Create a schema for a Darwin Core Archive

A schema is an xml document that maps the files and field names in a DwCA. This map makes it easier to reconstruct one or more related datasets so that information is matched correctly. It works by detecting column names on csv files in a specified directory; these should all be Darwin Core terms for this function to produce reliable results. This function assumes that the publishing directory is named "data-publish". This function is primarily internal and is called by build_archive(), but is exported for clarity and debugging purposes.

Usage

use_schema(overwrite = FALSE, quiet = FALSE)

Arguments

overwrite

By default, use_schema() will not overwrite existing files. If you really want to do so, set this to TRUE.

quiet

(logical) Should progress messages be suppressed? Default is set to FALSE; i.e. messages are shown.

Value

Does not return an object to the workspace; called for the side effect of building a schema file in the publication directory.

Details

To be compliant with the Darwin Core Standard, the schema file must be called meta.xml, and this function enforces that.

See also

build_archive() which calls this function.

if (FALSE) { # \dontrun{
use_schema()
} # }
