  1. Noark 5 validator

  2. Summary • Noark 5 extraction format • Noark 5 extraction validator • Demo • Issues with the Noark 5 extraction format • Future steps

  3. N5 extraction

  4. N5 extraction – contd.

  5. N5 extraction – arkivstruktur.xml

  6. N5 extraction – arkivstruktur.xml

  7. N5 extraction – endringslogg.xml

  8. N5 extraction – arkivuttrekk.xml

  9. N5 extraction – arkivuttrekk.xml

  10. Validating N5 extractions • Verify vs Validate • Does validation depend on the system? • Validation tool • Noark 5 v3 • 10 validations currently • Plug-in oriented • Extend with new features • Jhove • Pdfinfo • LibTIFF • 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? • Export user registry • Import a Noark 5 extraction • Data quality
