Statistical Report

Nova uses Standardized Usage Statistics Harvesting Initiative (SUSHI) protocol which is dedicated to work with Counting Online Usage of Networked Electronic Resources (COUNTER) to provide access to various kinds of usage reports which includes Journal, Database, Platform and Book reports for improved analysis.  



COUNTER developed a standard named Code of Practice to count the usage of electronic resources such as journals, databases, books, reference works, and multimedia and to ensure the statistics are agreeable. This international standard enables librarians and publishers to procure reliable and accurate statistical information. COUNTER has published various Code of Practice releases to build up a standard for producing online publication usage reports  in a precise manner.

COUNTER serves librarians, vendors, intermediaries and others by facilitating the recording and exchange of online usage statistics. The COUNTER Code of Practice Release 4 provides guidance on data elements to be measured, definitions of these data elements, output report content and format, as well as on data processing and auditing. To have their usage statistics and reports designated COUNTER compliant, vendors must provide usage statistics that conform to the Code of Practice.”

SUSHI Schema

The SUSHI protocol with core XML schema (XSD), ReportRequest, ReportResponse and a Web Services Description Language (WSDL) that are needed to be put together to create a SUSHI Web service.

“The SUSHI standard has three supporting XML schemas posted on the NISO website. The core schema (sushi[version].xsd) can be used with any conforming usage statistics reports. The two schemas with “sushi” in their name are basically retrieval envelopes for the XML-formatted COUNTER reports. The COUNTER XML schemas can be used separately from SUSHI by anyone who wants the reports in XML formats.” – NISO
