Multi-Head Multi-Tail Mosaic

Brian C. Ladd Michael Capps P. David Stotts Rick Furuta

The explosive growth of the World Wide Web is attributable, in large part, to the simplicity of the distributed graph model it uses for information storage and retrieval. The model is simple, general, and ubiquitous; the reader may choose almost any browsing path. Information providers, though, then use every trick at their disposal in an attempt to increase their power over how readers browse their pages. Two major shortcomings of current Web protocols are lack of support for concurrent browsing and synchronization of multiple browsing paths. This paper presents a computer-aided instruction scenario where the author (instructor) must overcome these weaknesses. In traditional hypermedia systems, a link relates a single source node to a single destination node. Projects such as Xanadu [3] and Trellis [6] previously generalized links to allow connection of multiple source nodes to multiple destination nodes. This generalization, which we term a Multi-Head/Multi-Tail (MHMT) link, allows an author to create concurrent browsing paths in a document, and to synchronize those concurrent paths if desired. This has applications to groupware as well as to documents browsed by single users. We describe our solution embodied in MHTML as a straightforward extension to HTML for defining multi-head/multi-tail links and an experimental browser called MMM that implements the extensions.

Early Prototypes of the Repository for Patterned Injury Data

Prasun Dewan Kevin Jeffay John B. Smith P. David Stotts William R. Oliver

ABSTRACT We have constructed a proof-of-principle system for support-ing collaborative forensic medicine. The early prototype isbuilt on ABC/DGS, a graph-server and collaborative hyper-media system built in the UNC Collaboratory. A secondprototype is underway that has more flexible control ofmulti-person creation of, and access to, the shared patientdata and pathology artifacts. Created with Dewan’s Suite,this version maintains consistent yet different independentviews of the underlying data, and moderates access throughthese views. We conclude by describing a planned third pro-totype, to be built not on ABC, but on a modification of theWWW httpd distributed data server. KEYWORDS: forensic pathology, ABC, DGS, Suite, viewcoupling, access control, group access, World Wide Web,httpd, distributed data server OVERVIEW Forensic specialists have long understood the importance oftoolmarks and trace evidence in the investigation of violentcrimes and in successfully prosecuting those who committhese acts. However, except in specific areas such as foren-sic odontology and tire and shoeprint impression analysis,there is little formal work in the area of patterned injuryanalysis as a problem in forensic pathology. A better abilityto use patterned injuries to determine what object or objectswere used to commit violence, matching a possible weaponor object to a wound with some degree of certainty, or ofmatching a mark on a body with an object at a scene wouldbe a tremendous boon.We believe there are three primary reasons why large-scaleformal work has not been done. The first is that developingexpertise in the area is profoundly experiential. The universeof possible objects and the variety of wounds that any par-ticular object can cause is large, and experience is gainedslowly. Second, there is no central collection of patternedinjuries. A centralized collection of solved cases provides auniform teaching base, a standard by which other cases andother approaches to cases can be evaluated, and a resource forapproaching unsolved cases. Finally, it is difficult forpathologists to consult on a large-scale basis about patternedinjuries. The usefulness of multi-person interactive consul-tation about images has been demonstrated in radiology andother medical disciplines, and is a driving force behind theimaging workstation systems being implemented by theFBI.The Repository for Patterned Injury Data (RPID) project isaddressing each of these problems. First, we are building adigital library for forensic medicine, an electronic informa-tion repository to support collaboration on medical cases in-volving patterned injuries. The library is to contain tradi-tional data forms (text, images) as well as newer multi-mediadata forms (audio, video, handwriting). Second, we are as-sembling a computer and communications infrastructure toprovide access to the library for real-time interactive consul-tation and database exploration. Third, we will carry out acontinuous series of evaluative and experimental studies tovalidate the designs and guide further system development.The design of the RPID was reported in the first DigitalLibraries conference [SSDJ94]. For clarity here, we brieflysummarize the structure and goals of the project. Followingthis recap, we illustrate the current prototypes and discussthe interactions we have established for consulting patholo-gists. We conclude with our plans for subsequent versionsof the RPID.

Dynamic characteristics of hypertext

Richard Furuta P. David Stotts

We consider a dynamic hypertext as one that changes even in the absence of user activity.Hypertexts are comprised of structure, content, and context, and dynamic operations may affect any of them.Dynamic operations are synchronous (related to the hypertext's description) or asynchronous.We call the former timers and sensors.In this paper we argue that such dynamic characteristics are an impoitant component of many hypertext systems, surveying existing implementations to examine the different realizations of dynamic operations, and that dynamic plications are also of importance within the hypertext domain.
