Journal publishing with Acrobat: the CAJUN project
The publication of material in electronic form should ideally preserve, in a unified document representation, all of the richness of the printed document while maintaining enough of its underlying structure to enable searching and other forms of semantic processing. Until recently it has been hard to find a document representation which combined these attributes and which also stood some chance of becoming a de facto multi-platform standard.
This paper sets out experience gained within the Electronic Publishing Research Group at the University of Nottingham in using Adobe Acrobat software and its underlying PDF (Portable Document Format) notation. The CAJUN project1 (CD-ROM Acrobat Journals Using Networks) began in 1993 and has used Acrobat software to produce electronic versions of journal papers for network and CD-ROM dissemination. The paper describes the project's progress so far and also gives a brief assessment of PDF's suitability as a universal document interchange standard
Incorporating interactive 3-dimensional graphics in astronomy research papers
Most research data collections created or used by astronomers are
intrinsically multi-dimensional. In contrast, all visual representations of
data presented within research papers are exclusively 2-dimensional. We present
a resolution of this dichotomy that uses a novel technique for embedding
3-dimensional (3-d) visualisations of astronomy data sets in electronic-format
research papers. Our technique uses the latest Adobe Portable Document Format
extensions together with a new version of the S2PLOT programming library. The
3-d models can be easily rotated and explored by the reader and, in some cases,
modified. We demonstrate example applications of this technique including: 3-d
figures exhibiting subtle structure in redshift catalogues, colour-magnitude
diagrams and halo merger trees; 3-d isosurface and volume renderings of
cosmological simulations; and 3-d models of instructional diagrams and
instrument designs.Comment: 18 pages, 7 figures, submitted to New Astronomy. For paper with

Creating Structured PDF Files Using XML Templates
This paper describes a tool for recombining the logical structure from an XML document with the typeset appearance of the corresponding PDF document. The tool uses the XML representation as a template for the insertion of the logical structure into the existing PDF document, thereby creating a Structured/Tagged PDF. The addition of logical structure adds value to the PDF in three ways: the accessibility is improved (PDF screen readers for visually impaired users perform better), media options are enhanced (the ability to reflow PDF documents, using structure as a guide, makes PDF viable for use on hand-held devices) and the re-usability of the PDF documents benefits greatly from the presence of an XML-like structure tree to guide the process of text retrieval in reading order (e.g. when interfacing to XML applications and databases)
CD-ROM Acrobat Journals Using Networks
The available technologies for publishing journals electronically are surveyed. They range from abstract representations, such as SGML, concerned largely with the structure of the document, to formats such as PostScript which faithfully model the layout and the appearance. The issues are discussed in the context of choosing a format for electronically publishing the journal: Electronic Publishing -- Origination, Dissemination and Design. PostScript is neither widely enough available nor standardised enough to be suitable; a bitmapped pages approach suffers from being resolution-dependent in terms of the visual quality achievable. Reasons are put forward for the final choice of Adobe s new PDF document standard for creating electronic versions of the journal
PDF/A-3u as an archival format for Accessible mathematics
Including LaTeX source of mathematical expressions, within the PDF document
of a text-book or research paper, has definite benefits regarding
`Accessibility' considerations. Here we describe three ways in which this can
be done, fully compatibly with international standards ISO 32000, ISO 19005-3,
and the forthcoming ISO 32000-2 (PDF 2.0). Two methods use embedded files, also
known as `attachments', holding information in either LaTeX or MathML formats,
but use different PDF structures to relate these attachments to regions of the
document window. One uses structure, so is applicable to a fully `Tagged PDF'
context, while the other uses /AF tagging of the relevant content. The third
method requires no tagging at all, instead including the source coding as the
/ActualText replacement of a so-called `fake space'. Information provided this
way is extracted via simple Select/Copy/Paste actions, and is available to
existing screen-reading software and assistive technologies.Comment: This is a post-print version of original in volume: S.M. Watt et al.
