Hi Robbie

>Finally, with regards to the files in the folder Reuters Samples: I
cannot confirm the validity of these files as I cannot find the XML
Schema's used by Reuters. In particular, the XML namespace "rtr"
points to "http://www.reuters.com/ns/2003/08/content", however there
is no associated schema location.

1. The Reuters documents are very early samples based on an old XSD; the XSD has subsequently evolved. The IPTC Autumn meetings will shortly be held in Prague (w/c 15 Oct); a number of XSD updates will be approved. The Reuters samples will be brought up to date after the IPTC meetings.

2. http://www.reuters.com/ns/2003/08/content: You are correct; the schema location has yet to be enabled by Reuters. I will advise this list when it has been done. For now, it should be possible to suppress validation of the rtr namespace markup via your chosen XML validator.

Subject: [newsml-g2] Validation of the provided NewsML-G2 examples

Dear members of the NewsML-G2 interest group,

In order to understand NewsML-G2 more thoroughly I've been studying
the examples available on the yahoo group discussion forum (in the
section files, contributed-examples). However, I did found some minor
problems with these files as some cannot be validated against the
latest draft version of NewsML-G2 (DRAFT-NewsML-G2_1.0-
spec-NewsItem-Power_3.xsd).

In particular I've found some problems with the following files:
1. The file "EBU template NewsML-2 r3.xml" (section interoperability
tests):
- Lines 37, 67, 89:
contains invalid attributes "validfrom", "validto", and "idrefts"
in the element "rightsInfo".
- Lines 50, 73, 95:
contains invalid element "affiliation" as part of the
element "personDetails".
- Line 237:
contains invalid attribute "chnllang" in the element "channel".

2. The file "Example-SmallArticle-NITFcontent.xml" (section tutorial):
- Line 43:
contains invalid attribute "words" in the element inlineXML.
I guess this should be "wordcount" instead.

All other files in the folders tutorial and interoperability tests
appear to be XML valid.

Can someone confirm these are (known?) issues. With regards to the
first file (EBU template), does someone have a suggestion how to
correct the XML file so it can be validated to NewsML-G2 draft
version 3 schema?

Finally, with regards to the files in the folder Reuters Samples: I
cannot confirm the validity of these files as I cannot find the XML
Schema's used by Reuters. In particular, the XML namespace "rtr"
points to "http://www.reuters.com/ns/2003/08/content", however there
is no associated schema location.

Can someone provide the XML Schema for this namespace or point me to
the location thereof?

Thanks in advance for any feedback.

Robbie,

I had to do some cross-checking before giving you a sound answer
(all this goes back to early July for me with a lot of water under
the bridge since then).

Actually, most of the errors you spotted come from the fact that my
instance implements some changes agreed but not implemented yet.

I expect these changes to be in the next version of the
specification after the meeting in Prague next week.  After this, it
should validate although I might have to do some adjustment to stick
to the actual implementation in the spec.

Dear Misha,

> How do I search for "newsItem"?

Using the Swoogle search engine: http://swoogle.umbc.edu/
For example, Swoogle found 45 ontologies with "newsItem"
http://swoogle.umbc.edu/index.php?option=com_frontpage&service=search&queryType=\
search_swd_ontology&searchStart=1&searchString=newsItem

or: 391 documents:
http://swoogle.umbc.edu/index.php?option=com_frontpage&service=search&queryType=\
search_swd_all&searchStart=1&searchString=newsItem

The results are not really clustered in a smart way, and you will find
many duplicates. This is the main criticism I would make to Swoogle:
their clustering and ranking algorithm. On the other side, nobody knows
yet how to really do that with RDF documents in the Semantic Web community.

Among the interesting results to this query, you will find for example
the NewsML 1.2 ontology made my Rhizomik:
http://rhizomik.net/ontologies/2006/01/NewsML_1.2Onto.owl

Hope that helps!

Subject: Cool URIs for the Semantic Web

wolf_misha

W3C First Public Draft: Cool URIs for the Semantic Web
Leo Sauermann and Richard Cyganiak (eds), W3C Technical Report

W3C announced that the Semantic Web Education and Outreach Interest Group
has released a first Working Draft for "Cool URIs for the Semantic Web."
Comments on this draft are requested by 21-January-2008. The document
explains the effective use of URIs to enable the growth of the Semantic
Web. URIs (Uniform Resource Identifiers) more simply called "Web
addresses" are at the heart of the Web and also of the Semantic Web.
It gives pointers to several Web sites that use these solutions, and
briefly discusses why several other proposals have problems. Web
documents have always been addressed with URIs (in common parlance often
referred as Uniform Resource Locators, URLs). This is useful because it
means we can easily make RDF statements about Web pages, but also
dangerous because we can easily mix up Web pages and the things, or
resources, described on the page. So the question is, what URIs should
we use in RDF? To identify the frontpage of the Web site of Example Inc.,
we may use 'http://www.example.com/'. But what URI identifies the company
as an organisation, not a Web site? Do we have to serve any content
(HTML pages, RDF files) at those URIs? In this document we will answer
these questions according to relevant specifications. We explain how to
use URIs for things that are not Web pages, such as people, products,
places, ideas and concepts such as ontology classes. We give detailed
examples how the Semantic Web can (and should) be realised as a part of
the Web. The draft document is a practical guide for implementers of the
RDF specification. It explains two approaches for RDF data hosted on
HTTP servers (called 303 URIs and hash URIs). Intended audiences are
Web and ontology developers who have to decide how to model their RDF
URIs for use with HTTP. Applications using non-HTTP URIs are not covered.
This document is an informative guide covering selected aspects of
previously published, detailed technical specifications.

I see that the NewsML-G2 language/@tag is of type "xs:language". Does xs:language support BCP 47? I think not. The XML Schema Datatypes spec seems to still refer to RFC 3066.

It doesn't really matter.  Syntactically, all that has happened in the
transition from RFC 3066 to RFC 4646 is that the syntax of well-formed
language tags has narrowed and the range of valid language tags has
grown.  XML Schema only specifies syntax, so the latter effect is of no
consequence: what is more, no valid language tag has changed its meaning.

Well-formed but not valid language tags, however, are not like well-formed
but not valid XML.  They are much more like unassigned Unicode characters;
that is, they should never be used by anyone for any purpose, because
at any time they may be assigned an official meaning.  Therefore, it
doesn't matter that "abcd-efgh" is no longer a well-formed language tag,
because it is not and never was a valid tag for any language.

> Note that our Schema annotation says "Values must conform to BCP47".

You might want to change that to "Values must be valid BCP 47 language
tags" or the like.

Dear NewsML-G2 interest group,

Good news: the IPTC standards committee has approved last Tuesday (29 jan) the specification of NewsML-G2 2.0 (it was finally agreed to start the generation 2 standard with a version 2.0 in order to avoid ambiguities with NewsML v1.2).

The specification document should be released by the end of this month, with the associated set of schemas and controlled vocabularies (newscodes), plus some examples. All information will be clearly accessible on the IPTC Web site.

It was a huge work for us, and we hope that you will make a great use of this brand new news industry standard.

The next step for us is to apply NewsML-G2 to real-life news production (text, photo, graphics, video and multimedia content). Already, news agencies (e.g. Reuters, Hina, ANSA, AFP) and broadcasters (e.g. VRT) are working on it.

This group is the best collaborative channel for the many providers who will implement NewsML-G2 in the short term, so please post your comments and questions here. This will be the source of information for an upcoming guidelines document (“How To implement NewsML-G2” or “NewsML-G2 for dummies”) that we intend to produce during the next months.

All the best

In case this is relevant ...

NewsML-G2 [1] defines a string-derived datatype called QCode.  A
QCode (Qualified Code) looks like this:

    CodingSchemeAlias:Code

The CodingSchemeAlias maps to an IRI representing the CodingScheme.
The IRI obtained by appending the Code to this IRI represents the
Code.  The Code can contain (and start with) most characters.  The
main exception is white space.  The Code can be entirely numeric.

QCodes are used as attribute values.  Such attributes accept QCodes
only, so there is no conflict with IRIs/URIs.

W3C has published a report on a workshop of interest for the NewsML users community :

W3C Video on the Web Workshop Report

See also the Workshop position papers: http://www.w3.org/2007/08/video/papers

1. Metadata : NewsML-G2 seems up to the point, re the topics of discussion. But only MPEG 7, SMIL, iTunes XML, Yahoo! MediaRSS, CableLabs VOD Metadata Content were considered. W3C is thinking about creating a WG for this : the IPTC should definitely be part of it.

2. Adressing into video content: NewsML-G2 has some basic capabilities in this field (partMeta properties). We would be interested a comparison btw our std and SMIL, MPEG-7, MEPG-21 or temporal URI solutions (cited in the paper). W3C is thinking about creating a WG for this : we have to stay in the loop.

3. Rights expression language: again a topic of interest for us. And a field of evolution for NewsML-G2, waiting for some work from NewsML-G2 developers (i.e. you).

Subject: IPTC releases first formal specs for NewsML-G2

mdiptc

This is today's IPTC media release on the release of the G2-Standards - including NewsML- G2 - to the public:

Exchanging News Made Easy with IPTC G2-Standards

LONDON (England), 26 February 2008 -- A new era in the sharing and publishing of news starts today with the launch of NewsML-G2 and EventsML-G2, the first parts of a new framework of XML-based news exchange formats from the International Press Telecommunications Council.

To support some of the latest innovations in web technology, NewsML-G2 allows the bundling of multiple news items -- articles, photos, videos or whatever -- and a detailed description of their content and how the items relate to each other. Whether populating a web site with complex news packages or building bundles of news items for resale or archiving, NewsML-G2 provides an easy way to package and exchange news.

EventsML-G2 provides a detailed way to describe any event (a football game, a convention, a community event) so that sharing and databasing can be done quickly, easily and with a minimum of errors. Many aspects of an event such as the starting time, duration, description of the event and contact information, can be encoded in a way that is easily understood and publishable even across multiple languages.

“This is a breakthrough in news exchange format design as G2-Standards cover a wide range of news content to cope with the growing demand for individualised news products” said IPTC Chairman Stéphane Guérillot, and “this all is achieved by a common framework which makes the adoption and implementation of G2-Standards easy and requires much less resources”.

This initial release of IPTC's G2 family of standards coincides with the 10th anniversary of XML, the lingua franca of the World Wide Web. Released in February 1998, XML brought the structure of web documents into sharper focus by allowing content providers (such as news agencies, newspapers, news websites, radio and TV stations) to create and publish complex documents using relatively simple and widely supported development tools. In fact, many XML tools are available free on the Internet.

G2-Standards also fit into the Semantic Web initiatives of the World Wide Web Consortium, enriching content so that computers can more easily search the huge universe of news. The goal is to better help news agencies manage and distribute their massive libraries of current and archived news content, and to help customer search engines find content quickly and accurately.

G2-Standards can be easily combined with IPTC's groundbreaking NewsCodes, which provide a rich suite of standard terms for describing news, to give news agencies amazing flexibility in how news can be bundled for downstream users. With widely available digital news archives now dating back to 1850 or earlier, news agencies, librarians and archivists have a special interest in the rapid searching and retrieval of news, which NewsCodes can accelerate to help drive revenue growth.

The new G2-Standards are available for download at no cost

from http://www.iptc.org/G2-Standards

As always, IPTC G2-Standards and NewsCodes can be incorporated into products without any payment of royalties or usage fees, subject to acknowledging IPTC's license agreement.

About IPTC: The IPTC, based in London, UK, is a consortium of the world's major news agencies, news publishers and news industry vendors. It develops and maintains technical standards for improved news exchange that are used by virtually every major news organization in the world.

Information on all IPTC standards such as the new family of IPTC G2-Standards, the existing NewsML 1, NITF, SportsML, IIM standards and the NewsCodes together with a list of existing members and information on how to join is available at http://www.iptc.org

So, the NewsML-G2 specification and XML schemas are available at:

If you want to use only the newsItem object, you only have to download the “NewsML-G2 specification documents zip-package”, with or without the XML schema documentation. You will find both Core and Power conformance PDF documents plus the associated XML schemas.

The XML schema documentation is a big HTML page with a large set of associated images, exported from XML Spy: it allows for an interactive browsing of the XML structures if you have no XML schema editor like XMLSpy, Oxygen or Stylus Studio.

If you want to use also the packageItem, conceptItem and knowledgeItem objects, you have to download also the “IPTC News Architecture for G2 specification documents zip-package” , with or without the XML schema documentation. You will find a copy of the framework schemas inside, already present in the NewsML-G2 package. You can put all schema files (NewsML-G2 specific and NAR) in the same directory.

Tell us if you would prefer a different packaging, e.g. a Core Conformance Level package and a Power Conformance Level package, with all objects present in it.

Please tell us about your implementations. Currently we know about implementations from the development team (AFP, EBU, HINA, Reuters in alphabetical order) but we would like to know more about other implementations. Some of us will post to this list samples of NewsML-G2 instances, so you can make your mind about its use.

Also, the discussion about evolution (NewsML-G2 2.1) has begun. We will communicate about what we intend to add, and we would like to hear about your requests.

Steve's mail (sent to the NITF list) is very confused.

>  [...] NewsML (primarily championed by Reuters)

Reuters contributed a very early version of NewsML, many years ago.
The IPTC developed it's own NewsML 1.0, about 7 years ago.  This
standard has had two further minor releases since then, hence is
now NewsML 1.2.

A few years ago, the IPTC decided to develop a new generation of
standards (called "G2").  After many person-years of work, the
first two of these standards (NewsML-G2 and EventsML-G2) were
announced on 26 February 2008 in this IPTC Press Release:
http://www.iptc.org/pages/prel_20080226.php

>  approaches to extending the capabilities of NITF to encompass
>  multiple media types and sets of information.  [...]  Reuters

None of the versions of NewsML was designed as an extension of
NITF.  NewsML has always been content agnostic and is used to
deliver text, XHTML, NITF, photos, graphics, video, and complex
packages.  Atom predates NewsML-G2 significantly.

Subject: [nitf] Summer of Code proposal

FYI for the NITF group:

Each year Google sponsors a "Summer of Code" program in which students
are paid to create open-source software. See
http://code.google.com/opensource/gsoc/2008/faqs.html

The Drupal CMS development community has an organized approach to SoC in

which ideas are refined and support aligns behind various proposals.

Today I proposed the following: http://groups.drupal.org/node/9758

Text follows:

NITF/Atom/NewsML extensions for FeedAPI

I'm crossposting this to the following groups, all of which have a dog
in this hunt: SOC2008, Knight Foundation, Newspapers on Drupal, RSS &
Aggregation.

News agencies, "legacy" newsroom management system implementors,
publishers and archiving companies all support an XML standard called
News Industry Text Format (NITF), developed by the International Press
Telecommunications Council.

We need a robust, broadly supported common NITF feed handler that works
with the Drupal FeedAPI framework, ultimately enabling loading of NITF
data into CCK nodes with configurable entity mapping. This feed handler
should expose its own API so that additional handlers can be added to
process NewsML (primarily championed by Reuters) and Atom wrappers (used

by the Associated Press in AP Exchange).

This is a foundational piece that's needed for Drupal to be a longterm
solution to many news-handling requirements of news publishers, who
increasingly are flocking to Drupal as a website solution.

I'm proposing this as a Google Summer of Code idea and offering to serve

as a mentor to the project.

This project is straightforward in theory but not in practice, as the
quality of NITF implementation varies more than a little bit among the
various data providers. In addition, both AP and Reuters have come up
with significantly differing approaches to extending the capabilities of

NITF to encompass multiple media types and sets of information. The AP
is moving to a search-based "wire" in which editors will be able to
create ad hoc and stored queries, exporting either individual NITF items

or Atom feeds containing additional metadata and embedded NITF. Reuters
originated and obtained IPTC approval of a "wrapper" called NewsML that
predates Atom significantly.

IPTC also maintains standards for events, sports data, TV listings, et
cetera. Any work on this project should provide a sound foundation for
further projects in those areas.

Town News, a US-based Web service provider to a number of smaller
newspapers, contributed an NITF PEAR class that may be of use.

All I'm trying to do in mentioning Reuters is to give Reuters credit for
initiating and pushing NewsML.  And Reuters undeniably was the force
behind NewsML. When NewsML 1.0 was announced, I was interviewed by a PR
agent writing a press release ... for Reuters.

As for the relationship between NITF and NewsML, perhaps I should have
said "solving the packaging problems that remained after NITF" instead
of "extending the capabilities of NITF." We all knew, the day NITF
rolled out the door, that packaging multiple items of multiple types was
an unsolved problem. NewsML may or may not be a great solution -- I
don't really know because NewsML is irrelevant to those of us in the
United States who rely on the Associated Press for data. AP doesn't use
NewsML, and doesn't even make good use of NITF.

My immediate concern is not standards creation, but rather the creation
of low-cost, automated, highly targeted information products at our
newspapers, derived from wire service data.  That's why I'm proposing
the SoC project to the Drupal development community.

Drupal is an open-source Web content management framework. It's used by
tens of thousands of websites ranging from personal weblogs to major
newspaper sites (and the Onion). A robust and extensible set of NITF and
NewsML parsers for Drupal would be a valuable tool.

So if anyone involved in the standards process, or in the creation of
data feeds using those standards, would like to volunteer time, serve as
a mentor, or provide code for this project I'd be delighted.

While this is proposed as a Google SoC project, it may also qualify for
funding under a Knight challenge grant program, or direct funding of one
of the many media companies that would benefit from it, so I'm confident
it's going to happen one way or the other.

Subject: Cool URIs for the Semantic Web

wolf_misha

[From XML Daily Newslink. Friday, 21 March 2008]

W3C Last Call Working Draft: Cool URIs for the Semantic Web
Leo Sauermann and Richard Cyganiak (eds), W3C Technical Report

W3C announced that members of the Semantic Web Education and Outreach
(SWEO) Interest Group have published the Last Call Working Draft for
"Cool URIs for the Semantic Web." The document is intended to become
a W3C Interest Group Note giving a tutorial explaining decisions of
the TAG for newcomers to Semantic Web technologies. It was initially
based on the DFKI Technical Memo TM-07-01 and was subsequently published
as a W3C Working Draft in December 2007; it was reviewed by the Technical
Architecture Group (TAG) and the Semantic Web Deployment Group (SWD).
The document is a practical guide for implementers of the RDF
specification. The title is inspired by Tim Berners-Lee's article "Cool
URIs don't change". It explains two approaches for RDF data hosted on
HTTP servers. Intended audiences are Web and ontology developers who
have to decide how to model their RDF URIs for use with HTTP. Applications
using non-HTTP URIs are not covered. The document is an informative guide
covering selected aspects of previously published, detailed technical
specifications. The Resource Description Framework (RDF) allows users
to describe both Web documents and concepts from the real world -- people,
organisations, topics, things -- in a computer-processable way. Publishing
such descriptions on the Web creates the Semantic Web. URIs (Uniform
Resource Identifiers) are very important, providing both the core of
the framework itself and the link between RDF and the Web. This document
presents guidelines for their effective use. It discusses two strategies,
called 303 URIs and hash URIs. It gives pointers to several Web sites
that use these solutions, and briefly discusses why several other
proposals have problems. It is important to understand that using URIs,
it is possible to identify both a thing (which exists outside of the web)
and a web document describing the thing. For example the person Alice
is described on her homepage. Bob may not like the look of the homepage,
but fancy the person Alice. So two URIs are needed, one for Alice, one
for the homepage or a RDF document describing Alice. The question is
where to draw the line between the case where either is possible and the
case where only descriptions are available. According to W3C guidelines
in "Architecture of the World Wide Web, Volume One," we have an Web
document (there called information resource) if all its essential
characteristics can be conveyed in a message. Examples are a Web page,
an image or a product catalog. The URI identifies both the entity and
indirectly the message that conveys the characteristics. In HTTP, a
status 200 response code should be sent when a Web document has been
accessed, a different setup is needed when publishing URIs that are
meant to identify entities.

I have some questions about Sematic Web issues. NewsML-G2 has been designed with
SemWeb compatibility in mind. Is there a guide somewhere that explains how it is
compatible with relation to all the SemWeb formats, tools and acronyms? I'm
thinking of GRDDL, OWL, SKOS, RDF, et al.

If anyone's gone ahead with work in this area I would also be interested in
hearing about it. Even if it's just vague plans I'd like to know what the level

AFP is currently doing such a development.

They are 2 aspects in your question:
1) the standardization of a formal ontology using OWL, the RDF/XML
representation of NewsML-G2 documents
2) the transformation software (NewsML-G2 -> RDF/XML)

Re 1) this is something we will work on as part of a R&D project. I would expect
that the IPTC "standardizes" this ontology model, via the NAR WP.
Re 2) I have already been working on it. That's cool for importing NewsML-G2

Subject: IPTC G2 Standards and the Semantic Web

wolf_misha

Hi Paul,

First of all, the Semantic Web is (of course) based on triples, eg:

    *Oil* is a *Subject* of *Story 1234567*

In most cases, the items in the triples need to be URIs.

The G2-Family of IPTC Standards supports this by assigning URIs to
each metadata container (eg Subject) and by requiring that each
News Item has a guid which takes the form of a URI.

The G2-Family of Standards also encourages the use of QCodes
to represent values (such as *Oil*).  Each QCode represents
a URI.

Thus we have the three URIs for (eg):

    *Oil* is a *Subject* of *Story 1234567*

To convert these to RDF, we use GRDDL.  This mechanism requires
that an XSLT stylesheet be associated with the News Item, either
via an attribute on the root element or via an association with
the namespace of the G2 Standard.

The above will allow the extraction of straight-forward triples.

Reuters provided a GRDDL transform about 2 years ago.  This is now
out-of-date and someone needs to write a new one or update the old
one.

There are more difficult triples to be harvested, representing
statements about statements, eg:
-  who asserted it
-  when did they assert it
-  with what confidence did they assert it

The right way to construct triples representing these is under
discussion in the Semantic Web community.

I have some questions about Sematic Web issues. NewsML-G2 has been
designed with SemWeb compatibility in mind. Is there a guide somewhere
that explains how it is compatible with relation to all the SemWeb
formats, tools and acronyms? I'm thinking of GRDDL, OWL, SKOS, RDF, et
al.

If anyone's gone ahead with work in this area I would also be interested
in hearing about it. Even if it's just vague plans I'd like to know what
the level of interest is on this list with regard to SemWeb, public
exposure of "interoperable" data and the implications for the news biz.

Subject: Relationship direction

wolf_misha

misha.wolf@...

Hitherto, all relationships in the G2 family of IPTC standards have been between two nodes and their direction has been non-problematic:

In the case of broader and narrower the direction is clear.

The relationship is true in both directions for:

- sameAs

- related at the Core Conformance Level (as it means SeeAlso)

In the case of related at the Power Conformance Level there hasn't been a problem hitherto, as we can name the relationship (using @rel) in such a way that it is true that the lexically enclosing node has relationship X to the enclosed node (ie to the one indicated by the @qcode on related). For example, if rel="rel:hasCurrency", then one would expect the @qcode on related to represent a Currency and the qcode on the enclosing element to represent a Geopolitical Unit:

  <concept>
   <conceptId qcode="G:1A"/>
   <name role="nameRole:main" xml:lang="en">Northern Mariana Islands</name>
   <definition role="defRole:main" xml:lang="en">Commonwealth of the Northern Mariana Islands</definition>
   <sameAs qcode="ISO-3166-1-Alpha-2:MP"/>
   <sameAs qcode="ISO-3166-1-Alpha-3:MNP"/>
   <sameAs qcode="ISO-3166-1-Numeric-3:580"/>
   <related rel="cptRel:dependencyOf" qcode="G:6J"/>
   <related rel="cptRel:hasCurrency" qcode="C:6"/>
   <broader qcode="M:A9"/>
  </concept>

At today's IPTC News Architecture WP meeting we agreed to allow a bag as a child element of related, in the same way that we allow a bag as a child element of subject. Together with the existing @validFrom and @validTo attributes, this will allow us to express, for example, that on date D1, Yogoslavia split into entities X, Y and Z. I'm concerned about the reverse case, eg that on date D2, Tanganyika and Zanzibar merged to form Tanzania. Now one could rely completely on @rel for this, eg rel="rel:Merged" and rel="rel:Demerged", and write the GRDDL transform so that it knows that Merged runs one way and Demerged runs the other way. Or should we add a @dir attribute to related, for this sort of case?

Subject: MIME Type Question

algermissen1971

Hi,

reading through the NewsMLg2 spec ( the document "Core Conformance
LevelNewsML-G2 Specification 2.0" ) I noticed the mime type definition
in section 10.2.2.

Can someone clarify their status regarding IANA registration? I did
not find them on www.iana.org.


Would the following HTTP POST request be a valid use of the type
application/vnd.iptc.g2.newsitem+xml

POST /myResource HTTP/1.1
Host: www.example.org
Content-Type: application/vnd.iptc.g2.newsitem+xml

<?xml version="1.0"?>
<newsml:newsItem xmlns:newsml="http://iptc.org/std/nar/2006-10-01/"
standard="NewsML-G2" standardversion="2.0">
                  <!-- item content here -->
</newsml:newsItem>

Thanks in advance,

Jan

Subject: Entity URI lookup service & URI Disambiguation

wolf_misha

fyi

OKKAM

OKKAM (European Community funded project) aims at developing an Entity Name System (ENS) for the [Semantic] Web which can make sure that the same entity (individuals, location, organization, event, product, …) is referred to through the same URI.

The ENS repository stores existing URIs + enough attributes of the corresponding real world entity to help identify it

􀁺 A OKKAM URI for the entity
􀁺 An entity profile - attributes to help identify entity
􀁺 A collection of metadata
􀁺 A list of alternative URIs (including the preferred URI, if any)

ENS is about reusing existing URIs in content creation

Lots of methods and tools used for URI disambiguation can be shared and reused

The ENS is based on the idea that, in general, having multiple URIs for the same thing is a bug, not a feature

Using billions of distributed owl:sameAs statements to link multiple URIs that refer to the same entity is impractical.

They called it ENS because they see it doing a similar job (linking entities to URIs) to DNS (linking URLs to IPs addresses), though I think it's a confusing parallel to draw. There must be questions about the viability of such a service since the service returns a ranked list of possible matches & does not attempt to avoid duplication alltogether & seems to recognise that entities will have different meanings in different contexts.
