I searched exhaustively over the internet as well as at this Exporting Symbology from ArcGIS for Desktop to Microstation or QGIS? but didn't find a satisfactory answer. Hope to get the answers from the experts over here.
Suppose I have styled a polygon shapefile (e.g.: Border width = 0.26, border color = green, red colored simple fill, label displayed, etc ). When I save the style in QGIS, it is saved in XML format which is specific only to QGIS. Same is the case with other software which they store it in their own format. Which means, I cannot exchange styling information between different software.
Though the OGC SE standard is in place, I was just confused why this is not being implemented by any software. QGIS 1.8 supports SLD but then what is the purpose of storing the style as QGIS specific .qml file ?
Also, since SLD standard is used for web-services, is it OK to use this standard in this case (for exchanging data between different software)?
