Current HistoricalArchive Situation
• Publications date to 1886
• For many publications – 1 copy exists
• Many publications irreplaceable – no disaster recovery
14 September 2006 / UN Dissemination
3
Relevance to BLS
• Unique historical archives – 120 years of publications
– 10 years systematically available online
• User expectations are rising
• Standards are evolving
• Mandates are under discussion

4
Meeting Emerging Standards
• File Format– Adobe Acrobat PDF/A
• Labeling – Adobe’s Extensible Metadata Platform (XMP)
• Metadata Schema– Data Documentation Initiative (DDI)

Archive on Bureau’s Website
• www.bls.gov
• Servers inside and outside firewall
• Public domain
• Accessible thru BLS Home Page

Choosing Metadata Elements
• Schema Choice– DDI Subset
• Schema Useful?– Dissemination and Preservation– Perform user studies – 2 phases
• Phase 1 -- Initial studies (3)– What users want / need– Relatively open-ended, exploratory
• Phase 2 -- Focused studies (2)– Expose users to DDI subset– Obtain feedback

Reasons for DDI
• Want success @ BLS
• Minimize capture burden
• Unknowable metadata– Old documents (back to 1886)– DDI allows level of granularity
• Conformance– Easy with DDI

Potential Problem
• Dissemination and Preservation?
• Is DDI suitable for preservation?
• Preservation elements
• Looking at other standards

User Studies--Overview
• Adopt techniques of– focus groups– group interviews
• Recruited members of general public– Screened for familiarity w/ Gov’t Stats
• Five groups, 2-6 members per group– 3 groups -- initial, exploratory– 2 groups – review DDI elements

User Studies Results
• Initial exploratory groups (3)– Descriptors consistently identified
• title, date, and geographic coverage• Descriptors essential and informative
– Members – generalize in abstract - hard• Difficulty imagining other descriptors• If personal need does not exist a priori, then
– “What can I do with this information?”– “How is it useful to me?”

User Studies Results
• DDI-focused groups (2)– Descriptors verified
• Keywords also very important• However, very large sets of keywords
– Counterproductive or Confusing– “TMI” – information overload

User Studies Results
• DDI-focused groups (2)– Some want title or subtitle to answer
• “How is this report useful to me?”• “How can I put it to use?”• Example – Title includes “A guide”
– More useful than the formal title/name
– Criterion for acquiring a document• Action, use of information• Not subject matter
