The Optique platform is a solution that integrates several modules developed by the different expert groups of each university using the Information Workbench – semantic integration platform – developed by fluid Operations AG, also member of the project.

The Northstream demonstrator is a specific setup of the Optique platform, including a set of scenarios related to the domain of manufacturing of products. It also comes with a training database, corresponding ontologies and mappings and a stream engine, which together enables users to get hands-on experience without the need to cope with a tedious setup, technical barriers or security restrictions.

The Northstream demonstrator is pre-packaged as an app on top of the Information Workbench. While the database itself is not big in size, it satisfies the purpose of demonstrating the main concepts and functionalities of Optique. Optionally, external data sources can be connected, however, security constraints are often a major obstacle to overcome. Please contact us if you are interested in installing it otherwise than locally.

The Postgres database and the Stream generator connections are already pre-defined within the platform via the data source connector. Furthermore, the demonstrator is shipped with pre-installed “ready-to-run” configuration artefacts, for example, mappings and ontologies.
