https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#h5_ldpc-post-createbinlinkmetahdr
5.2.3.12 Upon successful creation of an LDP-NR (HTTP status code of 201-Created and URI indicated by Location response header), LDP servers may create an associated LDP-RS to contain data about the newly created LDP-NR. If a LDP server creates this associated LDP-RS, it must indicate its location in the response by adding a HTTP Link header with a context URI identifying the newly created LDP-NR (instead of the effective request URI), a link relation value of describedby, and a target URI identifying the associated LDP-RS resource [RFC5988].
