For example, a Folder has no !InputStream, no byte size, etc. I think !DataSources and Folders are really something different. They surely do share characteristics (they both have a URI and metadata) but this should be expressed by their super type. One should not inherit from the other.

     81Leo: Ok, still an important use case of gnowsis is not covered: structured crawling. We often need the user to select "which folders are now to be crawled" or the user wants to "see" what there really is in the datasource, without having to crawl it completely first. So I suggest to make another interface, independent of the existing DataCrawler, that ALLOWS to "peek" into the datasource, IF it is hierarchical. 
     82This interface I called ApertureHierachicalAccess and is described there.
