A production system is expected to be composed of readily available resources, which have clear interfaces. In ODIN, Tampere University is developing and modelling resources as resource descriptions (RDs), which are a digital representation of real, physical production resources in association to the three industrial use cases. Developed resource descriptions include robots, grippers, sensors and other relevant components.
For each different resource, a resource description file is created and published by the resource provider. This description represents the basic characteristics, interfaces and properties of the resource. It can contain links to documentation, CAD models and to illustrative figures. One part of it, is also the capability descriptions which are coming from a centrally shared capability model.
The resource description files can then be saved to a catalogue, from where the potential users and various tools can utilize them. For example, resource descriptions can be searched, inspected, and distributed. This resource description catalogue is a public storage and provides a web service with RESTful API for application integration and is currently under development.

As practical use, a system designer can call the capability matchmaking service and provides two inputs for the matchmaking - product description and a search space. The search space can be the existing system layout or pool of resources selected from the resource description catalogue. The capability matchmaking software will then process these inputs and provide the matchmaking result to the designer. The result includes information about the resources and resource combinations matching for each process step of the product requirement. The matchmaking result can then be imported into the Visual Component’s simulation environment and used as starting point for new system design.
A total of 34 different resources have been identified, to be modelled in ODIN with resource descriptions: 7 for the aeronautics use case, 13 for the automotive use case and 9 for the white goods use case.
