Current database schema

Database creation

The knowledge graph of concepts is generated from the information stated in this Google Spreadsheet.

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

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

Whole graph

MATCH p=()-[]-() return p
