The purpose of this paper is to understand the role of objects in interactive innovation, i.e. interaction for innovation among core inside innovators, peripheral inside innovators and outside innovators. Going beyond the predominant usage of ‘boundary objects’ we argue that a pluralistic approach of objects is needed to better understand and trace...

1. The integrative research field of biodiversity–ecosystem functioning (BEF) requires close collaboration between researchers from different disciplines working on different scales in time, space as well as taxon resolution.

Improving intellectual property (IP) literacy among small and medium-sized enterprises (SMEs) has lately been discussed as a means for improving IP culture within these companies. Diverse public and private actors have, therefore, developed some tools to improve IP awareness and literacy in small companies. We analysed existing tools, intending to...

In the current technology intensive environment, companies can no longer ignore the need to efficiently manage their IPR (Tonisson & Maicher, 2012). Much of the IPR-related expertise that can help to overcome the barriers related to technology production and commercialization is nowadays offered in digital form. Digital IPR-related services are def...

Ecological research produces a tremendous amount of data, but the diversity in scales and topics covered and the ways in which studies are carried out result in large numbers of small, idiosyncratic data sets using heterogeneous terminologies. Such heterogeneity can be attributed, in part, to a lack of standards for acquiring, organizing and descri...

Intellectual Property issues (IP) is a concern that refrains companies to cooperate in whatever of Open Innovation (OI) processes. Particularly, SME (Small and Medium Enterprises) consider OI as uncertain, risky processes. Despite the opportunities that online OI platforms offer, SMEs have so far failed to embrace them, and proved reluctant to OI....

Semantic technologies like Topic Maps provide a generic way of structured data representation. These technolo-gies can be used to create data stores of any kind. To use them, it is necessary to fill them with data and therefore an editor is needed which provides input masks for the data. In this paper we present an Editor Generator Toolkit that ena...

The usage of XTM without a Topic Maps engine is cumbersome becaus...

If Topic Maps should be exchanged in distributed environments a common semantic problem occurs: Do two Topics refer to the same Subject?
