GALE

David Smits, Paul De Bra
2011 Proceedings of the 22nd ACM conference on Hypertext and hypermedia - HT '11  
This paper presents GALE, the GRAPPLE Adaptive Learning Environment, which (contrary to what the word suggests) is a truly generic and general purpose adaptive hypermedia engine.  ...  GALE takes the notion of general-purpose a whole lot further.  ...  Finally we discuss related work, some of which suggests future developments in adaptive hypermedia as we realize that no matter how generic GALE is a new and more generic generation of adaptation engines  ...

Each of these factors must be considered when interpreting the compositional variations in a set of sedimentary rocks.
