COUNTER-compliant usage statistics were a great leap forward for standardizing the collection of usage data. However, regular collection of data across every COUNTER-compliant package licensed by libraries creates a heavy workload, and was a time-consuming process. This problem of retrieval was the bottleneck that prevented wider use and interpretation of COUNTER reports, and the need to import usage statistics efficiently into a central repository for easier management became increasingly apparent.
The Standardized Usage Statistics Harvesting Initiative (SUSHI) Protocol standard defines an automated request and response model for the harvesting of electronic resource usage (COUNTER) data utilizing a Web services framework. It is intended to replace the time-consuming user-mediated collection of usage data reports.Essentially, SUSHI is COUNTER usage reports, delivered in XML format.
