Hypertext Markup Language (HTML) and Portable Document Format (PDF) are presentation formats: they describe documents which usually only need to be read and not changed or edited. This might seem rather strange for a file format, but corresponds to the age-old publishing model: a newspaper reader does not usually need to be able to alter the contents of his favorite paper. Publishing, the distribution of information to a small or large circle of readers is, for the most part, a one-way street. This does not exclude the possibility of interactive applications and the collaborative creation or editing of documents, but the operator of a Web site, not its readers or users, is the one responsible for its contents.
