To the developers of Semantic Timelines, part of Semantic Result Formats:
Well, I've switched my timestamp properties to the standard Date
datatype (after my long and intense project to enhance it to satisfy my
requirements), and upgraded SMW to version 1.4.3 and SRF to version 1.4.5.
Now I'm experimenting with timelines.
And I've found out some very interesting things--or rather, I have some
Why can't I build a timeline using events that took place before the
birth of Christ, or the "common era," if you prefer that notation? Does
Timeline have an "oldest allowable year"? My guess is the year 1000
AD/CE in the proleptic Gregorian calendar. All I know is this: when I
asked for a timeline of the Hebrew Kings of Judah, I got a notice: "Use
soap. But when I simply queried "[[Born > 1 January 1000]]" and set
timelineposition = middle, I got a point at the birth of James Ussher,
during the lifetimes of Johannes Kepler and Galileo Galilei. However,
even that display had a problem:
Why is it, that when I ask for a timeline or an eventline that creates
bands between two dates for one article (typically, Born-Died, or
Began-Ended), the timeline markers are hard-limited to YEAR and MONTH? I
tried to change them to DECADE and CENTURY (these were biographical
articles), and no soap. However, single-event timelines (like querying
celestial bodies having a common primary and sorting by Date of
Discovery) do allow DECADE and CENTURY as timeline markers.)
Don't get me wrong; timelines are now very useful to me. I rather
enjoyed the feature that allows me to display non-date properties in a
dialog balloon with any given event. For example, I can query the
planets that were not known to the ancients, plot them on a timeline by
date of discovery, and for each planet I can have the astronomer's name
and any other properties I want, show up when I click on the dot that
represents that planet.
But I'd still like to know what the limitations of Timeline are, so that
I can advise my editors on how and when to use them.
For that matter: I have the PDF user's manual for SMW. Now does someone
have a user's manual for SRF? Specifically, how can I use Calendar? What
does Exhibit do? What is the difference between Timeline and Eventline?
