Class Name: Process
Subclasses
This DRM class is concrete and has no subclasses.
Definition
An instance of this DRM class describes a processing step performed
during the generation of the environmental data set being represented.
The process of can be described at different levels of detail, ranging
from a single high-level process to a complex network of processing
steps. However, only a single level of detail is supported
(i.e., processes can not be described hierarchically).

Example
- Filtering of feature data based on FACC feature code using ARC / INFO.
- Polygonalization of feature data using S1000.
FAQs
- What is the purpose of this class?
- This class provides a mechanism for documenting the processes used in
environmental database generation. In conjunction with the
<Source> class, this class can be used to construct
a network-like description of the database generation process, consisting
of processing steps linked by their input and output data. This class
allows the date and time that each process was performed to be recorded,
as well as a point of contact for each processing step. Each
<Process> can be associated with a collection of
<Sources>, each of which is labeled as being either
an input or an output. Thus each <Process> may use
multiple inputs and produce multiple outputs. At a minimum, the overall
database generation process (e.g. SOF ATS) should be identified.
