get_attributes
Arguments
- x
an "attributeList" element from an emld object
- eml
The full eml document, needed only if <references> outside of attributes must be resolved.
Value
a data frame whose rows are the attributes (names of each column in the data file) and whose columns describe metadata about those attributes. By default separate tables are given for each type
Details
EML metadata can use "references" elements which allow one attribute to use metadata declared elsewhere in the document. This function will automatically resolve these references and thus infer the correct metadata.
Examples
f <- system.file("tests", emld::eml_version(),
"eml-datasetWithAttributelevelMethods.xml", package = "emld")
eml <- read_eml(f)
get_attributes(eml$dataset$dataTable$attributeList)
