  9. 9. NITF 4.0: Core, Power, G2 G2 Power Core Metadata not in NITF G2 expansion of NITF possible Map to G2 No map to G2
  10. 10. Core Conceptual Model <ul><li>Containers : </li></ul><ul><li>paragraph </li></ul><ul><li>sub-headline </li></ul><ul><li>table </li></ul><ul><li>media </li></ul><ul><li>list </li></ul><ul><li>sidebar </li></ul><ul><li>preformatted block </li></ul><ul><li>editorial note </li></ul><ul><li>Closers : </li></ul><ul><li>credit-line </li></ul><ul><li>biographical blurb </li></ul><ul><li>Many Containers hold Enriched Text : </li></ul><ul><ul><li>phrases (people, titles, etc) </li></ul></ul><ul><ul><li>highlights (stylistic emphasis) </li></ul></ul><ul><ul><li>link </li></ul></ul><ul><ul><li>break </li></ul></ul>article abstract headline super-headline sub-headline main-headline byline Containers Closer G2 main-headline byline phrases link
  11. 11. NITF Power Model nitf head title body Most NITF <head> elements and attributes map to G2 (or make no sense) Notable exceptions are <iim> <pubdata> and <revision-history> Map details at http: //tinyurl .com/2rgfx6 meta tobject iim docdata pubdata revision-history iim pubdata revision-history
  12. 12. NITF G2: Embedded Media <ul><li>NITF articles often embed a media item, e.g. image, audio, video, etc </li></ul><ul><li>The media item often has associated metadata, e.g. copyright, mime-type, height, width, etc. </li></ul><ul><li>When switching to NITF+G2, what do you do with the media item and its metadata? </li></ul>media body.content nitf media-metadata media-reference media-caption
  13. 13. NITF G2: Embedded Media <ul><li>It depends. </li></ul>
  14. 14. NITF G2: Embedded Media <ul><li>Three options: </li></ul><ul><ul><li>Create an item for the media object and use packageItem to glue the NITF article and media object together </li></ul></ul><ul><ul><li>Use links in the item header to reference media objects needed for the item to display correctly </li></ul></ul><ul><ul><li>Embed the media object in the NITF article </li></ul></ul>
  15. 15. NITF G2: Embedded Media <ul><ul><li>Create an item for the media object and use packageItem to glue the NITF article and media object together </li></ul></ul>newsMessage itemSet packageItem newsItem newsItem nitf media
  16. 16. NITF G2: Embedded Media <ul><ul><li>Use a link in the item header to reference the media object </li></ul></ul><ul><ul><li>(e.g. a graphic / audio / video on the web). </li></ul></ul>newsMessage newsItem nitf media link
  17. 17. NITF G2: Embedded Media <ul><ul><li>Embed the media object in the NITF article </li></ul></ul><ul><ul><li>Provide context </li></ul></ul><ul><ul><li>Exact placement </li></ul></ul><ul><ul><li>Specific order </li></ul></ul><ul><ul><li>Captions often specific to the article </li></ul></ul>media body.content nitf media-reference newsItem media-caption link
  18. 18. NITF G2 <ul><li>The choices with embedded media illustrate a general conclusion </li></ul><ul><li>When using NITF within NewsML-G2 there will be a number of choices that news publishers need to make </li></ul><ul><li>How much to embrace the “G2 Way”? </li></ul>
  19. 19. NITF G2: qcodes <ul><li>The NAR makes extensive use of qcodes </li></ul><ul><li>Should NITF adopt qcodes too? </li></ul><ul><li>qcodes are “qualified codes” </li></ul><ul><li>Scheme identifier followed by a colon followed by a code (which can contain a colon), e.g. </li></ul><ul><li>qcode=“org:DJ” </li></ul><ul><li>qcode=“poi:cz:praha” </li></ul>
  20. 20. NITF G2: qcodes <ul><li>In NAR’s PCL text markup: </li></ul><ul><li><headline>The </li></ul><ul><li><inline qcode=“org:DJ”> </li></ul><ul><li>Dow Jones </inline> representative visited <inline qcode=“poi:cz:praha”> </li></ul><ul><li>Prague </li></ul><ul><li></inline> </li></ul><ul><li></headline> </li></ul>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>
  21. 21. NITF G2: qcodes <ul><li>NAR provides powerful metadata capabilities using qcodes </li></ul><ul><ul><li>Hooks into conceptItem (path to ontology) </li></ul></ul><ul><ul><li>Ambiguous assertions of identity </li></ul></ul><ul><li>Nothing to stop providers using qcode-like values for existing NITF attributes </li></ul><ul><ul><li><org value=“org:DJ”> </li></ul></ul><ul><li>Or could add non backward compatible qcode attribute to relevant elements </li></ul><ul><ul><li><city qcode=“poi:cz:praha”> </li></ul></ul>
  22. 22. NITF G2: qcodes <ul><li>Proposal : Do not add qcodes to NITF. </li></ul><ul><li>Instead, use NAR’s inlineRef and NITF’s id. </li></ul><ul><li>NAR’s <inlineRef> mechanism allows qcodes to be applied to any element that sports an XML id attribute </li></ul><ul><li>All NITF elements support id </li></ul><ul><li>Including the useful “catchall” <classifier> </li></ul>
  23. 23. NITF G2: qcodes example <ul><li><newsItem> </li></ul><ul><li><inlineRef idrefs=“e1” qcode=“e:happy” confidence=“77”> </li></ul><ul><li><name>Happiness</><description>Mirth.</> </li></ul><ul><li><inlineRef idrefs=“p7” qcode=“p:buddha”> </li></ul><ul><li><name>Gautama Buddha</></inlineRef> </li></ul><ul><li>… </li></ul><ul><li><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… </li></ul><ul><li></nitf></newsItem> </li></ul>
  24. 24. NITF 4.0: Next Steps <ul><li>Re-solicit comments on Yahoo groups </li></ul><ul><li>Resolve and harmonize discussion points </li></ul><ul><li>Draft an NITF-in-G2 User Guide </li></ul><ul><li>Vote on NITF 4.0 Proposal in Beijing </li></ul>
  25. 25. NITF Future <ul><li>Stability </li></ul><ul><ul><li>Few changes recently </li></ul></ul><ul><ul><li>Not even to integrate with NewsML-G2 </li></ul></ul><ul><li>Requests </li></ul><ul><ul><li>Inline markup </li></ul></ul><ul><ul><li>More complex and richer </li></ul></ul><ul><ul><li>Inspired by microformats, XHTML </li></ul></ul>
  26. 26. NITF Future: Drive Adoption <ul><li>Text article model is close to universal </li></ul><ul><li>And yet it is being re-invented: </li></ul><ul><ul><li>PRISM, microformats, RDFa, XHTML, etc. </li></ul></ul><ul><li>This hurts interoperability and therefore competition and costs </li></ul>article abstract headline super-headline sub-headline main-headline byline Containers Closer
  27. 27. NITF Future: Drive Adoption <ul><li>What is the best way to drive adoption? </li></ul><ul><li>We could promote the NITF format </li></ul><ul><ul><li>Evangelize the NITF tags amongst publishers of other kinds </li></ul></ul><ul><ul><li>Adopt more and more of the complex markup of XHTML </li></ul></ul><ul><li>We could promote the common article model </li></ul><ul><ul><li>Map from the model to XHTML, RDFA, etc. </li></ul></ul><ul><ul><li>De-emphasize the NITF tags themselves </li></ul></ul>
  28. 28. NITF Future: Drive Adoption <ul><li>In my view, the best way to drive adoption is to do a combination of the two </li></ul><ul><li>We should create an explicit article model (similar to the NAR) </li></ul><ul><li>We would then create maps from the article model to various formats </li></ul><ul><li>The IPTC would declare support for NITF as “first among equals” </li></ul>
  29. 29. NITF <ul><li>Any other business? </li></ul><ul><li>Date and place of next meeting: </li></ul><ul><ul><li>Beijing, China Spring 2008 </li></ul></ul><ul><ul><li>Děkuji! </li></ul></ul>
