Integrate OpenCalais with Adobe CQ5

November 27, 2012

After Thomson Reuters bought ClearForest in 2007, some of its technology became the nifty open source project OpenCalais. The Cognifide blog offers some integration advice in “Adobe CQ5—OpenCalais Integration.”

The OpenCalais Web Service automatically incorporates semantic metadata into content. The best way to see what it does is to past a chunk of text, any text, into their Document Viewer. The tool will tease out and insert links for topics, social tags, entities (like organizations or industry terms), and events & facts. After you’ve played with that, check out the examples of ways the technology has been implemented on the Showcase page. It is acceptable to use the free OpenCalais for commercial purposes (the API key is obtainable here), but a Calais Professional version is available for power users.

Blogger and software engineer Mateusz Kula suggests a way to integrate OpenCalais with the Adobe CQ5 marketing cloud that makes automatic tagging a breeze. He writes:

“A fairly good way to integrate OpenCalais with CQ5 was to create a workflow step for content tagging that could be embedded into any workflow fired on some CQ event or by hand. The mentioned step pulls data internally from a page and calls the OpenCalais integration OSGi service.
Text data is collected from the fields of components lying on a page, then the integration service sends concatenated text to a web service and pulls tags back. Finally the workflow step adds nonexistent tags into the CQ tag manager ‘Calais’ namespace and applies tagging to a page.”

A helpful workflow diagram and configuration tips follow this explanation. Cognifide has created an integration package, which includes an example workflow to get you started. The final paragraph of the article includes a link you can use to download the package’s zipped folder.

Before they were snapped up by Thomson Reuters, ClearForest began in 1998 as an independent software start-up based in Tel Aviv, Israel. Marketing tech consulting firm Cognifide is located in London, UK. They are proud of the partnerships they have formed with Adobe and Sitecore.
