Some weeks ago, Tantek was introducing a new microformat hReview.
We are pleased to announce the first public draft (v0.1) of hReview, jointly co-authored by representatives from America Online, CommerceNet Labs, Microsoft, Six Apart, Technorati, and Yahoo!. hReview is an open microformat standard for publishing and indexing distributed reviews on the Web. This standard enables users to contribute, identify, and aggregate review content on their own web sites and blogs as well as on community sites.
I didn’t have time yet to dig into it but it is good that they analyzed previous attempts (I was trying to use RVW by Alf Eaton and to keep my list on Allconsuming but I didn’t put too much effort into this) and that they ask for Feedback; almost all the links are to Wikipages so you can edit them directly there.
In general I really appreciate the work of Technorati (I also wrote a paper backing their proposal of VoteLinks, submitted to Web Intelligence 2005: “Page-reRank: using trusted links to re-rank authority” (pdf)).
Some other link I’ll try to digest later on: jluster on hreview, hreview on technorati, hreview on del.icio.us, organizedshopping on hreview, adriancuthbert suggested to use this_is_an_hreview as common tag (tagspace?).
It would be great to have this format widely adopted so that the amount of decentralized published reviews will become soon huge and I will have a large amount a data for what I’m working on in my PhD: Trust-aware decentralized Recommender Systems. If interested, check my (a bit outdated) PhD proposal at my papers page.
