Subject: Naming Conventions
Title: Naming Conventions
Hi Everyone,
What follows is an excerpt from a paper I'm building for a
subcommittee I chair which is directly related to our discussion on
naming conventions and the issues presented by John Silva's
presentation on ISO/IEC 11179. As you will gather, the paper
represents the convergence of issues across several standards and
standards groups, but I am only including the part that is relevant to
the discussion we had this week.
Note: this is an ongoing research project which is developing
much of a life of its own than I intended, but that happens. FWIW it
has led me down the path of exploring the DOM and more study of RDF
and Ontologies in general.
As you may know, there is no magic wand for unifying naming
conventions, and as difficult as it is, I have found that the
combination of namespacing for standards which have produced an xml
schema, using the namespace prefix, and a verbose naming convention
within the standards themselves, such as the one I suspect we will
produce, is the most workable if not the only workable method to use
to conform to what standards have emerged and are emerging.
Ciao,
Rex
The Human Physical
Characteristics Description Markup Language (HPCDML) and the
subcommittee of the OASIS HumanMarkup Technical Committee dedicated to
producing this xml-based language, is aimed at bringing together a
comprehensive synthesis of existing and planned standards for
documenting the Human Body. <snip>
When I say that I am beginning work, that is only partly true because
I have done quite extensive research work in the course of my
participation in the HumanML TC, the Web Services for Interactive
Applications and Remote Portals TCs and the newly minted Emergency
Management TC, and that work has led me to a conclusion that ties all
of these seemingly disparate efforts together and includes other
efforts, such as those of the Web 3D Consortium (X3D, H-Anim and
GeoVRML) as well. The conclusion is that there is actually little
original work that needs to be done, but there is a great deal of
study, comparison and compilation that does need to be done. I suspect
that a DAML-OIL-based application-specific RDF Schema/Ontology will
probably emerge from this work and the Human Physical Characteristics
Description ML will probably emerge from that work, as a Secondary
Schema of the Human Markup Language.
A sample of what I mean is
embodied in the prerelease Justice Department Data Dictionary recently
made available, ( (which will be) included in the list below),
which overlaps HumanML and Emergency Management. That document in pdf
form is 7.8M.
Similarly, among the five standards now mandatory for all federal
agencies for coding and sharing medical records, (according to the
article cited here:
http://www.gcn.com/vol1_no1/daily-updates/21493-1.html), the Health
Level 7 Reference Information Model xml text file is 6.6M.
Both of these standards, and many more will need to be compared and
best practices recommended for their use within the HPCDML. These are
not insignificant, and they point up the need to develop a way to
integrate these resources and navigate to the specific datatypes which
are appropriate to the application uses one requires. A partial list
of groups, their urls, associated specifications and brief
descriptions or self-descriptions where possible within reasonable
length limitations follows. Each entry is followed by an empty line
space.
This list is neither comprehensive nor exhuastive, but reflects the
current state of my personal knowledge as best I can assemble it in
mid-April 2003. Since clear and correct, or correctly namespaced,
Names for individuals and terms are of paramount concern, I list the
standards for this area first, beginning with Extensible Name Service
first because it is, along with ISO 11179, which defines the
specification and standardization of data elements, a key resource and
set of requirements for Names, Naming Conventions, associated
datamodels and datatypes and Naming-Related Information.

MARC is the acronym for MAchine-Readable Cataloging
It defines a data format which emerged from a Library of Congress led
initiative begun thirty years ago (in the 1970s). MARC became USMARC
in the 1980s and MARC 21 in the late 1990s. It provides the mechanism
by which computers exchange, use and interpret bibliographic
information and its data elements make up the foundation of most
library catalogs used today.The Network Development and
MARC Standards Office is a center for library and information network
standards and planning in the Library of Congress. Established in 1976
to provide focus for networking activities in the Library of Congress,
the office was expanded in 1984 to include MARC standards
responsibilities. To contact it, please e-mail:
