Set up effective cross-document navigation
With PDFs to be used online, it is generally
recommended to construct a publication as a set of multiple chapters
(inter-linked PDFs), each with its own unique Title, Subject
and Keywords fields, instead of a single-file PDF.
Benefits of multiple chapters include:
- The Search Results window displays the
titles of matching documents, with their relevancy ranking; keywords
can be assigned to individual chapters, rather than to the entire
book. This is much more effective than searching a single PDF.
- The title bar reflects the chapter title,
assisting orientation as to the current location.
- Multiple chapters can be opened simultaneously,
each in a separate window.
- Faster access when used on the web.
Often, PDF producers resort to the single
PDF approach due to the extra work related to interactive features
involved with multiple PDFs. SP Navigation Assistant was created
to minimize this extra work, enabling you to include the navigation
features once in your FrameMaker files so that they are automatically
present in the resulting PDFs.
With TimeSavers + Navigation Assistant,
you can define smart cross-file features which "know"
what are the next and previous file in your project, what files
are first and last:
- Next/previous file buttons
- Next/previous page buttons that take
the reader across files when at the last/first page in a file
- Bookmarks to all other PDFs participating
in your project
Cross-file tabs can be used to provide
quick-access to key PDFs included in your document collection.
You can also create dynamic document maps, showing all PDFs included
in a PDF collection as boxes, with additional relationship and
grouping information. The currently-viewed PDF is highlighted,
providing a "You are here" indication; all other boxes
are linked to the corresponding PDFs. The box structure can also
be placed directly on a body page. Alternatively, to facilitate
automatic updates from a single definition, the box structure
can be defined in a named referenced frame on a reference page,
and then included on a body page using a paragraph with a Frame
Above or Frame Below setting.
