9Duplication of Content
● Why ?○ Same information submitted to different repositories○ Harvested from multiple sources
● How can we deal with duplication ?○ Unique identifiers
■ DOI■ Handle.net■ ORCID■ ISNI■ ...
● What happens if no unique identifier is present ?
10
A De-Duplication Service for the Humanities
● Motivationo Huge amount of humanities related content in Europeo Many aggregation projects about cultural heritage
● Simple exampleso Same dataset is aggregated from different sourceso Same dataset is submitted multiple timeso Same author deposits data to different repositorieso Same author registers twiceo Two co-authors submit the same dataset twice from two different locations
11
Why De-Duplication
● Cleaner, more accurate data
● Save time in submission validation
● Save space and resources when aggregating content from multiple
sources
● Improved interoperability
