How to convert the apple address book to RDF

These tools exist to do it:

• ​Richard Newman's python converter. there is an ​older version
• ​AB-FOAF by Olivier Gutknecht - a cocoa / python program.
• ​XML-FOAFKnows-FromvCard by KjetilK. Does only foaf:knows creation

• ​Addressbook reference

An applescript file that does a starting thing

tell application "Address Book"
	set out to "<rdf:RDF xmlns:foaf='http://xmlns.com/foaf/0.1/' xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'>"
	repeat with p in people
		set out to out & "<foaf:Person>"
		set out to out & "<foaf:name>" & (name of p) & "</foaf:name>"
		repeat with e in emails of p
			set out to out & "<foaf:mbox>mailto:" & value of e & "</foaf:mbox>"
		end repeat
		set out to out & "</foaf:Person>"
	end repeat
	set out to out & "</rdf:RDF>"
	out
end tell

The DataSource itself

It should copy/paste from the RDF-File datasource: source:trunk/gnowsis/src/org/gnowsis/adapters/rdffile/RDFFileDataSource.java

I uploaded a script I made a couple of years ago, but it's appeared as 0 bytes. So here's the script.

property foaf : "FOAF"

tell application "Address Book"

set m to properties of my card

set the_file to (((path to desktop) as string) & first name of m & last name of m & ".rdf") as file specification set rdf to "<rdf:RDF" & return set rdf to rdf & "xmlns:rdf=" & quote & "​http://www.w3.org/1999/02/22-rdf-syntax-ns#" & quote & return set rdf to rdf & "xmlns:rdfs=" & quote & "​http://www.w3.org/2000/01/rdf-schema#" & quote & return set rdf to rdf & "xmlns:foaf=" & quote & "​http://xmlns.com/foaf/0.1/" & quote & return set rdf to rdf & "xmlns:admin=" & quote & "​http://webns.net/mvcb/" & quote & ">" & return set rdf to rdf & "<foaf:Person rdf:nodeID=" & quote & "me" & quote & ">" & return set rdf to rdf & "<foaf:name>" & first name of m & " " & last name of m & "</foaf:name>" & return if nickname of m ≠ "" then

set rdf to rdf & "<foaf:nick>" & nickname of m & "</foaf:nick>" & return

end if

if group foaf exists then

repeat with this_person in every person of group foaf

set rdf to rdf & "<foaf:Person>" & return set rdf to rdf & "<foaf:name>" & first name of this_person & " " & last name of this_person & "</foaf:name>" & return repeat with e in emails of this_person

set rdf to rdf & "<foaf:mbox>mailto:" & value of e & "</foaf:mbox>" & return

end repeat if ((count of urls of this_person) > 0) then

if label of url 1 of this_person is "FOAF" then

set rdf to rdf & "<rdfs:seeAlso rdf:resource=" & quote & value of url 1 of this_person & quote & "/>" & return

end if

end if set rdf to rdf & "</foaf:Person>" & return

end repeat

end if

set rdf to rdf & "</rdf:RDF>"

end tell

try

open for access the_file with write permission set eof of the_file to 0 write (rdf) to the_file starting at eof close access the_file

on error

try

close access the_file

end try

end try
