Agenda

• Approval of minutes from previous meeting• Matters Arising• Chairman’s Report• State of NITF Today• NITF 4.0• Future of NITF• Other business• The next meeting


NITF Minutes

• Approval of Minutes from previous meeting: Tokyo 30th May 2007

NM0704.1


NITF Matters

• Matters arising?- I took over!- Děkuji to Alan Karben.


State of NITF Today

• News Industry Text Format

• “A solution for sharing news”

• Developed by News Publishers, for News Publishers

• Defines the content and structure of news articles

• NITF v3.4 in DTD and XML Schema

• http://www.nitf.org


State of NITF Today

• IPTC’s most widely-used XML standard– 455 members on the Y! list– Since June, 9 subscribed, 4 unsubs

• Recent history– NITF largely the same since 90’s– Consolidation: removed HTML formats,

streamlined enriched text, etc.– XML schema

• Stability


State of NITF Today

• Some activity– Only 27 Y! messages since June– No one responded to NITF profiles or

contributed to the G2 map

• Emerging Alternatives– XHTML, Microformats, RDFa, PRISM, etc.

• NITF is strong, but with looming challenges


NITF 4.0

• NITF Profiles: Core– Inline and structural markup

– No metadata that conflicts with G2– Slimmed-down set of NITF elements– http://tinyurl.com/ywzawr

• NITF Profiles: Power– Map Power metadata to G2 metadata– http://tinyurl.com/2rgfx6


NITF 4.0: Core, Power, G2

NITF G2: Embedded Media

• NITF articles often embed a media item, e.g. image, audio, video, etc

• The media item often has associated metadata, e.g. copyright, mime-type, height, width, etc.

• When switching to NITF+G2, what do you do with the media item and its metadata?

media

body.content

nitf

media-metadata

media-reference

media-caption



It depends.



• Three options:– Create an item for the media object and

use packageItem to glue the NITF article and media object together

– Use links in the item header to reference media objects needed for the item to display correctly

– Embed the media object in the NITF article

Use a link in the item header to reference the media object

(e.g. a graphic / audio / video on the web).

– Embed the media object in the NITF article

– Provide context– Exact placement– Specific order– Captions often

NITF G2

• The choices with embedded media illustrate a general conclusion

• When using NITF within NewsML-G2 there will be a number of choices that news publishers need to make

• How much to embrace the “G2 Way”?


NITF G2: qcodes

• The NAR makes extensive use of qcodes

• Should NITF adopt qcodes too?

• qcodes are “qualified codes”

• Scheme identifier followed by a colon followed by a code (which can contain a colon), e.g.

qcode=“org:DJ”

qcode=“poi:cz:praha”


NITF G2: qcodesIn NAR’s PCL text markup:

<headline>The

<inline qcode=“org:DJ”>

Dow Jones</inline> representative visited <inline qcode=“poi:cz:praha”>

Prague

</inline>

</headline>

In NITF

<hl>The

<org idsrc=“org” value=“DJ”>

Dow Jones</org> representative visited <city code-src=“poi” city-code=“cz:praha”>

Prague

</city>

</hl>


NITF G2: qcodes

• NAR provides powerful metadata capabilities using qcodes– Hooks into conceptItem (path to ontology)– Ambiguous assertions of identity

• Nothing to stop providers using qcode-like values for existing NITF attributes<org value=“org:DJ”>

• Or could add non backward compatible qcode attribute to relevant elements<city qcode=“poi:cz:praha”>


NITF G2: qcodes

• Proposal: Do not add qcodes to NITF.Instead, use NAR’s inlineRef and NITF’s id.

• NAR’s <inlineRef> mechanism allows qcodes to be applied to any element that sports an XML id attribute

• All NITF elements support id• Including the useful “catchall” <classifier>


NITF G2: qcodes example

<newsItem><inlineRef idrefs=“e1” qcode=“e:happy” confidence=“77”>

<name>Happiness</><description>Mirth.</><inlineRef idrefs=“p7” qcode=“p:buddha”><name>Gautama Buddha</></inlineRef>…<nitf><person id=“p7”>Buddha</> discussed the role of the mind in the pursuit of <classifier id=“e1”>happiness</> through the practice of the eightfold path…

</nitf></newsItem>


NITF 4.0: Next Steps

1. Re-solicit comments on Yahoo groups

2. Resolve and harmonize discussion points

3. Draft an NITF-in-G2 User Guide

4. Vote on NITF 4.0 Proposal in Beijing


NITF Future

• Stability– Few changes recently– Not even to integrate with NewsML-G2

• Requests– Inline markup– More complex and richer– Inspired by microformats, XHTML


NITF Future: Drive Adoption

• Text article model is close to universal

• And yet it is being re-invented:– PRISM, microformats,

RDFa, XHTML, etc.

• This hurts interoperability and therefore competition and costs

• What is the best way to drive adoption?• We could promote the NITF format

– Evangelize the NITF tags amongst publishers of other kinds

– Adopt more and more of the complex markup of XHTML

• We could promote the common article model– Map from the model to XHTML, RDFA, etc.– De-emphasize the NITF tags themselves



• In my view, the best way to drive adoption is to do a combination of the two

• We should create an explicit article model (similar to the NAR)

• We would then create maps from the article model to various formats

• The IPTC would declare support for NITF as “first among equals”


NITF

• Any other business?

• Date and place of next meeting:– Beijing, China Spring 2008

Děkuji!
