Hosting Linked Data using PURL.org

I was wondering what the community thought about using http://purl.org to
actually host Linked Data. I know using PURL is common for hosting
*vocabularies*, but what about actual data?

PURL provides what they call "partial-redirects" [1] which allow you to use
URIs such as http://purl.org/foo/<number> and be able to accordingly
redirect to your Linked Data resource.

It seems logical to me that also data, apart from vocabularies, should pass
the test of time, and using PURL is a way to help that. Are there any
best-practices regarding this?

Thank you,
Luca
