Digital Directions: The Semantic Web
In addition, adoption of semantic technologies has been slow, since it is built upon other standards—particularly XML and Web Services (a standard way that software can connect with one another on the Internet). It has taken time for XML and Web Services to become widespread. With those standards in place, the semantic approach can and will be increasingly used. However, this will only occur in specific areas of content when there is a particular, usually financial, rationale for doing so.
