In the growth of the Internet, various challenges have been encountered. One of those is a battle between censorship and free speech, particularly in the context of material potentially inappropriate to certain audiences. I just brought my site, at least the WordPress-driven part of it, into the modern era of ICRA labeling.
The W3C came up with a technology at the height of this issue called PICS, short for the Platform for Internet Content Selection. In some ways, that technology saved the Internet. If you read Weaving the Web: The Original Design and Ultimate Destiny of the World Wide Web
by Tim Berners-Lee, you will read how there was legislation in progress to restrict the Web. PICS revolved around content providers being able to rate their own content, rating criteria from third parties, and rating decisions by end users. It was a system based on trust that didn’t impose anything on anybody.
As the technologies used to communicate metadata evolved, so did rating bureaus communicating their labels. Originally the Recreational Software Advisory Council for Internet used a system based on PICS. As RSACi morphed into the Internet Content Rating Association, the labeling became more detailed and granular. As ICRA has now morphed into the Family Online Safety Institute, they have moved their labeling to leverage RDF. I learned this when a 404 report for my site was for labels.rdf. I have now created that latest version of the labels for my site and link to it from my WordPress site.
My site is rated as having no nudity, mild language, and user generated content amongs other things. Check for yourself with the label checking tool.
