I'd say LOS (excusing the acronym - I was living in Austria ;) is also about applying REST to Linked Data. For instance with services that manage an ontology as a mutable, versioned resource, or a query as a resource that can be applied to a graph by RESTful interaction (something I've also recently seen Talis do under the name 'SPARQL stored procedures').
Although the origins are certainly different I think REST makes the interweaving of content and metadata much more natural and one immediately hits it when thinking about RDF-based versions of useful APIs (thinking of the common examples of Flickr and Slideshare). This is even the case with MusicBrainz as, although the primary content is not there you have derived resources like acoustic fingerprints. I'd be really interested in looking at combining from the principles of the approaches, exactly what we're trying to achieve at linkedservices.org, especially since you've ideas also on rel links and authentication (which we're experimenting with, but are not ready yet to fix principles for).

Linked Open Services indeed seems very related technology-wise, but it seems to have a different motivation: while our goal is that of managing and updating Linked Data and treat content and metadata uniformly and applying REST to Linked Data, Linked Open Services is about linking services and applying Linked Data to REST. Or am I confused here? Maybe it would be worthwhile to combine both approaches, we will look into it. :-) Am 05.05.2011 um 11:08 schrieb Barry Norton: > > Sebastian, Michael, can I also point out Linked Open Services [1] as related > work. > > This approach also tries to bring together the full uniform interface of REST > with Linked Data principles, and provides one answer to Michael's question > about the role of SPARQL in common with other approaches, such as Linked Data > Services [2], which are coming together as Linked Services [3]. > > I'm particularly excited about Sebastian's media-oriented approach as I've > been working for just over a month now with MusicBrainz, on the LinkedBrainz > project at Queen Mary's, trying to push these aims - some people might > remember Paul Groth's challenge to the Linked Open Service presentation at > the Future Internet Symposium that MusicBrainz "used to have such an RDF API > and deprecated it". > > Just one more plug: following the success of the ISWC Linked Open Service > tutorial, there will be two Linked Service tutorials at ESWC - one at the > conference and one at the Summer School. > > Barry > > [1] linkedopenservices.org/blog > [2] openlids.org > [3] linkedservices.org > > > Greetings, Sebastian -- | Dr. Sebastian Schaffert [email protected] | Salzburg Research Forschungsgesellschaft http://www.salzburgresearch.at | Head of Knowledge and Media Technologies Group +43 662 2288 423 | Jakob-Haringer Strasse 5/II | A-5020 Salzburg
