DAI in DARE
• DARE: Digital Academic REpositories
–
–
–
–
Universities + KNAW + NWO + KB
Infrastructure for linking the IR
Stimulate production of digital scientific output
2003 – 2006
• 2007 – 2010: SURFshare
2
Main issues in DAI
• Unique identifying number for researchers / authors
• National scale
• Benefits:
– Improve searching for electronic publications
– Integrate searching for electronic and nonelectronic publications
– Link Library (Catalogue) and research environment
(Metis)
3
Two projects
• Pilot in 2005 – 2006
– one university: Groningen
• Roll-out 2006 - 2007
– 13 academic research organizations
• Project leader: Anneloes Degenaar
• DAI website at University of Groningen:
– http://dai.weblog.ub.rug.nl/
– http://dai-uitrol.ub.rug.nl/

Authors with the same name
Use of one or more initials
Changing names
Spelling variants
Diacritics
Pseudonymes
Name in religion
Nicknames
Collective names
Different structure of names in other languages and cultures
…..
• Discussions on standardization and unification started in the
Netherlands in the Orion project (2003-2004)
15
Proposed solution
• Need established
• “External”Requirements:
– use existing mechanisms
– local management
– national function
• Solution: use “collocation” mechanism of libraries and
Metis as source

How did we link
• Mechanisms
– Initial load per organization
– Online input buttons (webtemplates)
– XML output
– Synchronization mechanisms
• Requirements
– No overwrite of library data!
– Deduplication (Matching/merging)
19
Datamodel developed
• Datamodel copied from bibliographic model: three
levels
• Metis name-information added to library data; no
overwrite
• Affiliations and other fields added

Metis makes list of names
Format conversion
Load DAI in Metis
Match names with
auth file
Manual dedup of list
Merge names with
names found
Dedup in Metis
Load new names
(not found)
Load B-records
(? Duplicates?)

Data enrichment in Metis

Conversion to cataloguing system
Matching
Merging: merge / new / B-record
• Results depend on quality metadata
– 95 % automatic / 5% manual
– 70% automatic/ 30 % manual.
– 50 % automatic / 50 % manual
27
Online process
• DAI-button in Metis to create DAI-number
• Export DAI-button in NTA/Cataloguingsystem to Metis
• DAI-button in IR to create DAI-number
• Separate DAI-http-request for online input
• Online input via current cataloguing tool
• + Offline synchronization mechanisms between Metis
and NTA

Results of the DAI project
• Now:
–
–
–
–
50% of the researchers have a DAI
Procedure for initial load in place
Start with online procedure
P rivacy statement
• Autumn 2007
– Online procedure in place
– Procedure for synchronization in place
– 100% of the researchers will have a DAI in 2007 (ca. 40.000)
32
Things to do
• Finalize the roll-out, develop services (passport …)
and implement a usergroup
• Add DAI in metadatastandards (DCX, MODS)
• International standardisation: ISPI
• Involve authors for controll and updating
