The IPTC's News Industry Text Format is an XML format for news article content and metadata. This presentation discusses the progress on the roadmap to NITF 4.0 - incorporating the Semantic Web, more complete namespace support and aligning NITF with IPTC's NewsML-G2.

      Chairman’s Report
      NITF = “News Industry Text Format”
      Defines the content and structure of articles
      IPTC’s most widely-used XML standard
      421 members on the Y! list
      down from 435 in October
      4 emails since October
      NITF 3.5 released in December 2009

    • NITF 4.0 Road Map
      In October 2010 we proposed a road map:
      Kick off NITF 4.0 in Spring 2010
      Discuss
      G2ization
      RDFization
      Namespaces
      Target NITF 4.0 for end of 2010

    • NITF 4.0 – Semantic Web
      Dear IPTC Standards Committee,
      Please set up a Working Group to consider
      RDF, Semantic Web and Linked Data.
      How might they relate to IPTC standards?
      Regards,
      NITF Working Group

    • NITF and the Semantic Web
      For a Dow Jones project, I created a representation of key article information
      I used semantic web vocabularies – chiefly FOAF and Dublin Core Terms
      But there was no match for “byline”
      I considered using G2’s <by> element
      But NITF’s <byline> was actually what I needed
      © IPTC – www.iptc.org
      9
    • Semantic Web:News Vocabulary
      IPTC could create a news-specific vocabulary of terms.
      I saw a need, as have New York Times and others
      © IPTC – www.iptc.org
      10
    • Semantic Web Vocabularies
      Best known RDF vocabularies are
      FOAF = Friend of a Friend
      http://xmlns.com/foaf/spec/
      DCMI Terms = Dublin Core Metadata Initiative Terms
      http://dublincore.org/documents/dcmi-terms/
      Other examples at http://vocab.org/

      11
    • Semantic Web Vocabulary
      An example from Dublin Core Terms:
      © IPTC – www.iptc.org
      12
    • Semantic Web Vocabularies
      An example from Dublin Core Terms:
      There are some news-specific terms that aren’t defined in other vocabularies, such as “byline”.
      We could define a news vocabulary (a relatively simple data model) or a full ontology (richer but more work).
      © IPTC – www.iptc.org
      13
    • NITF 4.0 and Semantic Web
      Should IPTC take a lead role?
      Other organizations are starting to create news vocabularies
      Are there meaningful differences between NITF and the G2 family?
      Maybe a way to bring the two closer together
      Note that NITF has always been “semantic”

    • Geographic Information
      Gerd Kamp from DPA Infocom discusses using NITF to represent locations:
      http://r.ka2.de/?p=595
      He found everything he needed
      Except for a way to represent a centroid
      Centroid is the central point of a place
      Expressed a latitude and longitude
      © IPTC – www.iptc.org
      15
    • A georss:point in NITF
      Adding a centroid using georss
      © IPTC – www.iptc.org
      16
    • Adding Latitude and Longitude
      We could add latitude and longitude to NITF’s location-related elements
      Maps as user interfaces to news are growing in popularity
      But geographic information can be quite complex
      Centroid, Bounding Box, Bounding Polygon…
      So can we consider a different approach?
      © IPTC – www.iptc.org
      17
    • The GeoRSS Namespace
      GeoRSS is widely used in RSS and ATOM
      Designed to be embedded in XML
      http://www.georss.org
      So why recreate those structures in NITF?
      © IPTC – www.iptc.org
      18
    • Foreign Namespace
      In NITF 3.5, we completed the support for “foreign namespaces” introduced into the schema in v3.4
      Specifically, the “enriched text” has a choice of
      <any namespace="##other"/>
      This allows other namespaces to be used within such NITF elements as caption, tagline, etc.
      © IPTC – www.iptc.org
      19
    • Foreign Namespaces Elsewhere?
      So far, we have only allowed non NITF namespaces within enriched text
      This means that NITF is a “closed” schema
      All innovation in the use of NITF needs to be centralized within the IPTC
      Do we want to allow other namespaces to be mixed in with NITF documents?
      Allow proprietary extensions to be “legal”
      © IPTC – www.iptc.org
      20
    • NITF 4.0 and G2
      IPTC’s G2 standard is a unified framework
      Packaging and exchanging news content
      Standard model for news metadata regardless of the content or media type
      However, NITF predates and stands outside the G2 framework
      Can NITF join the G2 family of standards?
      © IPTC – www.iptc.org
      21
    • NITF and G2
      We studied how SportsML became part of the G2 family
      It seems a similar path is possible for NITF
      The biggest change will be the inline adoption of QCodes in NITF
      Colon separated scheme:code syntax for controlled vocabularies
      © IPTC – www.iptc.org
      22
    • NITF and G2
      With work, NITF can be brought within the G2 framework
      NITF would bring inline semantics (entities) into G2
      Should NITF Classic live on?
      © IPTC – www.iptc.org
      23
    • NITF 4.0
      Unlocking the power of NITF
      Joining the Semantic Web
      Opening up to other namespaces
      Joining the G2 family of standards

      24
    • Other Text Markup
      NITF isn’t the only text markup effort
      Or even the most active
      HTML5
      hNews
      IPTC 7901
      © IPTC – www.iptc.org
      25
    • HTML5 New Elements
      HTML5 is introducing several new structural elements, including
      <section> <article>
      <aside> <header> <footer>
      HTML5 is moving confidently beyond presentation into news-like structure

      26
    • hNews
      A microformat for adding some news-specific semantics into display-ready HTML
      Adopted by Associated Press for recent Winter Games and forthcoming World Cup websites
      We know of around 200 other websites using hNews
      Starting to see some tools being built
      © IPTC – www.iptc.org
      27
    • IPTC 7901
      An idea to add markup to pre-XML text markup
      Can we use Markdown?
      The idea will be discussed later during the Standards Meeting
      © IPTC – www.iptc.org
      28
    • NITF Documentation
      Upgrading the NITF website. Some ideas:
      Simplify getting to the NITF specs
      Perhaps adopt Subversion for previous versions?
      Supply NITF <-> XHTML XSLT transforms
      Copy NITF DTD documentation into the XSD
      Modernize the documentation
      Discuss NITF and G2?
      Volunteers to take on any of the work?

      Any other business?
