DATA FORMATS
Choice of software format for digital data:
• planned data analyses
• software availability
• hardware used –e.g. audio 
• Discipline-specific standards and customs
Digital data = software dependent
Digital data endangered by obsolescence of software/ hardware
Best formats for long-term preservation -standard formats, 
interchangeable formats, open formats
e.g. tab-delimited, comma-delimited (CSV), ASCII, RTF, 
PDF/A, OpenDocumentformat, SPSS portable, XML

DATA FORMAT CONVERSIONS
Convert data for preservation or back-up: export, save as
Beware of conversion errors losses:
• loss of internal metadata
e.g. convert MS Access to tab-delimited tables
• loss of editing, formatting, formulae
e.g. convert MS Word to RTF
• truncation or loss of data 
e.g. string variables lost in SPSS –STATA conversion; MS 
Access memo fields truncated in conversion to CSV
Check for errors and changes after conversion
Example:  MS Excel to tab-delimited

VERSION CONTROL
Keep track of different copies or versions of data files
Which method:
• single site vs. across locations
• single vs. multiple users
• different versions to be stored vs. files to be synchronised
Good practice:
• unique identifiers for files (file names)
• record file status/versions
• record relationships between files
e.g. data file and documentation; similar data files
• keep track of file locations
e.g. laptop vs. PC

VERSION CONTROL
Single user of data files:
• file naming –unique file names with date or version number 
(avoid spaces!)
e.g. FoodInterview_1_draft; FoodInterview_1_final; 
HealthTest_06-04- 2008; BGHSurveyProcedures_00_04
• version control table or file history within or alongside data 
file
• version control facility within software
e.g. MS Windows software
