1995Background, why? how?
• A need
• Few $
• No developer resources, little experience
the tool
the tool
DROIDXML
JHOVEXML
NLNZXML
Filter Script
custom XSLT
“XML” file
splitter script
individual PREMIS “Object” XML files
the XSLT
• matches on the file paths of scanned objects• makes use of (in particular):
– the file format info from all tools– the checksums from JHOVE– file extension from NLNZ– environment info from NLNZ– PID and format registry info from DROID
problems/issues
1. limited by the harvesters
2. creates ‘object’ (not ‘PREMIS’) records
3. no GUI (cumbersome)
4. may not be scalable
uses / benefits
• actually useful / implement in your repository
• adopt the mappings from the tool outputs
• simpler than “Fits” and produces PREMIS XML
• illustrates the power of XML
• The tool fulfils a particular need
• Tools like this are relatively simple to create
• XML is powerful and simple
