Finding a model needed for a particular purpose is facilitated by various forms of search. A free-form search into the knowledgebase is provided by the search bar in the upper-right corner of the user-interface. This links to knowledge contained within the triple-store knowledgebase, largely independent of semantic context. Other more directed, semantically-driven searches are available from the search page. Links between specific categories of knowledge and models available within the server are contained here. To accomodate this, specific models are tagged and allocated to specific environmental categories. This is aided by the application of ontologies such as SWEET (Semantic Web for Earth and Environmental Terminology from http://sweet.jpl.nasa.gov).
