The second part of this four-part series shows you how to translate the abstract information model for data in your web pages into one of the three formats supported by Schema.org: RDFa, Microdata, and JSON-LD

Schema.org is an initiative originally created by search engine companies and experts to support web publishers by describing the things that web pages are actually about. This series, in which I explain the Schema.org core information model, helps you expand your web developer skills and get a head start on advances in search engine platforms and personal assistants like Siri, Google Assistant, and Alexa.

The State Government says it's sent a serious threat to the owners of one of Albany's prime vacant lots, by signing off on a plan that would allow it to reclaim the site. But the Opposition maintains it's a hollow threat.

Once the staple of regional travel, motels are facing an increasingly uncertain future as online alternatives bite away at revenue.

Some Broome tourism businesses hope a parliamentary inquiry will lead to a crackdown on accommodation websites, while others say 'the sharing economy' needs support.

It's no secret Tasmanians are proud of their rich convict history, which draws in tourists from far and wide, but there's much more to Van Diemen's Land than the infamous penal settlement at Port Arthur.

Tasmania is brimming with history but anyone who owns a heritage-listed property knows it takes "buckets of money" to keep it up and running. Is it worth it?

Leonora, a small town in the West Australian Goldfields, is being touted as a suitable location for an underground, low and intermediate-level nuclear waste storage facility.

Researchers at the Mediated Matter Group at MIT Media Lab have created Aguahoja, a collection of natural artifacts that were digitally designed and robotically fabricated from the molecular components found in trees, insect exoskeletons, apples and bones.

Uluru, Kakadu and other cultural landscapes may be tourist meccas, but one respected elder says it's a misconception that tourist dollars are going back into Aboriginal communities.

Forty years after the Vietnam War, two Canberra veterans have developed digital maps to help locate some 300,000 Vietnamese war dead still missing in action.

People who use a carriage service such as websites and social media to incite others to break into farms could be sent to jail under new laws passed through Federal Parliament.

Social networking has literally transformed the way the world communicates. What began as entertaining online forums for reconnecting with old friends and former colleagues has also morphed into real-time virtual hotlines for job posters and seekers, political compatriots and natural disaster survivors.

It’s been an odd set of months. I got busy with Drop-In Time and then very un-busy. I’ve been keeping...

How many times has this happened to you when searching online? You find several links to sites that look like they have the information you’re looking for. However when you go to those sites you find only a few ads and nothing but a couple lines of useless text. (If you’re lucky to even find that) So you go back and look around some more and find another link that takes you to another site like exactly like the first one,..............well maybe the color is different. After a bit more searching and running across several more websites like this, you either luck out or find the information you’re looking for, or get pissed off and give up. If this happened to you I don’t need to tell you how frustrating MFA websites are.

If you use some type of analytics to monitor your websites performance you’ve probably seen its bounce rate. So what is bounce rate exactly? It can be defined in a couple of different ways; it can either be an indicator to the number of visitors who view only one page of your site and leave. Or the number of visitors who leave your site after a short amount of time (usually only a couple of seconds)............

When Sam Goree and his colleagues came across articles and blog posts that claim or ask that websites today look very similar to each other, they were intrigued. Unfortunately, since these articles didn’t have an empirical study to back them up, they ran a test to determine whether this claim had any truth to it, and if so, the reason behind it.

We ran a series of data mining studies that scrutinized nearly 200,000 images across 10,000 websites.

And what did they find out? Websites, indeed, were becoming very similar.

More details about this study over at Fast Company.

What are your thoughts about this one?

For the sake of completeness (and also because a visitor requested it), the Layout Wizard has been updated to support one column websites as well. As a result, it can now create one, two and three column websites (depending on which you prefer). The generated web page is mobile-friendly and completely customizable. There are no advertisements, and nothing you enter into the Wizard is recorded anywhere. And it's free.

The feces contain the oldest example of parasite DNA ever recorded.
