Schema Design
Designed for linking Based on:
Extensive review of actual citations Publisher input
Only essential fields are required Deposit Header Container metadata (journal name, book title, etc.) Publication date DOI, URI
Schema vs. DTD
W3C XML Schema Data validation Parsers
Conformant Xerces 2.0
Semi-conformant XML Spy Turbo XML (XML Authority) 2.2.1.100 or later
0.3 vs. 2.0 Comparison
More Hierarchy Less redundant data
Naming Conventions Preserved 0.3 DTD names where appropriate Used ONIX names for some new elements See documentation for mapping tables
