Sashimi

Sashimi is a fake SUSHI provider and COUNTER 5 generator. It acts as a server exposing a very limited but useful part of the SUSHI API.

You can use Sashimi to generate random data to test your SUSHI client. This is how we use at Big Dig Data - as a source of data for Celus online demo.

Installation

Sashimi is written in JavaScript to run under Node.js. Therefore you need to install Node.js (we recommend version 12.16 or above).

Before running Sashimi for the first time, you need to install the required packages by running:

npm install

inside the Sashimi directory.

Usage

You can start Sashimi using the following command from the Sashimi directory:

npm run start

Sashimi will start to listen on a local address using the port 3000. If the port is not available, an error message will be shown.

After Sashimi starts, you can use the address http://localhost:3000/reports/tr to get sample SUSHI report. You can use the following arguments to influence the generated data:

begin_date

The standard SUSHI begin_date argument. If not given, a default value will be used

end_date

The standard SUSHI end_date argument. Defaults to begin_date

requestor_id

The standard SUSHI requestor_id argument.

customer_id

The standard SUSHI customer_id argument.

You can also use the http://localhost:3000/reports/dr endpoint to get a fake Database report. The URL attributes to use are the same as for the TR report.

Features

• uses real journal and database names when generating reports
• data are pseudo-randomly generated - data are random, but the same input always results in the same output
• mimics the usually observed distribution of hits where a few journals/databases have high interest and others not so much

Limitations

• only supports TR and DR master reports
• does not support YOP
• data are not internally consistent - e.g. you can have more Requests than Investigations, which should not happen in the real world
• customer_id and requestor_id are not used for authentication - the system will happily generate data for anybody :)

Bugs and suggestions

We publish Sashimi in the hope that it could be helpful to someone somewhere someday. We do not intend to extend the software outside the scope we need it for.

If you find any bugs, we would be happy if you let us know - preferably on Github, ideally in the form of a pull request. If you would like to have a feature added, you can try contacting us as well, but we do not guarantee anything.
