## Database creation

The knowledge graph of concepts is generated from the information stated in [this Google Spreadsheet](https://docs.google.com/a/vizzuality.com/spreadsheets/d/1awsO5aPEOv_OEFTakIhn-Ej7RFw46UP-jUWXnskPRqk/edit?usp=sharing).

### Step by step guide to import the Graph

1. Download the aforementioned spreadsheet as a CSV file
2. Upload it to the server using scp
3. Copy it to the folder called **import** that is located inside the Neo4j installation
4. Download the JSON file resulting from this request to the WRI API https://api.resourcewatch.org/dataset/?app=rw&includes=vocabulary
5. Execute the JAVA program: [src/main/java/com/vizzuality/CreateDatasetTagCSV.java]
6. Upload the resulting file to the server using scp
7. Copy it to the folder called **import** that is located inside the Neo4j installation
8. Execute the various Cypher statements included in the file: [ImportDBCypher.txt](ImportDBCypher.txt)

> Steps 4-7 can be skipped in the case you're not interested in adding the screenshot of datasets and their tags as a proof of concept

## Examples of queries

### Get all concepts that are descendants of the term 'energy'

```
MATCH (n:CONCEPT)-[*]->(e:CONCEPT {id: 'energy'})
RETURN n,e
```

### Get all datasets tagged with water or any of the descendants of water

```
MATCH (d:DATASET)-[:TAGGED_WITH]->(c:CONCEPT)-[*]->(c2:CONCEPT)
WHERE c.id='water' OR c2.id='water'
RETURN d,c,c2
```
