349.json
```
To download and convert all data files, execute
