I'm confident that DCAT supports this already. The DCAT definition does 
not say whether the collection of data is in a single file or multiple 
files since a dcat:Dataset is an abstract concept that may be accessible 
by a distribution.

dcterms:hasPart and dcterms:isPartOf are probably useful here, and I'd 
want to use those at the Dataset level, not the distribution level, 
something like:

<readings-2014-11-08T00:00> a dcat:Dataset;
   dcterms:isPartOf <readings-2014-11-08> .

<readings-2014-11-08T06:00> a dcat:Dataset;
   dcterms:isPartOf <readings-2014-11-08> .

<readings-2014-11-08T12:00> a dcat:Dataset;
   dcterms:isPartOf <readings-2014-11-08> .

<readings-2014-11-08T18:00> a dcat:Dataset;
   dcterms:isPartOf <readings-2014-11-08> .


<readings-2014-11-08> a dcat:Dataset;
   dcterms:hasPart <readings-2014-11-08T00:00>;
   dcterms:hasPart <readings-2014-11-08T06:00>;
   dcterms:hasPart <readings-2014-11-08T12:00>;
   dcterms:hasPart <readings-2014-11-08T18:00>;
   dcat:distribution <readings-2014-11-08.zip> .

<readings-2014-11-08.zip> a dcat:Distribution;
   dcat:mediaType "application/zip" .


The 4 timed readings and the collected readings for the day are all 
dcat:Datasets, i.e. they are all "A collection of data, published or 
curated by a single agent, and available for access or download in one 
or more formats."

Would that work for you Laufer?
