[uf-discuss] Implementation Idea for "prev" and "next"

[Lorenzo De Tomasi]

My past thoughts about this subject (always updated at
http://isotype.wordpress.com/2006/09/20/document-navigation-module/ )
are the following.
I hope they can be interesting for you.
 Thank you.

Document navigation module  			 				

Every resource (a book, an e-book, a web site, but also a movie, a
music etc.) can be divided in sections.

Sections can be:
autonomous,
sequential (monodimensional),
linked, connected with relationships (bidimensional or multidimensional)
…

A subsection is a section contained in a section. A subsection can
contain another (sub)section, so there are sections of different
levels (first, second etc.)
 I think it's fundamental to distinguish to different types of content
organization and, consequently, fruition: lineartypical of traditional
books like romances, essays etc. The fruition is sequential,
traditionally organized in sections like chapters, paragraphs and
single lines.hypertextualnon linear, multidimensional with a net
structure typical of traditional books like dictionaries,
encyclopedias etc. This typology has increased its potential with the
development of information and communication technologies, the web in
particular.

In an hypertextual resource we can always suggest a preferred linear
path, that explores sequentially the whole content.
Linear content indexRefers to a section providing an index for a
collection of sections.startRefers to the first section in a
collection of sections. This link type tells search engines which
section is considered by the author to be the starting point of the
collection.nextRefers to the next section in a linear sequence of
sections. User agents may choose to pre-load the "next" section, to
reduce the perceived load time.prevRefers to the previous document in
an ordered series of documents. Some user agents also support the
synonym "Previous".
Hypertextual content navigationThis is the navigation bar on a web
document. This is typically a list of links to other pages on the site
or other areas of the same document.searchThis is the search section
of a web document. This is typically a form used to submit search
requests about the site or a more general Internet wide search
service.bookmarkRefers to a bookmark. A bookmark is a link to a key
entry point within an extended document. The title attribute may be
used, for example, to label the bookmark. Note that several bookmarks
may be defined in each document.
