Binary resources and containment triples

Hi,

This is regarding how to handle containment triples when creating binary
resources.

As per the current spec (5.2.3.12), upon creating an LDP-NR the servers may
create an LDP-RS to maintain metadata about the newly created LDP-NR and
advertise that using a Link Header. E.g.

HTTP/1.1 201 Created
Location: /image.jpeg
Link: <http://www.w3.org/ns/ldp/Resource>; rel="type"
Link: <http://example.org/metadata>; rel="describedby"

The question is after the creation, which triples should be added to the
container.

(1) Is it only the newly created LDP-NR ?

<ldpc> ldp:contains <image.jpeg>

or

(2) or both LDP-NR and LDP-RS ?

<ldpc> ldp:contains <image.jpeg>
<ldpc> ldp:contains <metadata>

This relevant text in the spec about the containment triple.

[[ 5.2.3.2 When a successful HTTP POST request to a LDPC results in the
creation of a LDPR, a containment triple must be added to the state of the
LDPC whose subject is the LDPC URI, whose predicate is ldp:contains and
whose object is the URI for the newly created document (LDPR). Other
triples may be added as well. The newly created LDPR appears as a contained
resource of the LDPC until the newly created document is deleted or removed
by other methods. ]]
