Danny Palmer of Computing.co.uk reports, “US President Barack Obama has signed an executive order that requires government agencies to make publicly accessible data open and machine readable. ‘Government information shall be managed as an asset throughout its life cycle to promote interoperability and openness, and, wherever possible and legally permissible, to ensure that data are released to the public in ways that make the data easy to find, accessible, and usable,’ reads the Open Data Policy order. In 2009, Obama pledged to make his administration the most open in the history of US government. The administration hopes that innovators, including researchers and entrepreneurs, will be able to examine and use the data to benefit the country.” Read more

Benjamin J. Balter recently opined that WordPress needs to start better expressing content in a machine readable format. Balter begins with an explanation of REST: “The idea is simple: a URL should uniquely identify the underlying data it represents. If I have a URL, I shouldn’t need anything else to view or otherwise manipulate the information behind it. WordPress, for the most part, does this well.

The problem is, however, in WordPress’s sense, it points to the display of that content, not the content itself. Read more

Jim Hendler and Theresa A. Pardo have created a primer on machine readability for online documents on Data.gov. The pair explain, “Historically, efforts to make government information available to the public have focused on pushing static information about government programs and services to the web. The intended user has been a human who can read, print, and take actions based on reading the material or by engaging in a form-based transaction. In some cases, users were able to query the data or map the results using sophisticated geospatial displays. Access to the data itself, on the other hand, was rarely provided.” Read more

A recent article informs online retailers that “Starting now, you’re going to need good structured markup on your X/HTML in addition to your white hat tactics. I see structured markup as being equally important to authoritative inbound links as a ranking factor when optimizing content. Why? Because search robots are designed to serve search engine users by matching their search query expectations, known as user intent. These bots are machines, and they’re trying to discern the human mind’s evaluation of information in answer to human-entered keywords.” Read more
