Customer-specified structural metadata, defining the internal contents of the volume, can be entered and produced in XML format.

Elements of structural metadata for books might include general front matter, title page, table of contents, preface, dedication, chapter titles, page numbers, indices, appendices, notes, back matter.

Elements of structural metadata for journals might include table of contents, article titles, article authors, page numbers, and indices.

We can create metadata from Excel spreadsheets, tab- or comma-delimited files.
