A demonstration of simple API composition with RxJava. The API composes upon the BBC's Linked Data Platform APIs to return information about the 5 most used tag concepts for the current day, along with a summary of the latest 5 creative works for each.

To run natively:

• Java 7
• Groovy

To run in a vagrant virtual machine:

• VirtualBox
• Vagrant

To access the Linked Data Platform APIs you'll need to have configured your certificate and the BBC truststore in JAVA_OPTS:

-Djavax.net.ssl.trustStore=certificates/jssecacerts
-Djavax.net.ssl.keyStore=/path/to/cert.p12
-Djavax.net.ssl.keyStorePassword=yourpassword
-Djavax.net.ssl.keyStoreType=PKCS12

If you're running on the Reith network from within the BBC you'll additionally need to have configured the proxy details:

-Dhttp.proxyHost=www-cache.reith.bbc.co.uk
-Dhttp.proxyPort=80

Assuming the above steps have been done, you can run the application. The first time you do this groovy will download the necessary dependencies (so be patient, it may take a little while).
