Cluster

SKOS concept in the PKM Vocabulary.

Notes and artifacts assembled around a single subject, where each member is a part of the whole rather than one more instance of a kind.

Scope note

Three kinds of cluster narrow from here: TimeCluster, EffortCluster and TopicCluster. The period clusters — DayCluster, WeekCluster, MonthCluster, QuarterCluster and YearCluster — sit under TimeCluster rather than directly under this concept.

Broader

• Knowledge — partitive (ISO 25964)

Narrower

• Effort Cluster
• Time Cluster
• Topic Cluster

This term in RDF

• URI — https://w3id.org/pkm/vocab/Cluster (pkmv:Cluster)
• Turtle — terms/Cluster.ttl
• Whole vocabulary — pkm-vocab.ttl

That URI serves this page to a browser and RDF to a client that asks for it, so one link works for both:

curl -L -H 'Accept: text/turtle' https://w3id.org/pkm/vocab/Cluster
