ACAP and Escenic Content Engine

ACAP (Automated Content Access Protocol) is a proposed method of providing machine-readable permissions information for content, or electronic online DRM. As there has been some debate regarding ACAP, Escenic would like to state that Escenic Content Engine supports ACAP for customers wanting to implement it.

ACAP is an extension to the "robots.txt" format, used by search engines to determine which parts of a website should be indexed or "crawled". One example is "ACAP-allow-index: /news/2008/ time-limit=until-2008-12-31", requesting search engines not to index the specified content after December 31 2008.

At the time of writing, only one search engine, French Exalead, has joined ACAP. Google, Yahoo and MSN have not, as can be read in this article at Journalism.co.uk.

Implementing ACAP with Escenic Content Engine

Escenic customers wanting to use ACAP with Escenic Content Engine can do so without any limitations. As ACAP states on their website: "Implementing ACAP should take just 30 minutes at the most. It is an extremely simple process for any IT professional".

Using a "robots.txt" file with Escenic Content Engine has always been possible, and extending it with ACAP statements is straight-forward. More advanced functionality, such as automatic updates of "robots.txt" based on events, and integration with Escenic Content Studio is also possible, using the Escenic Content Engine open Java API.

The Times Online was the first publisher to implement ACAP, using Escenic Content Engine. This is their robots.txt file.
