In this paper, we describe the functionality of a toolkit for sharing and long-term use of different types of geological data sets across disciplines. Our tools allow users to describe the meaning of their data by attaching semantic information to it. The toolkit also makes use of the users? access patterns to learn how the data are used to further enhance the utility of data centric methods. These learned patterns are used in conjunction with the semantic data to help other users find common ways to navigate heterogenous collections and highlight interesting information. Our current prototype is being developed in close collaboration with the Metamorphic Petrology working group formed to facilitate sharing of data within this subdiscipline of geosciences as well as with other systems for sharing of geological data.
