A citable unit of any kind is identified by a URN and has a human-readable label.

Value for the CitableTrait for discrete objects.

Value for the CitableTrait for citable text content.

Abstraction of values for a citable trait.

Define default value of CitableTrait as NotCitable.

Value for the CitableTrait for everything not citable.

Value of the UrnComparisonTrait for evertything that can NOT be compared using URN logic.

Unique identifiers expressible in the syntax of the IETF's URN specification.

Value of the UrnComparisonTrait for evertything that can be compared using URN logic.

Abstraction of values for URN manipulation.

Define default value of UrnComparisonTrait as NotUrnComparable.

All subtypes of Urn are URN comparable.

Override Base.== for all Urn types.

==(u1, u2)

Urn subtypes should implement addversion(urn::U, versionid)::U.

Citable content should implement cex.

cex(, obj; delimiter)

Citable text content should implement cex.

cex(, txt; delimiter)

It is an error to invoke the cex function on material that is not citable.

cex(, x; delimiter)

Delegate cex to specific functions based on type's citable trait value.

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")

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

Urn subtypes should implement dropversion(urn::U)::U.

Delegate fromcex to specific functions based on type's citable trait value.

fromcex(s, T; delimiter)

Citable content should implement label.

label(_, obj)

Citable text content should implement label.

label(_, txt)

It is an error to invoke the label function on material that is not citable.

label(_, x)

Delegate label to specific functions based on type's citable trait value.

parts(componentString)

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

Examples

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

Citable content should implement cex.

urn(_, obj)

Citable text content should implement urn.

urn(_, txt)

It is an error to invoke the urn function on material that is not citable.

urn(_, x)

Delegate urn to specific functions based on type's citable trait value.

urn(x)

URN-comparable objects must implement urncontains.

URN-comparable objects must implement urnsimilar.
