This directory contains
jp3_06.owl
(HyperDAML),
a representation of Chapter 1 of
Joint Publication 3-06: Doctrine for Joint Urban Operations
represented in the
OWL Web Ontology Language.
It is intended as a demonstration of how
Semantic Web
technologies can be applied to military doctrine and lessons learned.
Approach
We started with
Chapter.xml
and related XML documents provided by Jim Ritter
and generated
urban_ops-00-001.owl
and the other OWL documents discussed below by hand,
linking to various existing
DAML+OIL and OWL
datasets
and
ontologies
including:
Since XSLT
is being used to combine and display the XML document fragments,
we employed "structured RDF" to represent OWL information in a format that
could be processed by OWL while remaining validatable XML.
Example
urban_ops-00-001.xml
contains the original description of the introduction to
Joint Pub 3-06.
urban_ops-00-001.owl
(HyperDAML)
contains a corresponding version using OWL.
We'll use the
HyperDAML
tool to view the OWL content.
It marks up OWL content with hypertext links,
allowing a user to traverse the data web
the same way an agent or other program would.
Comparing
urban_ops-00-001.xml
to
urban_ops-00-001.owl
reveals several differences representative of the advantages offered by the Semantic Web:
- the security classification markings
Unclassified
and
U
have been replaced by references to a
standard URI
which contains the definition of
Unclassified
and its relationship to other classification markings.
This promotes consistency and supports automated reasoning over
markings without hardcoding logic into individual programs.
- another URI
is used to refer to metadata information on Joint Pub 3-06.
This eliminates duplication and promotes consistency.
This uses properties defined by
Dublin Core,
a widely used ontology for publications.
- Rather than duplicating information on Jim Ritter,
we link to
his entry
in an abbreviated OWL representation of the
CALL
organization chart.
Note that
CALL
links to
DCST-W,
which links to
DCST,
which links to
TRADOC,
etc.
Note also that the ranks for military personnel
are linked to a representation of ranks
that includes relationships between ranks among and between services.
The services are also represented using DAML.
Chapter.xml
uses
Chapter-001.xsl
to format the document using XSLT,
an important capability to preserve.
Chapter.owl (TBD)
similarly uses
Chapter-001-owl.xsl (TBD)
to format the OWL version of the document.
We'll use a different tool,
the
Object Viewer,
to explore the use of the Semantic Web to represent links among lessons learned,
tasks,
and
doctrine.
