We prepare the content so that it can easily be found on SpringerLink, Google, etc. and can be used for various outputs (e.g., conversion to HTML for Internet publication or into a typesetting system for printing). This means that the manuscript data is enriched with additional information (tags) that go beyond the pure contents of the text. For example, the tagging of the metadata such as author name(s), affiliations, or the chapter title ensures that all relevant data is available as required. The tagging of the reference list entries enables us to crosslink the cited references with the original publication.
