Curriculum Vitae — David Leal
The first part of David Leal's career was spent in the mathematical analysis of systems — control systems and structural systems. In this part of his career he developed a major framework and finite element analysis system, and used this system and other commercial systems to conduct safety critical analyses for the civil, offshore and nuclear industries.
The second part of David Leal's career has been concerned with the management of engineering data. He has been concerned with the development of ontologies and data models for engineering for use in both commercial applications and standards. These ontologies and data models have been in the areas of:
David Leal was an early promoter of the use of OWL for engineering data. His recent work has involved the creation ontologies and data models in OWL, EXPRESS and UML. Because of his long term work in standardization, he is able to write clear natural language text definitions.
BA Mathematics, University of Cambridge
MSc Systems Engineering, The City University, London
The City University — researcher
Conducted research into the identification of parameters in system models on the basis of uncertain observations, especially for the Steam Generating Heavy Water Reactor, under contract to the UK Atomic Energy Authority.
CCS (Specialist software house owned by a consortium of UK consulting engineers)
Developed software for static and dynamic structural analysis.
Carried out research into the analysis of the dynamic response of pipework when subjected to earthquake loads.
SIA (Computer bureau and software house)
Team leader for the development of the LEAP5 engineering analysis suite. This software pioneered the use of relational data bases for engineering analysis data and was widely used for framework and finite element analysis in civil engineering for more than twenty years.
Central Electricity Generating Board (CEGB)
Performed finite element analyses for nuclear power station safety cases. Whilst at the CEGB, I became involved with the problem of long term archiving of engineering analysis data and in the role of standards. I became the CEGB representative on BSI AMT4/3, which jointly with the NAFEMS CAD-FE Working Group was responsible for engineering analysis data standards. I also became a BSI representative on ISO TC 184/SC4 "Industrial data".
1990 - present:
CAESAR Systems Limited
I founded CAESAR Systems to provide consultancy in engineering data management and standards. At CAESAR Systems, I have been involved with the following major projects:
I am a founder member of the NAFEMS CAD-FE Working Group, and initially represented the CEGB. This group has promoted the use of standards and information integration technologies within the engineering analysis community.
I represent NAFEMS on BSI committee AMT4, and am a UK Principal Expert on ISO TC184/SC4, working in the teams on engineering analysis and process plant. I am also co-convenor of the ISO TC184/SC4 "Industrial Data on the Web" team.
Working within the S-TEN project, I was one of the initiators of the W3C Product Modelling "Incubator Group".
I am leader of the "Future SC4 architecture" team within ISO TC184/SC4 which is developing a new architecture for the ISO TC184SC4 standards and in particular ISO 10303 (STEP). The new architecture will integrate dictionaries and ontologies with schemas. The new architecture will also support semantic web and web services implementation as well as the existing XML file and data base implementations.
The draft architecture specification is "Industrial Data Integrated Ontologies and Models" (IDIOM).
I was editor of the ISO/TS 15926-4 "Lifecycle data for the process industry &mdsh; initial reference data". This standard is now migrating from the traditional ISO publication route to the new ISO "Procedure for the development and maintenance of standards in database format".
I am editor of the ISO/TS 15926-6 "Lifecycle data for the process industry — Methodology for the development and validation of reference data".
I am leading the technical work on the proposed the ISO/TS 15926-12 for the OWL implementation of ISO 15926.
