Agreed. There are a number of reasons to define a Derived Dataset as something that contains additional original input and not as the same dataset processed automatically into some other format. 1) It avoids people having to share tedious numbers of large datasets that are slightly different from the last one and may have been used to produce a product with a very short life-expectancy anyway. 2) It clarifies that people don't have to expose proprietary storage, indexing, analysis or manipulation techniques unless they want to. My company does not support a licence that allows people to see how we store data internally, it is going to be hard enough to stay ahead of the free-software movement without exposing all ones secrets at the outset! 3) The core reason for the share-alike element for this project in the first place is to ensure that people share their knowledge about where features are and share corrections to this dataset. 4) Because if people don't want to expose their internal data formats then they only have to combine the OSM data with some other dataset to create a Collective Work and then they don't have to expose anything further downstream in their processing anyway. To be clear, is anyone fighting for a licence that does require users of the data to expose all their analysis and manipulation software techniques even when no new facts or corrections have been made to the OSM dataset? If no one wants that then I am sure the licence can be constructed so that it isn't necessary.
