NITF Matters

• Approval of minutes from the previous meeting– held on the 8 March 2010 (NM1002.1)

• Matters arising?


Chairman’s Report


• NITF = “News Industry Text Format”• Defines the content and structure of articles

Towards NITF 4.0


• Open up the schema– To give NITF users greater flexibility and control– Align NITF with other standards

• The NITF 4.0 road map:– XSD documentation <- Progress to report– Namespaces <- Progress to report– RDFization <- Now part of a broader IPTC initiative– G2ization <- Still to come

• NITF 4.0 started Spring 2010, target end of 2010– Still on track

XSD Documentation• Currently, only the NITF 3.5 DTD has documentation• An “experimental” NITF XSD with documentation

mechanically copied over:

• Comments requested, none received…

http://groups.yahoo.com/group/nitf/message/772

• We could update the NITF 3.5 XSD

NITF + Foreign Namespace e.g. Adding Geo Information


• Maps are popular ways to display news• It would be handy to be able to use GEORSS to add

latitude and longitude information into an NITF article

• Unfortunately, NITF doesn’t allow “foreign namespaces”

Foreign Namespaces

• A long-standing criticism of NITF is that it is closed to foreign namespacese.g. http://snee.com/xml/xml2005/industryschemas.html#d50e406

• NITF 3.5 added more complete support for foreign namespaces in enriched text – but not yet elsewhere

• We decided to turn NITF 4.0 into a more open schema• An experimental XSD can be found at

Experimenting with Namespaces

• I constructed an NITF instance document to help figure out where to add namespaces into NITF 4.0

• It is just an experiment, so I’m sure there are bugs and it is incomplete…


Testing is Important!

• The NITF 3.5 XSD foreign namespace support didn’t work as expected

• I wanted to be able to add some XHTML but couldn’t at first

• I had to change the processContents style to “lax”


NITF <head>

• Within the <head> it makes sense to add expansion slots within <docdata> and at the end of <head>

• Everywhere else is already generic (iim, pubdata) or too specific


NITF <body>

• Added namespaces to <body.head>…


NITF <body>

• … and within <media> …


NITF <body>

• … and within <block>.

• I experimented with namespaces outside of “containers” in the <body> but triggered XSD errors.

• Also, what would this “mean”?


After NITF <body>?

• I allowed foreign namespaces after the body

• But does this turn NITF into a “envelope” language?• Would it compete with NewsML-G2 or ATOM?

• And I didn’t experiment with anyAttribute– Just add anyAttribute to every NITF element?


NITF 4.0 and IPTC’s G2

• G2 is a unified framework for packaging and exchanging news content

• Standard model for news metadata regardless of the content or media type

• However, NITF predates the G2 framework

• With work, NITF can join the G2 family, just like SportsML• The biggest change will be the inline adoption of QCodes

– Colon separated scheme:code syntax for controlled vocabularies


Next Steps towards NITF 4.0

• Complete the foreign namespace work– Add anyAttribute– Publish a test document or two

• G2ization of NITF• Publish a test document or two

– Update the NITF documentation - a long-standing need• Could use the NITF chapter of the G2 guidelines• That chapter will need updating anyway


NITF

Any other business?

Date and place of next meeting:

Rome, Italy – November 2010
