Availability::- use_module(library(semweb/rdf_db)).
rdf_register_ns(+Alias, +URL)
Same as rdf_register_ns(Alias, URL,[]).
rdf_register_ns(+Alias, +URL, +Options)
Register Alias as a shorthand for URL. Note that the registration must be done before loading any files using them as namespace aliases are handled at compiletime through goal_expansion/2. If Alias already exists the default is to raise a permission error. If the option force(true) is provided, the alias is silently modified. Rebinding an alias must be done before any code is compiled that relies on the alias. If the option keep(true) is provided the new registration is silently ignored.
