When managing multi-valued properties in this way, is ordering implied by
order in the document? For example in UML Models of operations, the order
of parameters of an operation is important.

Inserting new values in a specific position would naturally require the
entire document to be PUT back, with the new property inserted in the
correct place. Or perhaps some other more elaborate mechanism could be
invented to allow the insertion or deletion of specific values.

This design adopts the design for multi-valued properties documented in the
CM spec. I don't think this is a good design and we shouldn't propagate it.
The OSLC estimation workgroup is doing this the "right" way, as shown in
this example:

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
 xmlns:dc=".http://purl.org/dc/elements/1.1/"
 xmlns:ems="http://open-services.net/software-metrics/">
 <ems:Project
    rdf:about="http://braintwistors.example.com/ems/v1.0/Project/4201">
    <dc:title>Tsunami 1.0</dc:title>
    <dc:description>
       The goal of ...
    </dc:description>
    ...
    <ems:hasEstimate
       rdf:resource="http://braintwistors.example.com/ems/v1.0/Estmate/4203
" />
    <ems:hasEstimate
       rdf:resource="http://braintwistors.example.com/ems/v1.0/Estmate/4204
" />
    ...
    <!-- other properties of this project resource have been omitted for
brevity -->
 </ems:Project>
</rdf:RDF>

In other words, a multi-valued property is just what it says - a property
with multiple values, as illustrated here by "ems:hasEstimate". You do not
introduce a separate collection resource with separate link resources -
that design is not in the spirit of REST, it's just an old-fashioned OO
programming API exposed via http.

The OSLC Quality Management V1 specification is available at :
http://open-services.net/bin/view/Main/QmSpecificationV1

I would like to thank the Quality Management workgroup members (BigLever,
IBM, Sogeti, and Tieto) for their participation in the workgroup and
contributions to the specification.  The broader OSLC community is invited
to view the specification and provide any feedback in the wiki or via the
oslc-qm at open-services.net mailing list.  The Quality Management V2
specification effort is expected to get underway soon so any feedback on
the V1 specification will be especially valuable.

Best wishes.
