Collaborating on complex XML data structures is a non-trivial task in domains such as the public sector, healthcare or engineering. Specifically, providing scalable XML content dissemination services in a selective and secure fashion is a challenging task. This paper proposes a publish/subscribe infrastructure to disseminate enterprise XML content utilizing document semantics. Our approach relies on the dissemination of XML documents based on their content, as described by concepts that form the basis for an interoperable description of XML documents. This infrastructure leverages our earlier parsing  scheme for efficient processing of enterprise XML and at the same time for protecting the integrity and confidentiality of XML content during dissemination.
