DESCRIPTION
This is a plugin for RDF::Query providing a number of extension
functions.
*
http://buzzword.org.uk/2011/functions/gb#postcode_valid
Given a literal, returns a boolean indicating whether it seems to be
a syntactically valid UK postcode.
*
http://buzzword.org.uk/2011/functions/gb#postcode_format
Given a literal, if it seems to be a valid UK postcode,
canonicalises the formatting; otherwise returns the literal
unscathed.
*
http://buzzword.org.uk/2011/functions/gb#telephone_valid
Given a literal, returns a boolean indicating whether it seems to be
a number that could be dialed from a UK phone.
Only the digits '0' to '9', letter 'x' (extension) and '+'
(international dialing code) are expected. Other characters are
stripped out before any checks.
*
http://buzzword.org.uk/2011/functions/gb#telephone_format
Canonicalises the formatting of a phone number that is valid. Should
return invalid phone numbers unscathed.
*
http://buzzword.org.uk/2011/functions/gb#telephone_std
Returns the STD code for a phone number, if it could be extracted;
the empty string otherwise.
*
http://buzzword.org.uk/2011/functions/gb#telephone_local
Returns the local part of a phone number, if it could be extracted;
the empty string otherwise.
*
http://buzzword.org.uk/2011/functions/gb#telephone_extension
Returns the extension from a phone number, if it could be extracted;
the empty string otherwise.
*
http://buzzword.org.uk/2011/functions/gb#telephone_uri
Returns a phone number as a <tel:> URI.
An existing <tel:> URI should pass through unscathed.
