Technorati Tags is great at collecting user based tags from blog posts, when you view a tag like apple you’ll get a mix of computer and food posts.
What if there was a register for all these tags…microformats does something similar.
When you include the tag review in your blog post, you append it according to what the code for review is in the register…this is hReview.
When you use the hReview, you are saying this blog post is a review/summary/critique…you don’t use the hReview if your blog post is about reviewing your homework before you hand it in…just use a simple Technorati Tag like review in these cases…this I believe is the difference…there has been a consensus or agreed use for this special tag.
Let’s just be careful who ever makes these up does it in a group environment, we want these special tags to get it right.
Structured Blogging tries to achieve the same thing, by people having a field in their blog editors.
Now for each of these special tags there is a dedicated search module…check out the hReview tag search engine in the Technorati kitchen…compare it with the tag “review” in Technorati Tags.
In the future for a book review on cats we could mark up a blog post:
All you would have to do is search book in the review engine, and you will get all book reviews about cats…is this right…is the search for the term book a fielded or full-text search?
A service like Edgeio who collects posts with the tag “listing” could really benefit from a hListing tag (this will disambiguate tags)…maybe we can have a glossary for hTags…this way tags have got meaning.
But then Edgeio wouldn’t harvest much content as not everyone is going to use hTags, people are already Technorati Tagging away…it’s here to stay.
I guess microformats or these “h” Type tags are a way to share clean and unpolluted information…can anyone make these up, is all they need a little momentum.
What if people make up similar one’s will we need not only a glossary, but a thesaurus…will the namespace solution not be a cure.
NOTE: I use the word cure because tags are spreading like a virus, the tagspace is uncontainable, it is still a semantic mess.
Check out what microformats is all about.
[ADDED: now I see that Technorati Tags is just a microformat like all these new ones (topic/subject), the problem is that the tags aren’t used only for topic labels, whereas at least hReview is certain it will be describing a review. But what kind of review is it…a restaurant, music, book, film, etc…it seems the hReview has an item type field within it…but is this a free choice like tagging, or a selection (it’s a drop down in the hReview Creator below)
Not sure if I’ve grasped this concept entirely…it looks promising.
Here is a sample Review.
