SUSHI is a standard for harvesting electronic resource usage data that was recently updated. The SUSHI committee released an updated version of the SUSHI standard and COUNTER schema to include new report types and attributes. They also published a technical report on SUSHI-Lite, a lightweight approach using HTTP/REST and JSON to deliver usage data snippets or full reports. Going forward, the committee aims to promote the SUSHI registry, collaborate on standards, and support developers through documentation and lists.

2. Overview
• What is SUSHI
• Who is on the committee
• What’s new
• What we are working on
• Future

3. SUSHI…
WHAT IT IS ...
• An ANSI/NISO Standard (Z39.93)
• Defines automated request and response model for
harvesting e-resource usage data
• Designed to work with COUNTER, the most frequently
retrieved usage reports
WHY YOU SHOULD USE IT …
• It replaces the time-consuming user-mediated
collection of usage data reports
• The protocol is generalized and extensible, meaning it
can be used to retrieve a variety of usage reports

6. SUSHI standard updated
Z39.93-2014 released in September…
SUSHI version 1.7 introduces new Filters
and Report Attributes

7. SUSHI standard updated
New Filters and Report Attributes
• Allows for more precise specification of report
requests, e.g.
– Filter results to return usage only for a specific department
– Ask to have zero usage excluded from the report
• Backwards compatible
• The new elements are optional
• Current implementations of SUSHI for COUNTER R4
should NOT be affected

8. COUNTER schema updated
COUNTER schema 4.1…
• Expanded to support new COUNTER “Article” reports
• Backward compatible
– New elements are optional
– Standard COUNTER reports (JR1, BR1, BR2, etc.) did not
change since they do not use the new elements

9. COUNTER SUSHI Implementation Profile
Updated
Minor update to address some issues
• PubYr attribute value to represent “unknown” should
be “0001” and not “0000”
• Fixed COUNTER report names in tables for
consistency
• Updated schema versions as necessary to match
current standard

11. SUSHI-Lite
A technical report – not a new standard
• A Light-weight approach to delivering SUSHI reports
• Using up-to-date web service approaches that uses
HTTP/REST for communication and JSON for the
contents
• Ideal for delivering snippets of usage but also useful
for full reports

12. SUSHI-Lite
Sample use cases…
• Serials management system pulling use for a
particular journal for in-workflow usage display

13. SUSHI-Lite
Sample use cases…
• Serials management system pulling use for a
particular journal for in-workflow usage display

14. SUSHI-Lite
Sample use cases…
• Institutional repository exchanging article-level usage
with publisher
• Usage Factor: Journal processing organizations
pulling article level usage from institutional
repositories and other content sites

15. SUSHI-Lite
Sample use cases…
• Alternative metrics system retrieving article-level
usage from publishers, institutional repositories and
other content sites for…
– Presenting overall impact numbers
– Offering real-time access to stats

16. SUSHI-Lite
Live example …
https://www.jusp.mimas.ac.uk/api/sushilite/v1/Report/?Rep
ort=JR1
&RequestorID=test
&CustomerID=test
&ItemIdentifier=journal:issn:1084-5453
&BeginDate=2012-01
&EndDate=2012-06
*based on an early prototype -- syntax and response doesn’t exactly match final
recommendations

17. SUSHI-Lite

18. SUSHI-Lite
Proof-of-concept implementations…
• JUSP (Journal Usage Statistics Portal)
– Supply journal level COUNTER usage statistics
– Contributed by: Paul Needham, Cranfield
University

19. SUSHI-Lite
Proof-of-concept implementations…
• IRUS-UK (a JISC-funded repository service)
– For consolidating article-level COUNTER usage
statistics from multiple repositories
– Paul Needham, Cranfield University

20. SUSHI-Lite
Proof-of-concept implementations…
• Open Journal System (OJS)
– Supply COUNTER JR1 reports
– Exchange article-level usage with alternative
metrics organizations
– Contributed by: Clinton Graham & Brian Gregg,
University of Pittsburg
