Hi.
I would like to have a component that is able to create arbitrary
hypertext, and I'm not sure, if there's a better way to do that than I
have in mind currently.
My database contains spatial geo data from the OpenStreetMap project,
and I would like to generate texts as they probably could be part of an
old styled text adventure or something like that.
Let's do an example:
[snip]
The page /explore/way/12423 refers to one object of the database, a
geographic linestring, e.g. a street.
From the database I get more information about the way and would like
to assemble these into a text like the following:
You are at the [Abbey Road] between [Marcus Square] and [Church Alley].
The [Westminster Abbey] is on your left.
From here you can cross the [Marcus Square] to straight ahead follow
the [Abbey road towards the River way], or you can...
[snap]
I think, it's enough as an example.
The parts in brackets should be page links or action links, leading e.g.
to the /explore/way/2413 (and other ids) for other streets or
/details/3432 for details about the abbey or other points of interests -
imagine opening hours of a bar, service times for a church or a website
link.
Currently I know two variants how to achieve that:
1) Use a template that models all possibilities on how to assemble that
kind of text, e.g. as a big loop with many ifs assembling atomic parts
(like links, static texts and so on) together, and create a
corresponding object collection in java.
2) Create a component without template and render directly - with the
big drawback that I have not yet any idea how to inject tapestry
components like ActionLink or PageLink to that.
Any hints or example pages are welcome.
regards
Peter
