Landon, Sure thing. We just implemented it in geotools. Its a good feature model... but the more i think about it the more i feel that keeping data format access independent of the feature model is a crucial design decision. Also note that the geoapi feature model adds a significant amount of comp

Justin, Let me investigate the feature model maintained by GeoAPI. I remember looking at it when this issue came up before, but I can't remember why we decided not to use it. I should have good reasons for suggesting something new, as Rob stated. I'll poke around on the GeoAPI list. I may respond

Hi Landon, Glad my ideas are not too crazy :). And you raise a good point with the manpower thing. And indeed many of the geotools developers will be core implementors in this library as well. And hopefully the udig developers, jump developers, etc... The reason I don't want it part of geotools i

This gets to an issue thats been bothering me for some time - the separation of concerns with geotools. Generally speaking, there are some operations that require a trivial view of business data, such as rendering to a map, and others that require manipulation of the data, and others that require h

Justin, It sounds like you and I think alike. I believe that all of your ideas have merit. I wonder though, if the library could still be "maintained" and hosted by GeoTools. I realize the man power for this might not be available, but I would be willing to give some time to this effort if GeoTool

Hi Landon, I never jumped into this thread last time it came around but it is something i am very interested in. As of late I have become quite frustrated with geotools data access support. And compared to other projects like ogr the number of formats we actually do support is laughable. When jod

2007-11-13 Thread Sunburned Surveyor
A while back I worked with another OpenJUMP Developer and a couple of guys from GeoTools on a framework for what we called DataObjects. A DataObject class could represent simple spatial features or non-spatial features at a very low or abstract level. The goal was to eventually create a DataSource
