Override Base implementation of show.

Catch-all function for addversion method.

addversion(u, s)

components(uString)

Splits a string on colons (separator for top-level components of URNs).

Examples

julia> components("urn:cts:greekLit:tlg0012.tlg001.msA:1.1")

components(u)

Splits a URN's string representation into top-level components.

Catch-all function for dropversion method.

dropversion(u)

parts(componentString)

Splits a string on periods (seprator for parts within components of URNs).

Examples

julia> parts("tlg0012.tlg001.msA")

validurn(s)

True if s is valid for this type of URN.

This checks only the minimal generic syntax for a URN, and should be overriden to check more specific requirements of types extending URN.

Examples

julia> validurn("urn:isbn:1788998367")
