GoodRelations Amazon Checker Google Chrome Extension

During the past weeks I have been busy with a pure JavaScript implementation of the RDFa API (the specification is currently in draft status). RDFa is a way to embed semantic data into websites. This allows for adding e.g. the information that the number 5.99 actually is a price of an item with a certain name "item x". If you have never heard of RDFa, you can read the RDFa Primer document published by the W3C. In order to semantically mark-up information, a so-called ontology or vocabulary is necessary. For products or offerings that you can order via the Internet a common ontology is GoodRelations by Martin Hepp (@mfhepp). For retailers this is quite interesting as their product data might be interlinked and featured by search engines (see Martin Hepp's presentations for a bigger picture). In my recent Chrome extensions spree I have coded yet another very simple Chrome extension called GoodRelations Amazon Checker that allows for checking whether a GoodRelations-marked-up product from a website is available on Amazon.
