Re: [JPP-Devel] R: Make OpenJUMP to read GML2 with schema saved from WFS 1.0.0
Hi, Yes there is and I have it installed. However, I would not recommend it for others. It is even a bit hard to find the deegree plugin. I am not sure if our wiki has these links http://wiki.deegree.org/deegreeWiki/deeJumpPlugin http://wiki.deegree.org/deegreeWiki/OpenJumpPackages The GML adapter works fine. However, you need to install quite a lot additional stuff for making it to work. The WFS-plugin that must be installed as well is not maintained and unfortunately does not really work any more with current WFS servers. WMS GetFeatureInfo tool is useful but it does not work with very many WMS servers (server configuration issue mostly) and GetFeatureInfo requests do not work through https and basic authentication even with normal WMS use it is OK. Easiest way to get the GML read support is to install OpenJumpPackage but latest one is a bit old with OpenJUMP version: svn revision 2165. It looks like everything in OpenJUMP that came from deegree project is effectively unmaintained at the moment. -Jukka Rahkonen- Giuseppe Aruta wrote: There must be a deegree plugin to read GML2, I think.

Re: [JPP-Devel] Make OpenJUMP to read GML2 with schema saved from WFS 1.0.0
Hi Martin, I just get frustrated every now and then with WFS and GML. It is so simple to get for example the railways from WFS with http://188.64.1.61/cgi-bin/tinyows?service=wfsversion=1.0.0request=GetFeaturetypename=lv:mml_railway I can see the GML on screen and it looks pretty understandable with all the attributes and geometries. With a pencil and cross-ruled paper I could even draw the geometries. Then I save the result on disk and believe that everything is OK and I have received a nive set of geospatial data. But actually there are not very many free GIS software being able to open and show the data that was saved on a disk. Schema is missing (nobody told it should have been loaded as well, and the link to schema inside GML does not help you much when on the field off-line), gml cannot be parsed and so on. What have we done to deserve these standards? Not to mention the advanced axis order frustration with WMS 1.3.0, WFS 1.1.0, WCS 1.1 and GML3. Situation with open source WFS clients is actually rather good now, finally. OpenJUMP does not work any more (or it may with deegree servers but not with others) but Kosmo GIS, gvSIG, QGis and iGeoDesktop are usable as well as uDig and OpenLayers. And for me it is not so big trouble to convert GML from disk into other formats with OGR. However, I would like to teach others to do it in some extremely simple way and not through additional downloads and command line workarounds. Nowadays people tend to give in or escape immediately when they see an open command window. -Jukka Rahkonen- Martin Davis wrote: Jukka, I may be mis-understanding your post, but the difficulty with reading GML2 from WFS is the same as reading arbitrary GML2: GML schemas can be very complex, and thus it's very difficult to develop a general-purpose GML2 Reader.

Re: [JPP-Devel] Make OpenJUMP to read GML2 with schema saved from WFS 1.0.0
If all those other platforms are able to handle WFS reasonably well, that seems to take the wind out of my statement that GML is too hard to implement! Perhaps some of them are implementing a sane subset of GML, which would be easier to implement. I suspect there's an 80-20 situation here, where most WFS servers are only serving up fairly straightforward GML. (Seems like you still need to parse the schema, though, which is hard to see how that could be made simple). It would be nice to look at the implementations, and follow whichever one looks easiest for OJ as well. But in general I share your frustration about GML. It originally seemed like the answer to an open spatial format standard, but the complexity of it is a huge barrier to entry. (In my wilder moments I daydream that It would be nice if the open-source geospatial world got together to define a new standard format which would be more practical to implement.!)

Re: [JPP-Devel] Make OpenJUMP to read GML2 with schema saved from WFS 1.0.0
Hi, I suppose those clients are all using either geotools, deegree of ogr internally but I am not sure. Somehow I feel that Geotools might suit OpenJUMP but I am not a developer but just a user. Reading GML is not the biggest problem with WFS any longer. Some programs may not know what to do with some data types, like xs:short or xs:long. Some may forget to initialize the attribute table with all the attributes which included in the schema if the first record in the GML part does not contain all the attributes and so on but there are less and less pure parsing errors. Biggest troubles seem to be now with WFS 1.1.0 and GML3 and the axis order. There cannot be a single software in the world handling all the cases correctly. Nor a single person who can say how they really should behave. Axis order trouble reflects to building correct spatial filters, which seems to be difficult to do in such a way that all different WFS servers accepts them even with coordinate systems like UTM which do not suffer from the axis order mess. Even adding a bounding box into GML3 filter can lead to failure because there are ridicuosly many ways to do it. I feel that WFS 1.0.0 with GML2 was still a relatively simple and usable standard. Unfortunately nobody cares to correct the remaining troubles with it because there are versions 1.1.0 an 2.0.0 around and those are requirement for the Inspire datasets, for example. There must be new troubles to come with application schemas (instead of simple feature ones) and things like real GML3 curves etc. Some WFS servers can deliver data also in other formats than GML. It is allowed, but as you wrote, a really good alternative is missing. Shapefiles with geometry type limitation and short field names etc. are not at all ideal and I suppose that Geojson is not featurerich enough. -Jukka Rahkonen- Martin Davis wrote: If all those other platforms are able to handle WFS reasonably well, that seems to take the wind out of my statement that GML is too hard to implement!
