Parse a single GeoNetwork link element

Source: R/read_metadata.R
parse_gn_link.Rd

GeoNetwork often encodes links as a single string separated by |, e.g.: |Darstellungsdienst (WMS)|https://...|OGC:WMS|||. This helper splits such a string into named columns and pads missing parts up to 6 elements.

Usage

parse_gn_link(x)

Arguments

x

Character string as found inside a <link> XML node.

Value

A one-row tibble with columns:

  • link_name

  • link_desc

  • link_url

  • link_protocol

  • link_mime

  • link_order

Details

The order used here is:

  1. link name

  2. link description

  3. link URL

  4. link protocol (e.g. "OGC:WMS")

  5. MIME type

  6. order

Note: In many Berlin GDI records the first field (link name) is empty, and the actual meaningful text is in the second field (description).

Examples

parse_gn_link("|Darstellungsdienst (WMS)|https://example.org/wms?|OGC:WMS|||")
#> # A tibble: 1 × 6
#>   link_name link_desc                link_url link_protocol link_mime link_order
#>   <chr>     <chr>                    <chr>    <chr>         <chr>     <chr>     
#> 1 ""        Darstellungsdienst (WMS) https:/… OGC:WMS       ""        ""
