Rapportive

Rapportive is a plugin for gmail, which trawls the social graph.

I would class it as one of the few applications which makes use of foaf (perhaps more the ideals than the direct execution); but it lets you view someone's connectivity to you on the social web.

FOAF from Freebase

I made a quick FOAF from Freebase application.

Here's mine.

You just pass in an ID and out comes RDF/XML. It's limited to things typed as people.

This will help mend the gap between freebase RDF and common vocabularies, and was pretty easy to do - what other RDF vocabularies exist out there which would be nice to map onto freebase?

Fire eagle

Andrew points to Fireeagle.

It's a geotwitter, basically - applications can read and write information for "where is user X now".

This is the web 2.0 version of menow.

Neat.

A stupid OpenID question

I am only dimly aware of what openid is/how it works.

All of a sudden I've got a livejournal, blogger, and flickr openid. So how would I merge them?

For instance, I log into a foo.com via the livejournal openid to leave a comment. The next time I log in, about 3 months later, its via my blogger openid.

I'm the same person, but how do I tell foo.com that?

The only answer I really have is "OpenID + FOAF", but only livejournal and one or two others bother outputting this.

PEAR is getting foaf...

Finally, PEARweb is getting foaf output - I'll have a reputable foaf file again.

Yay.

Drupal 4.7 and the foaf.module

I wanted the foaf module for drupal on 4.7; so instead of being a whinger; I just went out and did it.

Here's the patch:

Automatic Movie Ratings web service!

FilmTrust is a semantic web research project by Jen Golbeck. It's nifty and finally fills that void in my life where I want to share it all with the blogosphere.

To that end, I've written some very simple and poorly implemented base classes for PHP blogs. All you need is to install PEAR::XML_Serializer and extract some files, then you are off on the road to developing.

For a live demo, see my movies.

Download FilmTrust Webservices Kit.

As ever, the code is under the GPL.

For Non Geek Blogger

Do you want to get movie ratings and reviews on your site or blog? It's really simple!

1. Sign up to FilmTrust and rate some movies.


2. Add some code to your website or blog template.
   

   
   
   <script
   src="http://www.ahsonline.com.au/dod/filmtrust/example.php?
   user=[YourUsernameHere]
   &javascript=true">
   </script>
   
   

   
   

Note: The above Javascript will insert your movies as well as a small Google Adsense advertisement. Ensure that your blog host allows advertising (ie, livejournal does not). I request that you keep the advertising present. You don't have to if you don't want to. But while the code is free providing bandwidth and eating isn't.
