Technorati tag service and COREBlog

Technorati has released today a very interesting service. They've developed a tag based search application based on Flickr tags, del.icio.us tags and blog post's categories.

Two examples with tags google or basque

As for Coreblog, a little hack by Erral, that I post here with his permission:

COREBlog doesn't give info about our posts' categories in RDF files, so we need to change some lines of code in 2 files to show our posts in that service.

Let's go to change them ;)

Open rdf10_xml via ZMI:

Find this line:

  ...  <dc:subject />
 ... 

Delete it and put these lines:

   ...   <dtml-in entry_category_list>     <dc:subject><dtml-var name></dc:subject>   </dtml-in>
  ... 

Save it!

Now, the second step: open rdf91_xml via ZMI:

Find this line (it's the 3rd one):

  ...  <rss version="0.91">  ... 

And change it:

  ...  <rss version="0.91" xmlns:dc="http://purl.org/dc/elements/1.1/">  ... 

Then find these lines:

  <dtml-in "rev_day_entry_items(count=top_days)">  <item>
   <title><dtml-var title></title>    <link><dtml-var blogurl>/<dtml-var id></link>   </item>   </dtml-in>
  

And change them:

  <dtml-in "rev_day_entry_items(count=top_days)">  <item>   <title><dtml-var title></title>   <link><dtml-var blogurl>/<dtml-var id></link>
  <dtml-in entry_category_list>     <dc:subject><dtml-var name></dc:subject>    </dtml-in>   </item>   </dtml-in>
  

Save it!

Now, we've to configure our COREBlog to ping Technorati each time we publish a post. Go to "Settings" tab, and add http://rpc.technorati.com/rpc/ping at "PING Servers".

This actually works. Erral's blog is in Basque and Spanish and his spanish category/tags already show at Technorati as with ajedrez and varios
