OSGeo Members and Geowankers,


Has anyone done any work/research on the typical lifecycle of geospatial
datasets? I was working on my Metadata chapter for the Free GIS Book
this morning and I found myself trying to explain how metadata is
related to this life cycle. (The basic idea of this section in the
chapter is that metadata should be updated at each point in the life
cycle.)That's when I realized I needed a better idea of what this life
cycle is. 


Here is what I've come up with:


Geospatial data is created.

Geospatial data is cataloged.

Geospatial data is maintained.

Geospatial data is consumed.

Geospatial data is archived or "decommissioned".


I know this isn't as simple as I would like it to be. For example, data
could be consumed before it is maintained or cataloged. Maybe what I
need is something like a loop instead of a timeline, or even a flow
chart of some type.


At any rate, if there has been any work on understanding the typical
life cycle of a geospatial data set I'd like to read it. Or if you have
personal thoughts on how it can be represented please share them.
