       PDFs and data impoverishment

Henry Rzepa: Publishers are likely to love interactive PDF, since it is
easy to archive. However ... such objects are data impoverished.
Whereas with Jmol, one is obliged to provide semantically accurate
data (e.g. CML or equivalent), the PDF object is simply a (pre)rendering
of that data. Thus reconstituting a useful molecule from Jmol is trivial
(and that reconstitution can then be used for many other purposes),
reconstituting a molecule from a 3D PDF is likely to be non trivial, and
will almost certainly suffer information loss compared to the original
data. By all means, provide both, but I strongly urge that a 3D PDF
should not be the only object provided.

Interactive authorship: publBio

             • Start with the data (PDB)
                 example 3jw1

             • Add structured text
             • Online look-up:
                 • authors
                 • references
                 • crystallization solution components
             • Validation
                 • references
             • Visualisation (Jmol)
             • Update data file as submission
Uniform (compatible) markup systems
              • Crystallographic Information
                Framework (CIF)
                 • Treat data/metadata,
                 text/numerical data as peers
                 • Domain-specific extensions
                 (dictionaries = ontologies)
                 • Image format
              • Some data fields may need
                to contain richer content
                 • Text markup
                 • Mathematical equations
                 • Interactive figure scripts
              • Machine validation of
                dictionary attributes
              • Methods
•   The working scientist really wants to interact with the data
•   What interactive PDF offers is currently limited
•   Publishers should develop compatible architectures
•   Need domain-specific implementations (learned societies)
•   Investment in new applications; integration with workflow
•   Education for a new paradigm
•   Archiving
     •   requires more standardisation
     •   proper compound document model
     •   concentrate on data (or semantic content), not the implementation
     •   ‘record not what it looks like, but what you are looking at’
• Distributed content sources
     • data not necessarily integral part of document
     • retrieval of non-discrete data sets
