In general, yes; but if you wish to register for ICRAchecked, and your site is accessible with and without the www prefix to your domain, then no, you must use an absolute URL in the link tag’s href attribute. Why? Filters and the ICRA label tester will follow a relative URL in your link tag, […]

Most ISPs take the security of their customers’ websites very seriously and take a number of precautionary measures. One of these can be to only allow certain types of file to be uploaded to their servers – and that list may not include files ending with .rdf. The simplest way around this is to use […]
Some servers, particularly Microsoft servers, will allow you to upload the labels.rdf file but will not “serve it back to you” even if you put its correct URL in your browser. You might get a not found message (the famous “Error 404”) or a message saying “You are not authorized to access this site” which […]
We have heard of rare cases where web sites that are protected by firewalls become unavailable after labels have been added. The reason is that the labels.rdf file is declared as being an RDF file. However, the firewall examines the file as it passes through and detects that it is an XML file. Both are […]
Families using tools such as Internet Explorer’s Content Advisor will continue to benefit from PICS labels for some time. If you have obtained a new (RDF) label since January 2006, then you will have received a PICS version of your label along with your Link tag. You can therefore remove your old v02 PICS tag, […]
Introduction The ICRA system is designed to allow providers to label their content quickly, efficiently and flexibly. In order to ensure predictable results for users, the way in which different filters process labels must be consistent. The recommended processing rules are set out below to enable content providers to assess the most convenient method of […]
ICRA labels are held in a special file, usually called labels.rdf. This file is effectively broken down into sections to provide filters and other clients with the information they need. The best way to explain this is by examining the (fictitious) example below. Section 1 <?xml version=”1.0″?> <rdf:RDF xmlns:rdf=”http://www.w3.org/1999/02/22-rdf-syntax-ns#” xmlns:rdfs=”http://www.w3.org/2000/01/rdf-schema#” xmlns:label=”http://www.w3.org/2004/12/q/contentlabel#” xmlns:dc=”http://purl.org/dc/elements/1.1/” xmlns:icra=”https://icra.org/rdfs/vocabularyv03#”> Section 2 […]
ICRA labels are written using the Resource Description Framework (RDF). This is the key technology behind the “Semantic Web.” [1] “The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” Tim Berners-Lee, James Hendler, Ora Lassila,The Semantic Web, Scientific American, […]

Within a labels file, the actual ICRA label is encoded in a block similar to this: <label:ContentLabel rdf:ID=”label_1″> <rdfs:label>No nudity, no sex, no violence, no potentially offensive language, no user-generated content, no other potentially harmful activities</rdfs:label> <icra:cz>1</icra:cz> <icra:lz>1</icra:lz> <icra:nz>1</icra:nz> <icra:oz>1</icra:oz> <icra:sz>1</icra:sz> <icra:vz>1</icra:vz> </label:ContentLabel> This shows a label declaring “None of the above” in all the […]
