TL;DR: The versatility of the HAM can be illustrated by showing how Guide buttons, intermedia webs, and NoteCard FileBoxes can be implemented using its storage model.
Abstract: The HAM is a transaction-based server for a hyper text storage system. The server is designed to handle multiple users in a networked environment. The storage system consists of a collection of contexts, nodes, links, and attributes that make up a hypertext graph. The versatility of the HAM can be illustrated by showing how Guide buttons, intermedia webs, and NoteCard FileBoxes can be implemented using its storage model.

TL;DR: The Dexter hypertext reference model as mentioned in this paper is an attempt to capture, both formally and informally, the important abstractions found in a wide range of existing and future hypertext systems, providing a principled basis for comparing systems as well as for developing interchange and interoperability standards.
Abstract: This paper presents the Dexter hypertext reference model. The Dexter model is an attempt to capture, both formally and informally, the important abstractions found in a wide range of existing and future hypertext systems. The goal of the model is to provide a principled basis for comparing systems as well as for developing interchange and interoperability standards. The model is divided into three layers. The storage layer describes the network of nodes and links that is the essence of hypertext. The runtime layer describes mechanisms supporting the user’s interaction with the hypertext. The within-component layer covers the content and structures within hypertext nodes. The focus of the model is on the storage layer as well as on the mechanisms of anchoring and presentation specification that form the interfaces between the storage layer and the within-component and runtime layers, respectively. The model is formalized in the specification language Z, a specification language based on set theory. The paper briefly discusses the issues involved in comparing the characteristics of existing systems against the model.

TL;DR: A hand conversion to HTML of the original MacWord (or Word for Mac?) document written in March 1989 and later redistributed unchanged apart from the date added in May 1990 is provided.
Abstract: https://www.w3.org/History/1989/proposal.html 1/15 A hand conversion to HTML of the original MacWord (or Word for Mac?) document written in March 1989 and later redistributed unchanged apart from the date added in May 1990. Provided for historical interest only. The diagrams are a bit dotty, but available in versioins linked below. The text has not been changed, even to correct errors such as misnumbered figures or unfinished references.

TL;DR: In this article, a set of hypermedia linking services enable client applications to incorporate hypermedia capabilities in an open system architecture, and the users are provided with a consistent hypermedia interface completely managed by the hypermedia services and not by the client application itself.
Abstract: A set of hypermedia linking services enable client applications to incorporate hypermedia capabilities in an open system architecture. The users are provided with a consistent hypermedia interface completely managed by the hypermedia services and not by the client application itself. The graphical user interface includes methods for menu handling, dialog box presentation and pointing device message handling, e.g., mouse message handling. Normal hypermedia activities such as object management, object creation, object deletion and object modification is provided. In addition, an open system searching mechanism is provided to satisfy broad non-context requests for information by the user without sacrificing the advantages of an open hypermedia environment.

TL;DR: A formal definition of the Trellis model of hypertext is presented and an authoring and browsing prototype called αTrellis that is based on the model is described, which is a generalization of existing directed graph-based forms ofhypertext.
Abstract: We present a formal definition of the Trellis model of hypertext and describe an authoring and browsing prototype called aTrellis that is based on the model. The Trellis model not only represents the relationships that tie individual pieces of information together into a document (i.e., the adjacencies), but specifies the browsing semantics to be associated with the hypertext as well (i.e., the manner in which the information is to be visited and presented). The model is based on Petri nets, and is a generalization of existing directed graph-based forms of hypertext. The Petri net basis permits more powerful specification of what is to be displayed when a hypertext is browsed and permits application of previously developed Petri net analysis techniques to verify properties of the hypertext. A number of useful hypertext constructs, easily described in the Trellis model, are presented. These include the synchronization of simultaneous traversals of separate paths through a hypertext, the incorporation of access controls into a hypertext (i.e., specifying nodes that can be proven to be accessible only to certain classes of browsers), and construction of multiple specialized (tailored) versions from a single hypertext.

TL;DR: This book describes and evaluates a range of webicators for aspects of societal or scholarly impact, discusses the theory and practice of using and evaluating web indicators for research assessment and outlines practical strategies for obtaining many web indicators.
Abstract: In recent years there has been an increasing demand for research evaluation within universities and other research-based organisations. In parallel, there has been an increasing recognition that traditional citation-based indicators are not able to reflect the societal impacts of research and are slow to appear. This has led to the creation of new indicators for different types of research impact as well as timelier indicators, mainly derived from the Web. These indicators have been called altmetrics, webometrics or just web metrics. This book describes and evaluates a range of web indicators for aspects of societal or scholarly impact, discusses the theory and practice of using and evaluating web indicators for research assessment and outlines practical strategies for obtaining many web indicators. In addition to describing impact indicators for traditional scholarly outputs, such as journal articles and monographs, it also covers indicators for videos, datasets, software and other non-standard scholarly outputs. The book describes strategies to analyse web indicators for individual publications as well as to compare the impacts of groups of publications. The practical part of the book includes descriptions of how to use the free software Webometric Analyst to gather and analyse web data. This book is written for information science undergraduate and Master’s students that are learning about alternative indicators or scientometrics as well as Ph.D. students and other researchers and practitioners using indicators to help assess research impact or to study scholarly communication.
