From what I read on Twitter, it seems there's a bit of confusion regarding SMOB. Indeed, while SMOB provides a framework for Open and Semantic Microblogging, it does not define a new protocol, but simply uses SPARQL/Update over HTTP to exchange information between hubs (posting / removing notices and following / followers). Hence, this is not something that competes against OMB, the OpenMicroBlogging specification.

Actually, OMB is something we planned to look at for a long time, as briefly discussed when Status.net / OMB was presented in the W3C Social Web XG telco. I've finally took the time to analyse the full spec and checked how it compares with the distributed microblogging implementation of SMOB, and more generally with the vision of Semantic Web / Linked Data (SW/LD) microblogging services.

So here is a proposal for "Semantic OMB" (on Status.net wiki) that describes how the current OMB protocol fits with the previous idea. In particular, it aligns the terminology with existing classes / properties from well-known ontologies, and discusses how some current parts of the spec should be updated. It also discuss how OMB operations can be mapped to SPARQL/Update queries, based on the ones that currently happen in SMOB for cross-hubs synchronisation.

As you can see when browsing it, besides the terminology mappings, most of the things are compliant and there are only a few things that shall be discussed, in order to:

• enable a better "distributed-ness" by keeping profiles owned by their users and not necessarily creating remote accounts;
• making some mandatory elements being optional, as they are contained in the data that is exchange between services thanks to the Linked Data principles.

Thanks to these small updates, it could provide a protocol enabling SW/LD systems to be designed based on the OMB protocol, while having a sufficient abstraction level to comply with OMB systems using other technologies for data modeling and exchange. I'd be more than happy to see such features in an upcoming OMB release, and hopefully see deeper links between OMB and SW/LD efforts, as both aims to achieve the same goal of openness and interoperability. Comments and feedback are welcome on the related thread on the OMB mailing-list.

Here's a new release of SMOB, the Semantic MicrOBlogging framework. This release includes various new features, the main one being the integration of Twitter messages in SMOB so that you can use your SMOB hub as a Twitter client, where each Tweet is represented in RDFa using SIOC, FOAF, etc.

In addition, the new release provides:

• RSS feed for hub owner's messages;
• Automatic @reply when replying to a Twitter message (including sioc:addressed_to annotation);
• Updated user-interface for #tags mappings, now done using tabs to avoid too much scrolling;
• Ability to directly check @reply messages;
• Starring system using the Review vocabulary.

SMOB v2.1 can be downloaded here. If you used a previous version, you will also need to apply this patch after the update. It may remove some of your following / followers (as there have been some changes in the related RDF data - this should be taken into account by the patch, but who knows ...), in that case you'll add to add them again, sorry for the inconvenience !

Hopefully, a 2.2 release will be out in the next weeks, including geolocation of messages, advanced browsing features and other funky improvements. Feature requests can also be suggested on its dedicated bugtracker.

Any status update posted to Twitter from a SMOB client now features a 'from SMOB' link, a good way for semwebbers to promote it.

A v0.1 release is planned soon, but if you already want to use it, just get the latest svn version.This one also features the firsts steps of RDFa integration in the client homepage, as you can see

As John Breslin already detailed last week, we (Tuukka Hastrup, Uldis Bojars, John and myself) recently work on SMOB, a semantic microblogging architecture, that will be presented at next SFSW workshop,

There's a lot of ways to update your Twitter status / browse friends without going on their website (which is sometimes really slow !). You can also simply use curl in bash.
