altId in NewsML-G2

• Alternative identifiers may be useful to client systems• Hence the altId element, e.g.

<altId type=“gyiid:masterID”>105864332</altId>

• In NewsML-G2 2.15, altId is of type xs:normalizedString

<xsd:simpleType name="normalizedString" id="normalizedString">

<xsd:restriction base="xsd:string">

<xsd:whiteSpace value="replace"/>

</xsd:restriction> </xsd:simpleType>

• It turns out that type doesn’t do what we wanted


XML Schema normalizedStringxs:normalizedString is a whitespace-replaced string

– Replace whitespace characters with spaces (#x20)• #x9 (tab)• #xA (linefeed)• #xD (carriage return)

– Do not collapse whitespaces

For example the value of<altId type=“ex:eg">

Being an Identifier Is

a Full-Time Job

</altId>

Is interpreted as this" Being an Identifier Is a Full-Time Job "

But there are no validation errors!

CR00169Replace xs:normalizedString

• Create nar:g2normalizedString to replace NewsML-G2’s use of xs:normalizedString

• xs:string with the restriction pattern [\S ]*• \S matches anything but a whitespace• short for [^\f\n\r\t\v\u00A0\u2028\u2029]

• So [\S ]* means– zero or more (non-whitespace or space characters)

CR00170Change the data type of altId

In 2.15 altId is defined as xs:normalizedString

In 2.16 we are relaxing all restrictions on altIds

CR00170 alters the data type to be xs:string

http://dev.iptc.org/G2-CR00170-change-data-type-of-altId

Alternative identifiers used to be restricted to certain strings

An altId had to conform to xs:normalizedString

If not, it is altered by conforming implementations!

Now, any string may be used as an altId
