Create a dm object from an XML version of the Swiss Register of Plant Protection Products
Source:R/srppp-xml.R
srppp_dm.RdWhile reading in the data, the information obtained from the XML file is
left unchanged, with the exceptions listed in the section 'Details'.
An overview of the contents of the most important tables in the resulting
data object is given in vignette("srppp").
Usage
srppp_dm(from = srppp_xml_url, remove_duplicates = TRUE)
# S3 method for class 'srppp_dm'
print(x, ...)Value
A dm::dm object with tables linked by foreign keys pointing to primary keys, i.e. with referential integrity. Since version 1.1, the returned object has an attribute named 'culture_tree' of class data.tree::Node.
Details
Corrections made to the data
In the following case, the product composition is corrected while reading in the data: The active substance content of Dormex (W-3066) is not 667 g/L, but 520 g/L This was confirmed by a visit to the Wädenswil archive by Johannes Ranke and Daniel Baumgartner, 2024-03-27.
Removal of redundant information
Information on products that has been duplicated across several products sharing the same P-Number has been associated directly with this P-Number, in order to avoid duplications. While reading in the XML file, it is checked that the resulting deduplication does not remove any data.
In very few cases of historical XML files, there are two
<Product>sections sharing the same W-Number. In these cases, one of these has apparently been included in error and an informed decision is taken while reading in the data which one of these sections is discarded. The details of this procedure can be found in the source code of the functionsrppp_xml_get_products.
Amendments to the data
In the table of obligations, the following information on mitigation measures is extracted from the ones relevant for the environment (SPe 3).
"sw_drift_dist": Unsprayed buffer towards surface waters to mitigate spray drift in meters
"sw_runoff_dist": Vegetated buffer towards surface waters to mitigate runoff in meters
"sw_runoff_points": Required runoff mitigation points to mitigate runoff
"biotope_drift_dist": Unsprayed buffer towards biotopes (as defined in articles 18a and 18b of the Federal Act on the Protection of Nature and Cultural Heritage) to mitigate spray drift in meters
