The 'Procedure' package provides a concrete implementation of the abstract OM_Process class (from ISO 19156).<br/><br/>The implementation is intended to support the following requirements:<br/>1) reference to supporting documentation (attribute "documentationRef"); e.g. online documentation describing the procedure in detail;<br/>2) specification of parameters that remain fixed within a particular configuration of the procedure (Configuration); a soft-typed approach is used here following the pattern adopted for OM_Observation/parameter;<br/>3) specification of the resolution [1] with which each observed physical phenomenon is measured; and<br/>4) specification of the measuring interval [2] of the instrument or sensor for each observed physical phenomenon.<br/><br/>[1] Resolution: smallest change in a quantity being measured that causes a perceptible change in the corresponding indication (from the 'International vocabulary of metrology' [http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2008.pdf])<br/>[2] Measuring interval: set of values of quantities of the same kind that can be measured by a given measuring instrument or measuring system with specified instrumental uncertainty, under defined conditions (from the 'International vocabulary of metrology' [http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2008.pdf])<br/>
