The software is designed to collect metrics from various sources and is divided into different sections, with the most prominent being the Metrics-drivers-wrapper which contains the packages called ‘drivers’. 

The upload is split into two sections: 

• Altmetrics Registration: This software may be useful to people who have set up an Identifier Translation Service in order to run any of the usage metrics drivers documented in https://metrics.operas-eu.org/docs/getting-started.
• Identifier Translation Service: The Identifier Translation Service is a JSON REST API to a database of publication URIs. The translation service maps works (publications) to URIs (e.g. info:doi:10.11647/obp.0001, urn:isbn:9781906924010, https://www.openbookpublishers.com/product/3) to allow converting from one identifier to another.
