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 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?

NITF G2: Embedded Media
It depends.
© IPTC – www.iptc.org 14
NITF G2: Embedded Media
• 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

NITF G2: Embedded Media
– Embed the media object in the NITF article
– Provide context– Exact placement– Specific order– Captions often
specific to the article

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”?
© IPTC – www.iptc.org 19
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”
© IPTC – www.iptc.org 20
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>
© IPTC – www.iptc.org 21
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”>
© IPTC – www.iptc.org 22
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>
© IPTC – www.iptc.org 23
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
© IPTC – www.iptc.org 26
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

NITF Future: Drive Adoption
• 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
© IPTC – www.iptc.org 28
NITF Future: Drive Adoption
• 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!
