Dear Deb, I doubt it. I think the ontolog community could pay more attention than the organizations that made this and have done nothing with it...not that they don't want to in the current day and age...but it should be encoded in useful languages that could be linked to useful activities Developing standards requires a particular set of attributes, including authority. Ontolog is good for lots of things, but I will be absolutely amazed if it ever develops a standard. If there were problems with this standard, I suggest it is down to the process operated and the governance applied. My guess is that they were not one of ISO, IEEE, OMG, W3C, OASIS, which are standardisation bodies with appropriate processes and governance. That does not mean that Ontolog members might not contribute to developing standards. Common Logic is perhaps the best example. But that was developed with ISO.

As is true in any domain getting consensus on "the main elements" or a hierarchy at all is significant and it is past time for something to be done with this. Personally, given the vast spectrum how facilities data could be used, I like RDF and will look into some more examples of JSON in action.
The implementation is going to require more than one language - plus physical geometry. Thanks for the pointer to IKL and GML. Thanks for the feedback, will investigate

I think we need to encode the standard hierarchy (from world
to a bolt on a piece of equipment) in RDF plus OWL.
I agree with everything up to the last three words.
If the Semantic Webbers had done their duty a dozen years ago, we
wouldn't need all the preaching about how useful ontology could be.
But instead of focusing on semantics, they got bogged down in syntax.
The major web companies -- Google, Microsoft, Yahoo!, Amazon --
have rejected RDF and OWL. They'll accept input in RDF, but they
don't generate it, use it, or recommend it. If I were investing
my own money, I would not bet on RDF + OWL.
DM
I have a couple sample problems but want to get "the idealized
existing universe" in perspective first. For example, more precision
is needed for location from lat/long to navigating a floor (aka storey)
to a room, to a piece of equipment or sensor - then back out again
to the block, neighborhood, state with corresponding application domains
similar to places and spaces mapping science maps
You can represent simple data in triples, but OWL is too weak to do
the kind of reasoning required to support the above requirements.
If you look at the overwhelming majority of OWL ontologies on the web,
you'll find that they don't use anything beyond Aristotle. The biggest
difference is that Aristotle's notation was much better -- for both
people *and* computers.
JSON is much more widely used than RDF because it has more structure,
better typing, and a notation that is far more efficient for computers
and far more readable for humans. Any JSON triples can be extended
to n-tuples, they can have optional typing, they can be nested at any
depth to form lists, and they have a simple mapping to most programming
languages and most notations for first-order logic. JSON is also used
and recommended by Google, Microsoft, and Yahoo! -- they have more
power, more money, and more experience than the W3C. I'll bet on them.

Who is it that thinks that separate formalisms and tooling for semantic
web description logic, procedurally sequenced process models, and
aggregations of business rules provide an adequate conceptual framework
for, let alone a practical methodological foundation for
architecture/engineering/construction?
I strongly agree with the implications of that rhetorical question.
Among them is the need for common semantics.
Commercial compilers became available in the mid 1950s. By the mid
1960s, compiler technology was mature. Today, we have commercial and
open-source compilers that can take multiple programming languages as
input and generate multiple machine languages as output.
GCC, for example, can compile 7 programming languages as standard and
another 8 or 9, but not in the standard version. For output, GCC can
generate machine code for 20 major architectures, another 23 less
popular architectures, and 20 more that are processed by specialized
versions of GCC.
Furthermore, anybody who designs a new programming language or
a new machine architecture (hardware or virtual) can modify the
GCC source code to support it.
This means that syntax is a *solved problem* -- any and every syntax
that anybody finds useful (including RDF + OWL) can and should be
supported. But every syntax has a different "sweet spot". It is
foolish to force everybody to use the same syntax for all purposes.

Formal concept analysis (FCA) may then be directly applied.
http://en.wikipedia.org/wiki/Formal_concept_analysis
There are aspects of formal concept analysis and lattice theory
that may be applied across an wide range of topics using relations
as one guiding filter.
I strongly agree. FCA is a semantic technology that is independent
of any notation. It has been used successfully in conjunction with
RDF and OWL. But it has also been used with a wide variety of other
notations, logics, and programming languages.
FCA avoids getting bogged down in battles about syntax. It is not
rich enough to support all requirements for reasoning, but it
supports a large subset of OWL by *automatically* generating the
hierarchy of concepts (AKA classes) without requiring somebody
to do the detailed coding in OWL. I'll bet on FCA.
The critical issue is semantics. For GCC, the semantics is defined
by an abstract machine. All source languages are compiled to an
Interlingua that corresponds to that machine. All target languages
are generated from that Interlingua.
For logic, the ISO 24707 standard for Common Logic was designed as
an Interlingua. DoD funded the IKRIS project, which recommended
one additional feature to CL for the IKL language. The IKRIS
project also demonstrated that IKL could serve as an Interlingua
among several very rich knowledge representation languages,
including CycL, which is the language used for the biggest formal
ontology ever implemented and used.
RDF and OWL are small subsets of Common Logic, with some built-in
ontology that is easy to define in CL. JSON, predicate calculus,
and many other common notations are also simple subsets.
But I am *not* claiming that CL or IKL is an absolute requirement.
What I am saying is that a common semantics is required. If anybody
finds or defines a semantics that is better suited than CL or IKL,
I would be delighted to support it.
The first priority is a common semantics. The second priority
is to evaluate proposals. CL is an example. The IKRIS committee
recommended CL with one extension for IKL. If anybody has a better
suggestion -- either a replacement or a modification to CL or IKL
-- then we should consider it.

There are efforts underway to standardize the application of
ws-calendar schedules to mission functions (i.e. material
in the Program phase) to understand not just how much energy
will be required, but when.
That's a typical application. And most application domains have
traditional notations that the users and developers prefer. It
is counterproductive to force people to shoe-horn their preferred
notations to something like RDF and OWL. Instead, their notations
should be compiled directly to the common semantics.
The Cyc project has over 27 years of experience in translating
input from a wide variety of different notations to CycL. That
experience is valuable, and most of it is documented in white
papers on the cyc.com web site. We should take advantage of it.
I would also recommend the dissertation by Tara Athan, who used
the IKL semantics to support knowledge interchange with the
Geography Markup Language (GML). See the abstract below.

XCLX: An XML-based Common Logic eXtension
with Embedded Geography Markup Language
Mary E. Athan
A novel eXtensible Markup Language (XML)-based Common Logic eXtension,
called XCLX, is presented. The novel syntax draws from the standard
syntaxes Common Logic Interchange Format (CLIF) and eXtended Common
Logic Markup Language (XCL), as well as Rule Markup Language (RuleML),
Interoperable Knowledge representation Language (IKL), IKRIS Context
Language (ICL), and XML Inclusions (XInclude). In addition, the syntax
is open to user extensions, including embedding elements from foreign
namespaces as names, functions and atomic sentences, and has a meta-
language for self-extensibility. These features allow Common Logic to
embed structured data, such as Geography Markup Language (GML), while
maintaining a well-defined semantics. The overall syntax is defined
by a modular schema, using a design pattern developed for RuleML.
The XCLX semantics is defined either by formal mappings into equivalent
syntactic forms (in XCLX or foreign dialects, including CLIF, IKL,
ICL), or axiomatically through the meta-language. The semantics of
the meta-language is novel and is stated directly. A number of
illustrative examples, drawn from geography and GML, are presented.
