SUSHI – What is it?
SUSHI stands for Standardised USage Harvesting Initiative and is a standardised protocol to enable the automated exchange of information. SUSHI was created by NISO (National Information Standards Organization) to be a general standard but with a particular COUNTER extension to facilitate the automated exchange of usage data.
SUSHI – What is the point?
The process of collecting information from multiple publishers can become a laborious task for an institution. While COUNTER has established a standard to simplify the comparison of results, the collection of that data was still a manual process with the authorised representative either having to visit the publisher’s online resource of take the file which had been delivered and combine it with the data from their other subscriptions. Where an institution has potentially dozens of subscriptions, this requires time and effort. SUSHI enables this process and the collation of the results to be automated by ensuring that the payload is consistent between publishers.
SUSHI – What happens?
1) The Subscriber registers with the publisher to receive their COUNTER reporting via SUSHI providing either a specific IP address from where the request will come or confirming the range from which it will come.
2) Publisher provides an ID to the subscriber (this could be the same ID as is currently used to access reports manually or an alternative ID)
3) Subscriber sets up a SUSHI client to collect their information incorporating the ID which the publisher has provided.
4) At the appropriate time once a month, the subscriber's machine launches the SUSHI client which sends its credentials to the publisher's SUSHI module.
5) A machine to machine 'handshake' takes place where the publisher's SUSHI module recognises the ID and the IP address and delivers back to the subscriber's SUSHI client the report data requested in the XML format that has been defined in the protocol.
6) This XML file can then be loaded into the subscribers system and combined with the data from other publishers automatically.
SUSHI and Marketwave HitList
To comply with the COUNTER 3 and 4 requirements, publishers need to be able to make their data available to their customers via machine-to-machine transfer using based on the SUSHI protocol. The SUSHI module extends Marketwave HitList to enable publishers to provide their data in COUNTER compliant XML format via SUSHI
