What to do if there are validation errors?

11. Validation 1
Validate all XML files against their XSD schemas

12. Validation 2
Validate checksums and file format of all documents referenced in arkivstruktur.xml

13. Validation 3
Validate the number of documents referenced in arkivstruktur.xml against the «antallDokumentfiler» value in arkivuttrekk.xml

14. Validation 4
Validate that the number of documents referenced in arkivstruktur.xml is GTEQ to the actual number of files in the «dokumenter» directory

15. Validation 5
Validate the number of «mappe» elements in arkivstruktur.xml against the «mappe numberOfOccurrences» value in arkivuttrekk.xml

16. Validation 6
Validate the number of «registrering» elements in arkivstruktur.xml against the «registrering numberOfOccurrences» value in arkivuttrekk.xml

17. Validation 7
Validate the checksums of all files (XML and XSD) referenced in arkivuttrekk.xml

18. Validation 8
Validate the entries in endringslogg.xml against the objects in arkivstruktur.xml

19. Validation 9
Validate the checksum of arkivuttrekk.xml

20. Validation 10
Validate the custom metadata in arkivstruktur.xml against a schema (custom_metadata.xsd)

21. N5 extraction format – issues and possibilities
References to documents
Initial object revisions
DocumentObject does not have a systemID
Can all objects have custom metadata?
