5. 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

6. XML Schema normalizedString
xs: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!

7. CR00169
Replace 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 [^fnrtvu00A0u2028u2029]
• So [S ]* means
– zero or more (non-whitespace or space characters)

8. CR00170
Change 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
