"""Fetches the JSON for Project 60

Shows just the relationships block, rather than the full JSON, as this is what we are interested in here.

Relationships are grouped by type. Each relationship has a '*data*' block, which provides an array of relationship resource.

Each resource is described with an '*id*' and '*type*'.

SEEK supports Restful Routes, each resource can be identified by:

    https://<host>/<resource-type>/<id>
    
so,  *{'id': '18', 'type': 'institutions'}* would be https://fairdomhub.org/institutions/18

**Note** that only visible resources are listed, any related items that are not visible due to sharing permissions, are omitted. (more in accessing as an authorized user later).
