"72% of respondents to the online survey either agreed or strongly agreed that a significant problem for link resolvers is the generation of incomplete or inaccurate OpenURLs by databases (for example, A&I products)."

Defining methodology for addressing problem…
Recently, researchers have indicated the need for metadata quality metrics , including:
conformance to expectations;
logical consistency and coherence.

Problem: Too often links sent from Aph did not successfully resolve to requested resource.
Objective: Examine quality of OpenURLs offered to users by Aph in order to improve the linking.
Aph Study investigated:
Faulty citation metadata from source database.
Method to evaluate the OpenURLs.

Concept of scoring in Aph study (based on B. Hughes study)*
establish a baseline for comparison;
results to be shared with data providers;
develop a best practice.
Problem analysis in Aph study limited to:
presence/absence of citation metadata elements
OpenURL quality model: compares elements in Aph OpenURLs to those of other providers.
No scoring was achieved for Aph , but model is first step towards scoring system.
