      1 # External namespaces and terms
      2 
      3 Most applications using VF will need terms defined in various other vocabularies.  In fact, some of these are essential to the complete ValueFlows model. Below are the essential elements we are reusing from well established vocabularies (web ontologies).
      4 
      5 ## SKOS
      6 
      7 https://www.w3.org/TR/skos-reference/
      8 
      9 * [`skos:note`](https://www.w3.org/TR/skos-reference/#note)
     10 
     11 ## FOAF
     12 
     13 http://xmlns.com/foaf/spec/
     14 
     15 * [`foaf:Agent`](http://xmlns.com/foaf/spec/#term_Agent)
     16 * [`foaf:Person`](http://xmlns.com/foaf/spec/#term_Person)
     17 
     18 ## ORG
     19 
     20 https://www.w3.org/TR/vocab-org/
     21 
     22 * [`org:Organization`](https://www.w3.org/TR/vocab-org/#org:Organization)
     23 
     24 ## OM2
     25 
     26 http://www.ontology-of-units-of-measure.org/resource/om-2/
     27 
     28 * [`om2:Measure`](http://www.ontology-of-units-of-measure.org/resource/om-2/Measure)
     29 * [`om2:hasUnit`](http://www.ontology-of-units-of-measure.org/resource/om-2/hasUnit)
     30 * [`om2:hasNumericalValue`](http://www.ontology-of-units-of-measure.org/resource/om-2/hasNumericalValue)
     31 
     32 
     33 * [`om2:Unit`](http://www.ontology-of-units-of-measure.org/resource/om-2/Unit)
     34     * A list of units can also be found here.  Each subclass on this page has an additional list of units.
     35     * VF will use (at least) `rdfs:label` and `om2:symbol` as properties of Units.
     36     * See note at the end of [Flows](/introduction/flows.md) regarding display of unit `om2:one`.

     54 * [`time:intervalDuring`](https://www.w3.org/TR/owl-time/#time:intervalDuring)
     55 
     56 `vf` defines property chain axioms for `vf:hasBeginning` , `vf:hasEnd`, and `vf:hasPointInTime` as slight variant
     57 of [Alignment of PROV-O with OWL-Time](https://www.w3.org/TR/owl-time/#time-prov).
