  Scientific research is highly structured and some of that structure is
reflected in research reports. Traditional scientific research reports are
yielding to interactive documents which expose their internal structure and are
richly linked to other materials. In these changes, there are opportunities to
take advantage of the structure in scientific research reports which previously
have not been systematically captured. Thus, we explore ways of capturing more
of the structure of research in reports about the research and we use that
structure to support the development of a new generation of document browsers
which include novel interaction widgets. We apply the browsers incorporating
the conceptual modeling framework to full-text research reports from the Public
Library of Science (PLoS). In addition, we describe the application of
model-oriented constructs to facilitating highly interlinked digital libraries.
