Structural metadata provides information about how research objects are organized, both within a research object (for example, a book composed of chapters, chapters composed of pages, and pages arranged in a particular order), and relationships between research objects (for example, a preprint, version of record, and a dataset). Learn more about version control, corrections, and retractions.
Within a nested structure, you may find DOIs at different levels. For example, a book chapter may have its own DOI, as may the book it belongs to. Likewise, a journal may have a DOI at the level of title, sometimes volume and issue, and article. A nested structure may also apply to conference proceedings.
