Technorati plugin

Dave Sifry has opened up a Technorati interface that allows outside developers to use the Technorati data. I’ve whipped up a quick MT plugin that can get the Technorati link Cosmos for your entire blog or a specific entry and insert it into your blog pages.

Tim Appnel has taken over the maintenance and support of this plugin as of Oct 2004.

Requirements

• Movable Type 2.21 or greater.
• XML::Simple
  The plugin will check to see if this is installed. Any version newer than 1.0 should work, but the plugin has only been tested using v1.08. You can get the module here, or directly from CPAN. Copy the XML directory into your Movable Type extlib directory.
• XML::Parser
  This is required by XML::Simple. If you don’t already have this installed, your hosting provider will have to do it for you.
• File::Spec
  Movable Type needs this to run, so you already have it. Don’t worry about it.
• LWP::UserAgent
  You can run mt-check.cgi to see if you have this. If you need it, follow the Movable Type installation instructions

Suggested

• MTPlugins::Expressions
  My Expressions plugin is optional and is only needed if you want to use MT tags in your attributes.

Download

Technorati 1.1

Installation

Unzip the Technorati zip file to a directory on your computer.

Configuration

Open the file called technorati.config. You can set common configuration options in this file.

• Key (required)
  In order to use the Technorati plugin, you’ll need to get an API key from Technorati. Without it, the plugin can’t get any information from Technorati. Find the line that starts with “Key” and change the portion that reads XXXXXXXXXXXX to your developer’s token.

• CacheDir (optional)
  By default, Technorati looks for a directory called cache in your MT directory. If you would like to have the cache directory located somewhere else, uncomment the line that starts with CacheDir and change it to match your preferences.

• NoCache (optional)
  If for some reason you don’t want to use the caching features of Technorati, uncomment this line and caching won’t be used. This is not recommended, as it will increase the rebuild times for your pages, but if you are unable to create a writeable cache directory, you can disable caching.

• Parser (optional)
  You probably don’t need to set this, but if you get XML parsing errors mentioning ASCII encoding, uncomment this line in the config file. Advanced users can specify their own parser instead of XML::Parser if desired.

• Debug (optional)
  If you are having trouble with the plugin, uncomment this line. Messages will be shown to you during rebuild that tell you whether or not the cache is being used, the Technorati API URL being used by the plugin, and some other information.

Upload

Open your FTP program and navigate to the directory where you have Movable Type (MT) installed.

Upload the MTPlugins directory to MT’s extlib directory in ASCII mode.

Upload technorati.pl in ASCII mode to MT’s plugins directory. If you don’t have a directory called plugins, create one inside your MT directory.

Upload technorati.config in ASCII mode to your MT directory. This file should be in the same place your mt.cfg is.

Create your cache directory. Unless you changed the location in the config file, you should create a directory called cache inside your MT directory. Set the permissions on this directory to 666. (Tip: On some hosts, you may need to set the directory permissions to 777. Try using 666 first and if you get errors about writing to a file, then use 777.)

The cache directory is where the cache files are stored. You may find that this directory ends up with a large number of files in it. If this concerns you, all of the files in the cache directory can be periodically deleted without causing any harm. Technorati will recreate any cache files it needs.

Usage

Oonce you’ve installed the Technorati plugin, you�ll have a set of new Movable Type tags. Use these in your templates to display information about who’s linking to you.

Available tags.

MTTechnorati
A container tag that defines what information you want to retreive from Technorati. MTTechnorati is a smart tag. What it does depends upon the context where it is used. If you use the tag inside an entry, the tag will retreive a list of incoming links to that entry. If you use it outside an entry, the tag will create a list of blogs that link to your blog, a reverse blogroll of sorts. If you want to override this behavior, you can add some attributes to the tag and tell it what URL you would like to retreive Technorati data for.

This container can have the following attributes:

• url If you define the url attribute, the smart behavior of Technorati is turned off. Instead of getting the links for the blog or for the entry, the plugin will get the links for the URL you specify.
• mode You can choose to get the Technorati link cosmos for the weblog or a specfic permalink. If you don’t specify the url attribute, the mode is set automatically, but you can override it if you want. If you do set a url, the mode defaults to the cosmos for the weblog. Valid values here are weblog and link.
• lastn This tells the plugin how many links you want to get back. The plugin will retreive all the links up to the maximum you define. The default is 10.

MTTechnoratiLinkTitle
A tag representing the title of the blog or page that is linking to you. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkURL
The URL of the blog that is linking to you. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkRSS
The RSS feed for the blog that is linking to you, if it is known by Technorati. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkInbound
The number of inbound links to the blog that is linking to you. This is not the number of links to you, but rather the number of links to them.

MTTechnoratiLinkBlogs
The number of blogs linking to the blog that is linking to you. Like MTTechnoratiLinkInbound, this is not the number of blogs linking to you. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkPermalink
Technorati’s best guess as to the permalink URL for the blog entry that is linking to you. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkExcerpt
An excert from the page that is linking to you. This will be blank for reverse-blogroll searches. It supports an if_blank attribute that specifies alternate text to display if the tag is empty. The attribute can contain MT Expressions.

MTTechnoratiLinkCreated
The date that Technorati first became aware of the link. This will be blank for reverse-blogroll searches. You can use MT’s date tag formatting to format this the way you would like.

MTTechnoratiVersion
The version number of the Technorati plugin.

MTTechnoratiCacheDateTime
The date and time that the plugin cache was last created. The date and time when the cache was last updated. If the cache is new, the current date and time are returned. You can use MT’s date tag formatting to format this the way you would like.

1.0 - Jul 24, 2003

• (Change) Default parser is now XML::Parser on all systems
• (Fix) Parser preferences are sometimes ignored
• (New) If Technorati service doesn’t respond, the plugin doesn’t interrupt the build
