Setup of reference networks

Trezorix develops solutions that enable clients to connect all kinds of digital resources, existing and newly created, through their metadata, in a findability layer called the RNA environment. RNA stands for Reference Network Architecture. The metadata, as well as content itself, can be processed and managed with a set of versatile, easy-to-use tools: the RNA Toolset.

Data modelling

Modelling of data is at the heart of an RNA environment. Key to the event- and statement-based modelling system is its flexibility. Basic modelling is designed in a way that suits the general needs of our clients. The flexibility of the model is achieved through the possibilities to extend and detail it to specific user needs. This can be done in two ways:

By preconfigured modelling: in this case we analyze the client's legacy data to configure the model so that his content fits comfortably into it, with ample flexibility for future demands.

By modelling on the fly: in this case the client can extend the model to his own needs while working in the findability layer. Because the model is event- and statement-based, it enables clients to define their own events, statements, roles and relations to enrich their content and to achieve efficient findability.

Use of existing data  

Getting datasets and content into the findability layer can be done in different ways. The method being applied depends on the nature and origin of the data.

For some datasets it is sufficient to use a once-only conversion. In such a process a set of data is copied and transferred into the findability layer where it can be managed and edited further. This process is for instance supported by the table import tool, which is part of the RNA Toolset. With this tool clients can add record-like data to MS Excel templates and upload these to the RNA environment.

Other datasets benefit more from periodical updates to, or a live-connection with the RNA environment. The Dutch Species Register for instance, a highly dynamic dataset containing records and content on more than forty thousand species that live in the Netherlands, used for several years a periodical update mechanism to regularly add the latest information on Dutch species to the online environment. Currently an RNA environment houses all the data, where updating is done directly with the RNA Toolset.

When the exchange of data from a dataset with outside applications is based on standard protocols, such a protocol can be used for the exchange of data with the RNA environment. There are for instance OAI PMH and Biocase connectors available for this kind of data exchange. The RNA Toolset offers several mapping functionalities that can be used to connect import from legacy databases to existing metadata in the findability layer.
