The Personally Identifiable Information (PII) Namespace

The initial issue of the namespace was on 2007-06-01.

On 1/14/2008 the Dublin Core Metadata Initiative announced "a set of editorial revisions to terms in the set of DCMI Metadata Terms", to synchronize syntax with their Abstract Model (DCAM). In the words of the late Lane Kirkland's late dad; "Never bet your bladder against the brewery and never argue with people who buy ink by the barrel.". That would be Editorial Boards. The RUSTPrivacy.org Marketing Department remains commited to offering the latest innovations, and everybody else will try like heck to keep their heads above the ink; brewer cooperation withstanding.

This document reflects DCMI usage as of 2008-01-14. Additional clarifications to the domain and range of elements in the namespace were added 2008-04-01 along with a formal accrual policy for new elements.

On 2008-06-18 the [aka] element was modified to have a range of Agent. This is the (reflective) identity element of the name space - as a token in a reference to a Bibliographic Resource, it replaces "any name for self". This is a major change and a new version for the [aka] element. For example, the text:"Ben Franklin, writing as Poor Richard, ...", means both 1) "Ben Franklin, writing as [aka], ..." and 2) [aka], writing as Poor Richard, ...", but also 3) "[aka], writing as [aka], ...". While a reference to a Bibliographic Resource need not be fully anonymous (3), care should be taken that only one name is telegraphed (1,2).

It was pointed out that all of the elements, of type rdf:Class, should start with a Capital Letter. Unfortunately all the elements were and are, rdf:Properties. This mistake has been rectified. The parties responsible; forced to subsist on Beer, Pizza and Cigarettes; are quite unaware they are being punished.

On 2008-08-08 the [image] element was added. This is an instance of [rdfs:range] <http://purl.org/dc/terms/Image> class, with the additional constraint that the Image, whatever form it takes, must identify at least one person, that is, it must contain Personally Identifiable Information.

XML Meta Data Profile (XMDP)

Term Reference

rel

HTML4 definition of the anchor tag rel attribute. This link points forward from the data (anchor) to term in the class of data (i.e. a term in the namespace).

rev

HTML4 definition of the anchor tag rev attribute. This link arcs backwards from the elements, list of valid terms, in the namespace to a specific instance of document data content, provided such an arc logically exists. In HTML, a "@rev" relation in the PII Name Space exists when the link identifies a person. Just because there is an anchor does not mean there is an arc to an identifying element, and this is never more true than in the case of PII - the "dots" are hardly to blame when they lack a connection.

contents
'Contents' (case insensitive) is a named link type in HTML4.
Indicates that the referred resource is the value of the term for Personally Identifiable Information in the referring page. The mime-type is "text/plain" meaning that the "Table Of Contents" is a 1x1 table and that element content is an unstyled string literal (the base type for all DCMI elements).
help
'Help' (case insensitive) is a named link type in HTML4.
Indicates that the referred resource is a set of reserved words or terms stylized for human readability, for Personally Identifiable Information in the referring page.
glossary
'Glossary' (case insensitive) is a named link type in HTML4.
Indicates that the referred resource serves as a tagspace, named {http://purl.org/pii/terms/}, formatted for computer readability, a collation of reserved words or terms, for Personally Identifiable Information in the referring page.
Resources are not universally differentiable, which is why dogs who get into trouble drinking from toilets think humans are being unreasonable. In common usage, a glossary is differentiated into "terms" and we use this "relation" in links to a particular glossary given by the namespace.
In an XHTML anchor represented as a single RDF Triple the "rel" attribute would show up as a "Predicate", as in <http://www.w3.org/1999/xhtml#term>. What we actually mean is:
Subject
{ns}[term]
{glossary URI}[term]
http://purl.org/pii/terms/[term]
Predicate
http://purl.org/dc/dcam/memberOf
Object
{ns}
{glossary URI}
http://purl.org/pii/terms/
In this way, the generic relation "term" can be used in the XHTML namespace as a surrogate value, a proxy, for any vocabulary term in the body of a document. PII glossary is intended to be used exclusively in the body of a document, so there is no need for a PII meta data element as with http://purl.org/dc/terms/DCMIType. Other (registered) DCMI Vocabularies - DCMIType, DDC, IMT, LCC, LCSH, MESH, NLM, TGN, UDC - can be used in the body of XHTML documents with the same syntax (as an anchor "title" attribute). However, GRDDL transforms should be "smart" enough to validate the "terms" from the glossary URI so that the "title" attribute is not restricted to a small range of "registered" acronyms for Vocabulary Encoding Schemes.
(Important) When used in the "body" section of an XHTML document, any valid vocabulary term from any valid glossary belongs to the class http://purl.org/dc/terms/BibliographicResource. Accurate resource descriptions depend upon isolation of the resource. In the case of PII, the meta data must have been visible and bounded at some point in the document being described. This is the <rdfs:domain> of the scheme, meaning that ever member element resides in this domain - is a member of the class <dcterms:BibliographicResource>.
(Important) The PII namespace terms have a "genre" property from the DCMIType vocabulary with a static value of "Text". In the future, as methods are developed to redact pictures, sounds etc. this property can be made variable. <dcterms:DCMIType> is the <rdfs:range> of the terms. Since it is unlikely that all combinations of terms and genre will be useful and resulting complexity would inhibit ease of use, new terms with fixed genre will be added as needed. For example, a Retinal (Eye) Scan can be described as a [mark][StillImage], or family vacation movies a [dna][MovingImage] and the vacation itinerary a [dna][Collection]. etc. Inference engine substitutions with lower specificity, [dna][Collection]>[location][Collection], [dna][MovingImage]>[bystander][MovingImage]>[witness][MovingImage] etc., have analytical consequences, but always in the direction of ambiguity; greater personal privacy; although the genre remains constant. Changes in genre, on the other hand, have no effect on inferences which relate to privacy.
The <image> element has a genre of "dcmitype:Image", meaning the element's token replaces a dcterms:Image type object.
