The diagrams below represents the structure of an ONIX Main Series and Subseries records, showing the Group structures. These Group structures are not actual data elements or composites, but are convenient means of grouping composite and data elements that must occur together in an product record. In technical XML terms, these structures are represented in the DTD by “parameter entities”. The Group numbers correspond exactly with the section numbers under which the descriptions of data elements are grouped in the Main Series and Subseries Guides.

Note that the structure of the composite elements are not shown in detail below and can be found in Product record Groups as follows: SeriesIdentifier – see PR.5; Title – see PR.7; Contributor – see PR.8; OtherText – see PR.15; Publisher – see PR.19.

The diagrams displayed on these pages have been created using XML Authority™, a DTD and Schema editing and visualizing tool from TIBCO Software Inc.
