Re: [JPP-Devel] Adding attributes and attribute values
as far as i remember it is not possible to simply extend the
FeatureSchema of a FeatureDataSet and the set the attribute.
You need to "copy/transform" every Feature towards the new Schema and
create a new Feature and a new Feature Collection.
see for instance:
org.openjump.core.spatialAttributeOps.copyFeature(Feature feature,
FeatureSchema newSchema)
i think in the pirol package are also similar functions:
de.fho.jump.pirol.apiTools.FeatureCollectionTools

[JPP-Devel] OpenJUMP 1.2 Beta vs Openjump Nightly Build
Hi all, I saw that OpenJUMP 1.2 Beta is still available on Sourge forge. Nevertheless OJ nightly build walked more further. Many important bugs were solved (see snap options)and there are also some small but significant modifications (see the desapeared "Open or Save datastore as file.." function from "file" menu). Many new user would be confused and download the buggy OJ Beta instaead of new nightly build ones which seem to work better. Questions/proposals: 1) is it time to upgrade OJ BETA on Sourgeforce to one of the latest nightly build? 2) would we call it OpenJUMP 1.2 (no beta). Nightly Builds solve bugs but they are on the road to something different (OJ 1.3?) because of the small modification and other up-to-come projects (ex. see Paul Austins' Open (File) Plugin project) 3) What about to plan a sort of road map for the future (OJ 1.3 and maybe OJ 1.4)?

Re: [JPP-Devel] GeoJP2
This is interesting. It sounds like the JPEG 2000 committee didn't know if there were submarine patents, and I wonder if this was stated by the committee as a way to deflect liability. Is there any opinion on whether there is a danger of the JPEG 2000 format being shot down by a patent claim? Is there a good alternative to the format?

Re: [JPP-Devel] Open (File) Plugin
Paul, I agree with Michael. These seem like logical changes. Any time we can separate the GUI from the underlying model it is a good thing. Does anyone see any problems with the changes Paul described? Perhaps you could work up some code, maybe just interfaces, and let us take a look? Thanks, The Sunburned Surveyor P.S. - You siad that "The OpenFilePlugins would be registered in the registry and would have a description and list of supported file types that could be used by the main Open file plugin to generate the list of formats in the drop down." What happens when more than one OpenFilePlugin is registered for the same file type?
