archive-navigation
time, date, navigation
Description
archive navigation is a timeline tool somewhere near alpha state.
and datasources are crawled to build a nested navigation poiting to $root/archive/$year/$month/$day
exslt (which seem to be part of libxslt) is needed because of exessive use of exslt:node-set().
- page specific timelines
- timeline offsets
- time points like first day/second day
- precission up to minutes
- dynamic link targets like $root/festival/first-day/2pm
- time spans
will be done in the future.
