Conservation or Heritage science makes use of a wide range of analytical processes to examine, measure, and identify objects and the materials that they are composed of. The data gathered can range from a simple number to a complex multi-dimensional data array or images and spectra. In this section the generic relationships and events involved in all these processes have been broken down into stages, represented by a few specific examples. For more complex forms of analysis several of these stages would need to be joined together and, in some cases, this would need to be done several times. In the schematic diagrams shown in this section the term Dimension has been used to cover all types of single or groups of measured values, from simple widths and heights to more complex spectra and 3D data cubes. In addition, to allow the definition of further relationships the CIDOC CRM term Information Object has also been used to represent data sets as a whole.
