A State of Art Survey on zz-structures

Dattolo A., Luccio F.

Abstract: ZigZag-structures are particular data structures capable of representing both hypertextual information and contextual interconnections among different information. The focus of this paper is to stimulate new research on this topic, by providing, in a state of the art survey, a short description and comparison of all the material that, to the best of our knowledge, is related to zz-structures: informal and formal descriptions, implementations, languages, demonstrations, projects and applitudes of zz-structures; in fact, despite their large use in different fields, the literature lacks of an exhaustive and up-to-date description of them.

A formal description of zz-structures

Dattolo A., Luccio F.

Abstract: The focus of this paper is on particular and innovative structures for storing, linking and manipulating information: the ZigZag-structures. In the last years, we worked at the formalization of these structures, retaining that the description of the formal aspects can provide a better understanding of them, and can also stimulate new ideas, projects and research. This work presents our contribution for a deeper discussion on ZigZag-structures.

From ZigZag™ to BigBag: Seeing the wood and the trees in online archive finding aids

Anderson I.

Abstract: This paper reports on a one year speculative research project that sought to test the technical feasibility, practical implications and usability of transforming an XML Encoded Archival Description (EAD) finding aid into an XML ZigZag™ structure and applying a relational browser interface.

Creating Dynamic Wiki Pages with Section-Tagging

Helic D., Saeed A.U., Trattner C.

Abstract: Authoring and editing processes in wiki systems are often tedious. Sheer amount of information makes it difficult for authors to organize the related information in a way that is easily accessible and retrievable for future reference. Social bookmarking systems provide possibilities to tag and organize related resources that can be later retrieved by navigating in so-called tag clouds. Usually, tagging systems do not offer a possibility to tag sections of resources but only a resource as a whole. However, authors of new wiki pages are typically interested only in certain parts of other wiki pages that are related to their current editing process.

This paper describes a new approach applied in a wiki-based online encyclopedia that allows authors to tag interesting wiki pages sections. The tags are then used to dynamically create new wiki pages out of tagged sections for further editing.

Towards XML Transclusions

Di Iorio A., Peroni S., Vitali F., Lumley J., Wiley A.

Abstract: The idea of transclusion has been at the same time the strength and weakness of Xanadu: some people considered it as an extremely powerful mechanism to get any version of any fragment of any document in a global shared document space, others as a very complex solution too difficult to be actually implemented and delivered. We believe transclusions are still worth implementing and would allow designers to build very sophisticated hypermedia applications. On the other hand, we are aware that the original design of Xanadu cannot be implemented uprooting the current systems, protocols and technologies - in primis the World Wide Web and XML. In fact, there is a great distance between the original data model of transclusions - strongly based on external referencing mechanisms - and the XML data model - strongly based on hierarchical structures and embedded markup.

This paper investigates to what extent the concept of transclusion can be shaped for the world of XML, and studies simplified models for building functionalities inspired to Xanadu. Particular attention is given to the support for tracing fragments provenance in multi-source documents and for synchronizing distributed content through transclusions.

The paper also traces a roadmap to actually implement transclusions for XML - identifying three incremental steps - and briefly describes some experimental prototypes.
