The SEDRIS Data Representation Model
APPENDIX A - Classes Source |
|---|
An instance of this DRM class specifies a description of a source or intermediate dataset used during data generation. The term "source" is used loosely, and covers intermediate forms and final products as well as the original data sources.
Description of a VPF database used as a source of feature information.
This class provides a mechanism for documenting the sources used in environmental database generation. It can also be used to document intermediate forms of the data, as well as final products. In conjunction with the <Process Step> 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 uses a <Citation> component to refer to the source data, so it has the flavor of a bibliographical reference, and can be used to refer to books, maps, presentations, or any other type of 'publication', as well as to digital data sets. Each <Source> instance includes a field in which the nature of the contribution of each source to the result can be described.
| SE_String | description; | (notes) |
|---|---|---|
| SE_Integer_Positive | scale; | (notes) |
| SE_String | contribution; | (notes) |
This is a citation for the source data set.
This is the time period described by the source data set.
The description field specifies a description of the source data set, and is mandatory.
The scale field specifies the scale of the source data set (for example, 24000 for a "1:24,000" scale).
If supplied, the contribution field states what the source data set contributes to the result.
