This paper presents an approach for providing hypertext services in this heterogeneous setting. Central notions of the approach include the following. Anchors are established with respect to interactive views of objects, rather than the objects themselves. Composable, n-ary links can be established between anchors on different views of objects stored in distinct object bases. Viewers (and objects) may be implemented in different programming languages afforded by a client-server architecture. Multiple, concurrently active viewers enable multimedia hypertext services. The paper describes the approach and presents an architecture which supports it. Experience with the Chimera prototype and its relationship to other systems is described.","PeriodicalId":112968,"journal":{"name":"European Conference on Hypertext","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116267885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DHM development framework is based on the Dexter Hypertext Reference Model, which introduces a notion of composite to model editors with complex or multiple types of contents. The original Dexter notion of composites is, however, insufficient to cover structural composites including or referencing other components. Thus the DHM framework has been extended with generic composite classes suited to support structures within the hypermedia network itself. The paper presents and discusses the design of the generic composite classes belonging to the STORAGE and RUNTIME layers of the framework. A central aspect of the design is that the structuring mechanism is a true composite with a collection of components as its contents rather than an atomic component with links to other components as in the classical systems such as NoteCards, Intermedia, and KMS. It is also shown how the powerful generic classes can be used to implement a variety of useful hypermedia concepts such as: hierarchy by inclusion, hierarchy by reference, virtual and computed browsers, TableTops and GuidedTours.","PeriodicalId":112968,"journal":{"name":"European Conference on Hypertext","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125752191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collections can contain other collections (nested collections). Collections can be regarded as sets, but they can also have an inner structure. Collections can be created in several ways: manually, through queries, by operations on other collections, by exploiting links, etc.\u0000Collections introduce a navigational pattern, based on their structure, that is different from the standard node&link navigation.\u0000If active media are considered, collections allow the design and implementation of complex synchronisation strategies, difficult to obtain otherwise.\u0000The paper describes the motivations for using collections, their structure, their navigational capabilities and a number of possible authoring mechanisms. It also examines the interplay between standard navigation and collection navigation, possible synchronization strategies for collections, as well as the requirements for the definition of a runtime support (which could be used to extend the runtime layer of the Dexter Model).","PeriodicalId":112968,"journal":{"name":"European Conference on Hypertext","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122078435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Hypermedia Authoring Research Toolkit (HART) was developed to support the human editor during this media-to-hypermedia conversion process. The tool's goal is to help improve the correctness and completeness of the hypermedia database, as well as reduce the media-to-hypermedia conversion cost.\u0000We believe it is not possible to properly convert media to hypermedia without the participation of a human editor during the transformation. It is therefore necessary to develop tools to assist the human during this process.

Combining all traversals in a single chronological history log would violate the user's mental model and cause disorientation. In this paper we introduce task-based backtracking, a technique for backtracking within the various logical tasks a user may be working on at any given time. We present a preliminary algorithm for its implementation. We also discuss several ramifications of multi-window backtracking including the types of events history logs must record, deleting nodes from history logs that appear in multiple logical tasks, and in general the choices hypermedia designers face in multi-window environments.","PeriodicalId":112968,"journal":{"name":"European Conference on Hypertext","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115069266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
