A common challenge to Prognostic Health Management (PHM)
systems is the management of data across different organi-
zations based on a standardized format and meaning. The
Open System Architecture for Condition-based Maintenance
(OSA-CBM) and the Open System Architecture for Enter-
prise Application Integration (OSA-EAI) are complementary
reference architectures for domain-independent asset and con-
dition data management. In previous papers, we reported on
our experiences with implementing a data integration layer
based on these two architectures. In this paper, we report
on our experience implementing code generators for binary
OSA-CBM and OSA-EAI Tech-CDE (Compound Document
Exchange), and the utilization of the resulting components
within the OMAHA project. OMAHA aims towards an over-
all management architecture for health analysis, incorporat-
ing manufacturers, operators and maintainers of fleets of air-
craft. The OSA-CBM standard specifies a message structure
but leaves the assembly and disassembly of OSA-CBM data
up to the implementor. Our solution is a builder/reader Appli-
cation Programming Interface (API) for a binary OSA-CBM
message codec which we have implemented under the con-
straints of a real-time computing environment. The required
C code is automatically generated from the provided tech-
nical documentation for OSA-CBM. We discuss the prop-
erties of the resulting codec and point out future improve-
ments for the OSA-CBM binary protocol to improve consis-
tency and to add the capability of streaming. Using the same
generative approach we have implemented a code generator
for a Tech-CDE-compliant middleware system, consisting of
client libraries (currently C++ and Java), a network layer,
a server portion, and a database backend. Analogously to
OSA-CBM, the code generator processes the documentation
provided for Tech-CDE, creating both productive and test-
ing code. We discuss the properties of the resulting system,
report specific limitations of the Tech-CDE protocol and sug-
gest mitigations. The paper concludes with an experience re-
port from utilizing our work in the OMAHA project. While
Tech-CDE was generally found sufficient, we identified ar-
eas of improvement, including protocol properties and entity
coverage. We were able to make customizations using our
generative coding approach and present these as suggestions
for future standard extensions.
