This research describes an empirical study of how the Dublin Core Metadata Element Set (DCMES) is used by 100 Data Providers (DPs) registered with the Open Archives Initiative (OAI). The research was conducted to determine whether or not the DCMES is used to its full capabilities.
Eighty-two of 100 DPs have metadata records available for analysis. DCMES usage varies by type of DP. The average number of Dublin Core elements per record is eight, with an average of 91,785 Dublin Core elements used per DP. Five of the 15 elements of the DCMES are used 71% of the time. The results show the DCMES is not used to its fullest extent within DPs registered with OAI.

Dublin Core and OAI-PMH Research Questions
As a result of reading about this debate, I decided to analyze DCMES usage by registered OAI-PMH-compliant DPs. My hypothesis is that DCMES is not used to as full an extent as possible by the DPs. My research aims to answer the following questions.
- Which individual elements of the DCMES are used or not used?
- Which individual elements of the DCMES are used the most? Which are used the least?
- Are there different “types” of DPs? If so, does usage of individual elements of the DCMES vary by type?
The answers to these questions are applicable to the debate over whether or not the unqualified DCMES is an appropriate metadata schema for the OAI-PMH.
