Keyword system used in the EIS
Data sets in the EIS have been assigned the lowest level of keywords possible. This, together with a hierarchical structure, facilitates 'smart' searching. For example, searching on the broad term 'vertebrate' will automatically find any data set assigned the keyword 'bird', 'fish', 'mammal' etc or any subset of those keywords.
There are 40 top-level 'themes' which are then broken down into 'concepts' or keywords.
Click on any theme to see the keywords which fall under that theme.
