What is the purpose of "rel" links?

The Link header in HTTP as used by Riak is defined by RFC 5988. In the Link Relation Type registry (http://tools.ietf.org/html/rfc5988#section-6.2.2) you can see that the relation type "up" refers to a parent document in a hierarchy of documents. In Riak, this means the bucket a key is in.
These are not Riak's own links, but rather an additional use of the Link header form which may be useful to some clients.
I hope that this helps.
