yeah, it should you can add it manually and test if this interferes w/ current readers (OJ,GDAL), but it really should not.
wrt. the srsName, a srsId would be easier to parse, as we only support EPSG codes anyway or don't we? also, while we are at it we could think about a general metadata tag, for more other future meta data eg. creator names, dates or whatever. this could go similar to the way java2xml serializes data. <metaData> <entry> <key class="java.lang.String">some number</key> <value class="java.lang.Integer">754</value> </entry> ... </metaData> all that said, yes it should be backward compatible w/ readers, but would not syntax parse as a valid gml document anymore, hence we would have to get rid of the 'xmlns:gml="http://www.opengis.net/gml";' header entry. ..ede On 23.11.2017 10:35, Rahkonen Jukka (MML) wrote: > Hi, > > So could it work simply by adding srsName as an attribute into > featureCollection: > > <?xml version='1.0' encoding='UTF-8'?> > <JCSDataFile xmlns:gml="http://www.opengis.net/gml"; > xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"; > > <JCSGMLInputTemplate> > <CollectionElement>featureCollection</CollectionElement> > <FeatureElement>feature</FeatureElement> > <GeometryElement>geometry</GeometryElement> > <ColumnDefinitions> > </ColumnDefinitions> > </JCSGMLInputTemplate> > > <featureCollection srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";> > <feature> > <geometry> > <gml:Polygon> > <gml:outerBoundaryIs> > <gml:LinearRing> > <gml:coordinates>474.0,371.0 > 620.0,380.0 > 520.0,280.0 > 474.0,371.0 </gml:coordinates> > </gml:LinearRing> > </gml:outerBoundaryIs> > </gml:Polygon> > </geometry> > </feature> > > </featureCollection> > </JCSDataFile> > > > -----Alkuperäinen viesti----- > Lähettäjä: [email protected] [mailto:[email protected]] > Lähetetty: 22. marraskuuta 2017 23:35 > Vastaanottaja: [email protected] > Aihe: Re: [JPP-Devel] SRID support in JML > > Jukka, > > adding to the XML structure will be ignored by current readers. changing the > structure would break things. > > ..ede > > On 11/22/2017 21:41, Rahkonen Jukka (MML) wrote: >> Hi, >> >> In GML srsName is set for each feature.
