cluster sets of related terms in a list?

[pvgenuchten]

In the soil domain, terms are typically grouped in clusters (or code lists). Examples of clusters from the benchmarks glossary are:

• ECOSYSTEM SERVICES
• SOIL FUNCTIONS
• SOIL INDICATORS (or soil property or parameter)
• MANAGEMENT PRACTICES
• LAND USES

What options do we have to cluster terms using the skos ontology

• Via a broader/narrower relation
• Via a conceptscheme relation
• Via a collection relation

One of the use cases for clustering is a set of filters next to a catalog search result, clustered by topic

@pvgenuchten Has this Soil Health BENCHMARKS glossary been RDFed? Or do they have plans to RDF them? If not, is there value in converting them to RDF triples under SKOS schema?
