2.4.2.3 Inverse Functional Identifier section contains broken link to FOAF Vocabulary Specification web page

[MartinKoob]

In the last sentence of the Rationale paragraph of section 2.4.2.3 Inverse Functional Identifier there is a link to a document describing the FOAF principle.

which are loosely inspired by the widely accepted FOAF principle (see: Friend Of A Friend).

That link only opens a page with one line of text that says the following.

Temporarily, please see /foaf/0.1 document.

Opening that link goes to the page with the specification.

FOAF Vocabulary Specification

Namespace Document 1 May 2004

This document contains an alert stating there is a more recent release from 2014.

Status of This Document

ALERT! We are currently serving an older version of the FOAF spec, from 2004, while restoring from archives. Although it did not change radically between 2004 and 2014 (last release), please consult the Internet archive ( html, rdf) for that and earlier releases, which extend back to our earliest version in 2000.

There are a couple of other URLs based on the http://xmlns.com/foaf/spec/ URL that also need to be modified:

• mbox
• mbox_sha1sum.

SUGGESTED RESOLUTION:

• The link in the Rationale paragraph of Section 2.4.2.3 should be updated to either http://xmlns.com/foaf/0.1/ or the location of the 2014 release* of the Friend of a Friend Vocabulary Specification.
• The links for the properties from the FOAF Spec listed above be changed to the the ones based on the http://xmlns.com/foaf/0.1/ URL or on based on the location of the 2014 release of the FOAF spec.

* I tried a few searches to locate this more recent 2014 release. I found references to it but I could not find a URL for the actual release.     - https://en.wikipedia.org/wiki/FOAF
