Software developers complain about wrong data. It just does not comply to the specs. It is a complete mess. The owners of the data do not understand the agitation because they have worked with some odd, old software for ages and it sort of always worked out. Why change now? The meta of the data sits in the mind of so many people but has never been organized and fixed (to fit into your software). The Data Monger on the other hand has the same problems but the other way round. The data does not download, the encoding is wrong, the coordinate system is screwed and at the end all the decimals are cut off. Who is right? It is always the data owner! Because software comes and goes, the data stays. This talk is a plea to mind the data. Remember this: Never use software that does not work on open formats. Really open. Like in Open Source but even better. Arnulf Christl (Metaspatial)
