CMIFed : a presentation environment for portable hypermedia documents by Guido Van Rossum ( Book )
3 editions published in 1993 in English and held by 10 WorldCat member libraries worldwide
Abstract: "This paper discusses the architecture and implementation of CMIFed, an editing and presentation environment for hypermedia documents. Typically such documents contain a mixture of text, images, audio, and video (and possibly other media), augmented with user interaction. CMIFed allows the author flexibility in specifying what is presented when, using multiple simultaneous output channels. Unlike systems that use a timeline or scripting metaphor to control the presentation, in CMIFed the user manipulates a collection of events and timing constraints among those events. Common timing requirements can be specified by grouping events together in a tree whose nodes indicate sequential and parallel composition. More general timing constraints between events can be added in the form of synchronization arcs. User interaction is supported in the form of hyperlinks. We place CMIFed in the context of the CMIF model for hypermedia documents, which formalizes the properties of hypermedia presentations in a platform-independent manner."
Structured multimedia authoring by Lynda Hardman ( Book )
3 editions published in 1993 in English and held by 10 WorldCat member libraries worldwide
Abstract: "We present the user interface to the CMIF authoring environment for constructing and playing multimedia presentations. The CMIF authoring environment supports a rich hypermedia document model allowing structure-based composition of multimedia presentations and the specification of synchronization constraints between constituent media items. An author constructs a multimedia presentation in terms of its structure and additional synchronization constraints, from which the CMIF player derives the precise timing information for the presentation. We discuss the advantages of a structured approach to authoring multimedia, and describe the facilities in the CMIF authoring environment for supporting this approach. The authoring environment presents three main views of a multimedia presentation: the hierarchy view is used for manipulating and viewing a presentation's hierarchical structure; the channel view is used for managing logical resources and specifying and viewing precise timing constraints; and the player for playing the presentation. We present the authoring environment in terms of a short example: constructing a walking tour of Amsterdam."
The Amsterdam hypermedia model : extending hypertext to support real multimedia by Lynda Hardman ( Book )
3 editions published in 1993 in English and held by 10 WorldCat member libraries worldwide
Abstract: "A model of hypermedia is presented that allows the combination of 'hyper-structured' information with dynamic multimedia information. The model is derived by extending the Dexter hypertext reference model and the CMIF multimedia model. The Amsterdam hypermedia model allows the following, in addition to the model provided by Dexter: the composition of multiple dynamic media, in order to specify a collection of time-based media making up a complete multimedia presentation; the definition of 'channels' for specifying default presentation information, allowing the specification of the presentation characteristics of nodes at a more general level than that for an individual node; the composition of existing presentations into larger presentations, taking into account possible clashes of resource usage; the inclusion of temporal relations while maintaining the separation of structure and presentation information, where time-based relationships are treated as presentation information; the specification of 'context' for anchors, in order to determine whether on following a link a part, or the whole, of the presentation is replaced by the information at the destination of the link. The Amsterdam hypermedia model enables the description of structured multimedia documents, incorporating time at a fundamental level, and extending the hypertext notion of links to time-based media and compositions of different media. The paper is organised as follows. The Dexter hypertext model and the CMIF multimedia model are summarised, and their limitations for use as a more general hypermedia model are discussed. The extensions included in the Amsterdam hypermedia model are described and a summary of the resulting model is given."

The ABC structure editor : structure-based editing for the ABC programming environment by Lambert Meertens ( Book )
2 editions published in 1992 in English and held by 6 WorldCat member libraries worldwide
Abstract: "ABC is an interactive programming language where both ease of learning and ease of use stood high amongst its principle design aims. The language is embedded in a dedicated environment that includes a structure-based editor. To fit in with the design aims, the editor had to be easy to learn, demanding a small command set, and easy to use, demanding a powerful command set and strong support for the user in composing programs, without enforcing a computer-science understanding of issues of syntax and the like. Some novel design rules have led to an interesting editor, where the user may enter and edit text either structurally or non- structurally, without having to use different 'modes'."
