I've sometimes wondered if it wouldn't be necessary to create the OpenJUMP project on sourceforge or on other forges, because it would be confusing if someone else decided to create an OpenJUMP project now... sf.net for sure is product centric... but i won't change a running system until there is need. if somebody opens an(other) openjump project we have to deal with it anyway, if on sf.net or somewhere else :) About copyright, I agree that the code base does not follow clear rules and it would need a serious clean up, but I can't see clearly what the real problem is and why we should have to waive our copyright to an organization to be serious. me neither, all modifications to oj's java is based on gpl code and hence automatically copyleft. we should rather cleanup the gpl header and enforce it's usage especially for new files, so it is clear the respective copyright holder makes it copyleft by contributing. I'm pretty attached to copyright, because I feel like having my name associated with the code I wrote is about the only way to get a little recognition for the work in the long run. theoretically every author would have to be mentioned. as this is practically an issue especially with old core code i'd vote to add author tags to javadoc method comments and such but keep the header clean. for initially created classes and code i am fine with a author's note in or below the header. Morover, I think OpenJUMP is still very small to spend time in administration tasks. But it can change quickly. So, let's see what will happen this year. Exactly my point, lot's of bugs and featreqs laying around unresponded because a fistful of volunteers is not enough. And let's hear Stefan, Ede and other members. As far as licensing is concerned, I'm afraid my 2 cents is only 1 cent. So in conclusion: - we should streamline the header (i'd like to make it smaller if possible) - add it to _all_ files e.g. start scripts (or at least a note regarding licensing) - negotiate a way how authors tag their code, if they want to Everything else is beyond our current scope i think. As promising the idea of JPP as an umbrella like Apache Project sounds, i really don't see our group in any shape near that. I don't have objections to the name though, if we decide to keep calling us like that and the product OpenJUMP that's fine with me. ..ede Michaël First I want to talk about JPP versus OpenJUMP. Then I want to talk about copyright on OJ code. I'm still kind of attached to the Jump Pilot Project name, since that's what we used long ago when this all got started. I think it is important to remember that the Jump Pilot Project is technically the software project set-up to coordinate work on a number of JUMP forks. I view OpenJUMP as the product of that software project, not the project itself. That may not seem like an important distinction, but I could see the JUMP Pilot Project being set-up at some future point to help maintain JTS or JCS or other software related to OpenJUMP. For many months I've wanted to use some of the JUMP code to set-up a Geotools like library for OpenJUMP's simple feature model, which is simply the best I've ever seen implemented in code. I haven't had the time to do that yet, but I can see that being another product of the JPP. Apache is the organization that produces the Ant build tool. In a similar way, the JPP produces OpenJUMP. If you've been around long enough, you'll remember when we had the JPP, but OpenJUMP was just had a code base without a name. :] I know not everyone involved in development now has been around long enough to know all this, but I do think they are important details. As far as the copyright notice goes, I think we are a little bit sloppy with how we handle it. I'd prefer not to have a copyright notice at all, rather than a copyright notice done improperly. This get's especially tricky in OpenJUMP since we can have so many contributors working on a single class. It seems like most serious open source projects make you sign a copyright waiver before you contribute code. That is how I would prefer we handle copyright:You waive your copyright to contribute. If that makes people uncomfortable, I think we should have an opt-out system for copyright waiver. In this scenario you would specifically reserve copyright when you think your code is important and unique enough. We'd then have to track that. FYI: This sort of system will make it easier if we ever decide to formalize OpenJUMP as a non-profit. If we really want to handle this properly we should think about making OpenJUMP an OSGeo project or making the JPP a project of the Free Software Conservancy (http://sfconservancy.org/).

[JPP-Devel] Keyboard shortcut disturbs the pan tool
Hi, Try this: - Have a map open in map window and pan a few times with the hand tool - Zoom in or out with the keyboard Alt-Mouse click shortcut - Relaese alt button and continue panning with the hand tool It is hard to define what happens but usually the map jumps oddly with the first click and drag panning. It feels like the control is not totally returned for the pan tool but something from the zoom operation is held in memory. This is most easy to see by zooming in the centre of the map but starting the panning near the border. Tested with Windows XP, jre 1.6.0_29 and OJ 1.4.3 Plus from a few days ago. -Jukka Rahkonen- -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/___ Jump-pilot-devel mailing list Jump-pilot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel

What if the method calls another method copyrighted by Stefan? How do our copyright's impact the copyright of Vivid Solutions on the original class? What if Ede rewrites my method? How much of a rewrite is needed to make the method subject to his copyright and not mine? What if the method does basically the same thing, but in a slightly different way? that's all interesting but leading away from the issue: the difference between copyright and licensing. even if i hold the copyright on some code, if i licensed it under GPL to somebody i lost control over it as long the licensee honors the GPL terms. so there is no need to waive anything. This all gets cloudy pretty fast. I believe that is why most organizations that can afford the legal advice ask for a copyright waiver. bigger projects/organization often like you to waive so they can act as copyright holder in legal disputes. that's fine but no help to us at all as we would need all contributors to OJ codebase have to sign a waiver which is impossible as we wouldn't probably know all or find a contact to everybody. If we had done this in the beginning, there would only be one copyright holder to worry about, Vivid Solutions. yep, but we didn't and so it is. At the end of the day, it probably doesn't matter a great deal, because we've gotten so many contributions over the years from so many people that are no longer involved in the project. I have no idea how you would get all of them to waive copyright. (Can you quite title to code copy right retroactively?) exactly my point. Anyhow, I think adding our own personal copyright statements to headers of source code files is a bad practice. But that is just my 1 cent. :] I'll keep contributing to OpenJUMP either way. see my other mail about that.

Now you are talking about trademark protection. Again, this is something a more formal non-profit would handle. We'd need to elect some directors of the non-profit, who would decide how the trademark could be used. For example, my old OpenJUMP Blog might not be allowed. :] Not sure this is even necessary. Probably isn't going to be a huge conspiracy to steal the OpenJUMP name anytime soon. But it seems like a topic we have both thought about. Your comments are appreciated. My point is that there is a right way to handle copyrights and trademarks, and a wrong way. If we want to do it, we should do it the right way. let's not overengineer here. of course we could trademark the name, like somebody bought/pays for openjump.org ... but to what necessity. if someone really want's to sue away JPP or OpenJUMP, this someone probably will succeed and we simply use another one, the name is not our capital, the product is. imho. If we were curious, I can ask someone at the Free Software Conservancy if they could talk to us about the issues. As I mentioned before, I'm no expert. I'd love to see the JPP or OpenJUMP as an OSGeo Project, which would take care of these issues. That is a lot of work though. FYI: OSGeo expects projects to set-up a system for dealing with code copyright and to have rules and a governing body to handle questions about things like trademarks. let's keep it KISS ... maybe if someday a company sponsor or such decides to come on board it would be a good idea to formalize more. for now, KISS ;) ..ede Landon 2012/2/14 Michaël Michaud michael.mich...@free.fr: Hi Landon, Many things in your mail.

[JPP-Devel] WMS layer ordering goes to defaults
Hi, The WMS tool lets user to select many layers from WMS service at the same time. The selected layers are collected to the right side of the dialogue. There user can order the layers with the move up / move down arrows. This is important because OpenJUMP is finally sending a request for the WMS server to draw the layers in that order. Lets say there are layers orthophoto and markers. If the order in the request is orthophoto,markers the server will draw orthophoto on the bottom and markers above that which is fine. If order is markers,orthophoto the orthophoto will cover the markers and they will not show. Ordering of the layers works correctly in OpenJUMP but there is an issue: every time the Edit WMS query tool is opened again (from the WMS layer name - right click menu) the layers are ordered back to the default order (alphabetical?). It means that user needs to remember to order the layers again before pressing the OK button. It would be better to keep the edited order and show the list of selected layers accordingly when Edit WMS query is opened. -Jukka Rahkonen- -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Jump-pilot-devel mailing list Jump-pilot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel

[JPP-Devel] Editing shapefiles with SBN and SBX indexes
I just ran into an issue with SkyJUMP and I assume OpenJUMP (since our shapefile drivers are the same). When I add features to a shapefile layer that was created by ESRI and save changes, the SBN and SBX optional spatial index files are not updated (when present), This causes problems when viewing in ESRI-based software which assumes that the spatial indexes are up to date with their associated shapefiles. According to Wikipedia, these index files are not supported by any software except ESRI and are not strictly necessary. My testing seems to confirm that deleting them does no harm. I suggest that we check for the existence of shapefiles with.sbn and .sbx extensions (not to be confused with SHX database index files) and delete them as part of the process of writing or updating a shapefile. This should probably go at the end of com.vividsolutions.jump.io.ShapefileWriter.write.

Hi Larry, Jukka, Deleting index files when the .shp is written back to disk seems safe and easy.
