However, due to a multitude of proprietary document formats with rather simple link models, today's possibilities for creating hyper-links between snippets of information in different document formats are limited. In previous work, we have presented a dynamically extensible cross-document link service overcoming the limitations of the simple link models supported by most existing document formats. Based on a plug-in mechanism, our link service enables the linking across different document types. In this paper, we assess the extensibility of our link service by integrating some document formats as well as third-party document viewers. We illustrate the flexibility of creating advanced hyperlinks across these document formats and viewers that cannot be realised with existing linking solutions or link models of existing document formats. A user study further investigates the user experience when creating and navigating cross-document hyperlinks.

Previous research in Human-Computer Interaction and Personal Information Management has revealed certain user behaviour in associating information across physical and digital documents. Nevertheless , there is a lack of empirical studies on user needs and behaviour when defining these associations. In this paper, we address this lack of empirical studies and provide insights into strategies that users apply when associating information across physical and digital documents. In addition, our study reveals the limitations of current practices and we suggest improvements for associating information across documents. Last but not least, we identify a set of design implications for the development of future cross-document linking solutions.

However, most existing document linking approaches show some shortcomings in terms of the offered link granularity and cannot easily be extended to support new document formats. More recently, we see new document formats such as the Office Open XML (OOXML) standard which facilitate the linking to parts of certain document formats. We present a dynamically extensible open cross-document link service enabling the linking and integration of arbitrary documents and multimedia content. In our link browser, emerging document formats are supported via visual plug-ins or by integrating third-party applications via gateways. The presented concepts and architecture for dynamic extensibility improve the document life cycle in so-called cross-media information spaces and enable future-proof cross-document linking.

Nevertheless, most existing document formats only support links to web resources but not to parts of third-party documents. An open cross-document link service should address the multitude of existing document formats and be extensible to support emerging document formats and models. We present an architecture and prototype of an open cross-document link service and browser that is based on the RSL hypermedia metamodel. A main contribution is the specification and development of a visual plug-in solution that enables the integration of new document formats without requiring changes to the cross-document browser's main user interface component. The presented visual plug-in mechanism makes use of the Open Service Gateway initiative (OSGi) specification for modularisation and plug-in extensibility and has been validated by developing data as well as visual plug-ins for a number of existing document formats.
