Clustering filter values

Sometimes, you might want to cluster filter values.

These clusters can be set in the clustering/filterOptionValues field in the Settings file (src/app/config/settings.ts).

Example

As an example, in the src/app/config/settings.ts file below, the "Personen" entry checks for each of the node's Type fields (rdf:type, rico:hasRecordSetType, sdo:additionalType, ...) if it refers to any of the clustered values (sdo:Person, pico:PersonObservation, foaf:Agent, ...).

filtering: {  
  filterOptions: {  
    type: {  
      label: 'Soort',  
      fieldIds: ['http://www.w3.org/1999/02/22-rdf-syntax-ns#type',
			     'https://www.ica.org/standards/RiC/ontology#hasRecordSetType',
				 'https://schema.org/additionalType'] 
    },
},
...
clustering: {  
  filterOptionValues: {  
    people: {  
      label: 'Personen',  
      valueIds: ['https://schema.org/Person',
			     'https://data.cbg.nl/pico#PersonObservation',
			     'http://xmlns.com/foaf/0.1/Agent']
    }
  }
