... and this example is where the set of files are actually representations of _parts of_ the dataset:

1. First, just using dct:relation
```
dap:atnf-P366-2003SEPT
  rdf:type dcat:Dataset ;
  dcterms:accessRights [
      rdf:type dcterms:RightsStatement ;
      rdfs:comment "The metadata and files (if any) are available to the public." ;
    ] ;
  dcterms:bibliographicCitation "Burgay, M; McLaughlin, M; Kramer, M; Lyne, A; Joshi, B; Pearce, G; D'Amico, N; Possenti, A; Manchester, R; Camilo, F (2017): Parkes observations for project P366 semester 2003SEPT. v1. CSIRO. Data Collection. https://doi.org/10.4225/08/598dc08d07bb7" ;
  dcterms:description "Parkes multibeam high-latitude pulsar survey" ;
  dcterms:identifier "<https://doi.org/10.4225/08/598dc08d07bb7>" ;
  dcterms:identifier "<ivo://au.csiro.atnf/P366-2003SEPT>" ;
  dcterms:license <https://creativecommons.org/licenses/by/4.0/> ;
  dcterms:modified "2017-07-30T08:55:55Z"^^xsd:dateTime ;
  dcterms:relation [
      dcterms:identifier "PH0090_0011.sf" ;
    ] ;
  dcterms:relation [
      dcterms:identifier "PH0090_0021.sf" ;
    ] ;
  dcterms:relation [
      dcterms:identifier "PH0090_0031.sf" ;
    ] ;
  dcterms:rights [
      rdf:type dcterms:RightsStatement ;
      rdfs:comment "All Rights (including copyright) CSIRO 2017." ;
    ] ;
  dcterms:temporal [
      rdf:type dcterms:PeriodOfTime ;
      rdf:type time:ProperInterval ;
      time:hasBeginning [
          rdf:type time:Instant ;
          time:inXSDDate "2003-09-01"^^xsd:date ;
        ] ;
      time:hasEnd [
          rdf:type time:Instant ;
          time:inXSDDate "2003-12-31"^^xsd:date ;
        ] ;
    ] ;
  dcterms:title "Parkes observations for project P366 semester 2003SEPT" ;
  dcat:contactPoint [
      rdf:type v:Individual ;
      v:fn "Marta Burgay" ;
      v:hasEmail <mailto:burgay@oa-cagliari.inaf.it> ;
    ] ;
  dcat:keyword "pulsar" ;
  dcat:landingPage <https://doi.org/10.4225/08/598dc08d07bb7> ;
  dcat:theme <http://registry.it.csiro.au/def/keyword/anzsrc/astronomical-and-space-sciences-not-elsewhere-classified> ;
.
```

2. And using more precise semantics
```

dap:atnf-P366-2003SEPT_1
  rdf:type dcat:Dataset ;

  dcterms:description "Parkes multibeam high-latitude pulsar survey" ;
  dcterms:hasPart [
