Which datatype property to reuse for "deleted_at"?

I'm converting some social media data sets to RDF. I try to use only popular ontologies/vocabularies. So far SIOC, FOAF, Dublin Core and SKOS are sufficient. But now I need a datatype property to link a post URI with the date it is deleted (well, marked as deleted in fact). There are dcterms:created and dcterms:modified but nothing about deleted, which I guess is natural - if it is actually deleted there is nothing to link it with. Now I'm considering dcterms:validbut I'm hoping there could be a better option.

I think that some of the DC properties are probably applicable. The documentation for some of them say that they take dates or ranges. If you have a begin and end date, it seems like you can put them together to make a range. E.g,. the documentation for available and date say:

available URI: http://purl.org/dc/terms/available
Label: Date Available
Definition: Date (often a range) that the resource became or will become available.

URI: http://purl.org/dc/terms/date
Label: Date
Definition: A point or period of time associated with an event in the lifecycle of the resource.

There's also a temporal property that might be helpful (but I'm not sure exactly how it's supposed to be used):

Term Name: temporal
URI: http://purl.org/dc/terms/temporal
Label: Temporal Coverage
Definition: Temporal characteristics of the resource.
Type of Term: Property
Refines: http://purl.org/dc/elements/1.1/coverage
Refines: http://purl.org/dc/terms/coverage
Has Range: http://purl.org/dc/terms/PeriodOfTime

That suggests that coverage might be of interest, too, and that you'll want to look at what a PeriodOfTime is.
