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 ?

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
