Layer Metadata

formatted metadata attributes of a given vicmap layer (vicmap_query(layer)). Metadata is retrieved from the Vicmap catalogue. data_citation() prints a BibTex style citation for a given record; similar to base::citation(). data_dictionary() returns a table with names, types and descriptions of the data within the selected layer (see details). get_metdata() returns a list with three elements, containing metadata, the data dictionary and the url of the metadata for the record.

data_citation(x = NULL, metadataID = NULL)

data_dictionary(x = NULL, metadataID = NULL)

get_metadata(x = NULL, metadataID = NULL)

Arguments

x

Object of class vicmap_promise (likely passed from vicmap_query())

metadataID

character: ID of data (useful if data is not available through WFS)

Value

citation, data.frame or list
