The blog post by Kimchi Taco, “Metadata: Not Just for Humans but Computers Too. Enter Semantic Web,” included a link to a how-to article on the semantic web by Tracy Wilson. This article written in clear, easy-to-understand language helped clarify what is meant by the semantic web.
At the heart of the semantic web is the term “semantic,” or, meaning. Semantic web refers to mark-up with meaning. This type of mark-up doesn’t just create information for computers to transfer and display information, but indicates what the information means. XML even allows the creator to name the tag for greater specificity of meaning. Controlled vocabularies—also called schemas or ontologies—limit the vocabulary in order to help computers understand. While the World Wide Web can be the Wild Wild West of information, the W3C provides guidelines and protocols for the semantic web.
The semantic web takes the contributions of information management utilized by libraries long before the internet and weds it with the vast possibilities of the Web.
