Building a Database-Backed Clojure Web Application
From the webpage:
This article will explore creating a database-backed Clojure web application and deploying it to the Heroku Cedar stack.
The app we’ll be building is called Shouter, a small Twitter clone that lets users enter in “shouts” which are stored in a PostgreSQL database and displayed on the front page of the app. You can see an example of the finished Shouter deployed to Heroku or view the finished source.
See Heroku to sign up for its cloud application platform.
I started to tease the DevCenter about the article Building a Facebook Application since Google is attempting to do the same thing. 😉
The I found that the article covers, however briefly, the Graph API and Open Graph Protocol, which makes it of more than passing interest for topic map applications.
