The SEDRIS Data Representation Model
APPENDIX A - Classes Process Step |
---|
An instance of this DRM class specifies information about an event in the creation process for the data specified by the scope.
Filtering of feature data based on FACC feature code using ARC / INFO.
Polygonalization of feature data using S1000.
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 Step> instance can be associated with a collection of <Source> instances, each of which is labeled as being either an input or an output. Thus each <Process Step> instance may use multiple inputs and produce multiple outputs. At a minimum, the overall database generation process (such as SOF ATS) should be identified.

For a given instance of <Source> to which the given <Process Step> instance is associated, the following hold. - If the given <In Out> instance's input field is SE_TRUE, the <Source> instance represents a data set used in the event represented by the given <Process Step> instance. - If the given <In Out> instance's input field is SE_FALSE, the <Source> instance represents an intermediate data set that (1) is significant in the opinion of the data producer, (2) is generated in the processing step represented by the given <Process Step> instance, and (3) is used in later processing steps.
This specifies the date and time (or range of date and time) on or over which the event represented by the given instance of <Process Step> occurred.
If provided, these instances of <Responsible Party> provide identification of, and means of communication with, person(s) and organization(s) associated with the given instance of <Process Step>.
The description field specifies an explanation of the event, including related parameters or tolerances.
If supplied, the rationale field states the requirement or purpose for the given <Process Step> instance.
