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
