Hi,
This isn't strictly a libxml issue but hopefully it's of interest.
For Guppi, I want the user to be able to load and save several kinds of
thing - data sets (basically lists of numbers), plots (colors and sizes
and so on of the plot), and the entire session (where the windows are,
which datasets and plots are loaded).
So to avoid lots of copies of data, I would like to be able to save
"pointers" to other files. These pointers could represent a URL, or
perhaps even a persistent Bonobo object such as Gnumeric. The important
thing is the ability to add new kinds of pointer.
Then people can do things like "publish" a data set on the web, perhaps
one which changes daily, and distribute a plot file which displays the
data set in a certain way. More commonly, you would just have a single
data set file on a local disk and several plots referring to it.
I'm wondering if there's a standards-based way to do this, or if I should
just make up my own little tag. In particular I've been looking at the
XLink spec: http://www.w3.org/TR/WD-xlink
Is that perhaps appropriate or is it intended more for interactive
browsing applications?
Any nice suggestions?
Thanks,
Havoc
