In the mid 1980s, Hugh was the chairman of the standardization committee on documentation and product data for the STEP standardization (ISO 10303), and through that activity was invited to participate in a project with Boeing Aircraft Co. was to provide SGML models and architecture for the multitudinous aircraft documentation in developing the concept of the Enterprise Wide Repository. This project was an initiative to consolidate all aircraft documentation (engineering, design, analysis, maintenance, etc.) in the Boeing concern, to standardize data formats for the purpose of interchange, interoperability and dissemination. Due to Boeing buying MacDonald Douglas, the project was never totally finished, but many interesting and valuable insights into aircraft documentation were realized. Boeing suggested that the work continue with an Airlines company with a Boeing fleet.

From 2001 to 2007, was involved in the EPHOS (European Procurement Handbook on Open Standards) project. was invited to consult on solutions for the system structure and data formats for the interactive EPHOS project. lead one project − authoring a complete section of the EPHOS project on the subject of Standard Structured Text – SGML. participated in teams authoring and editing several other sections.

For several years, was involved in the Volvo Car Co's project of converting maintenance manuals and technical documentation from various proprietary formats (WORD, WordPerfect, TEX, etc.) into SGML. I designed and programmed a set of transformation programs for converting technical data from various word processing formats and raw by analyzing the content and then automatically tagging it into SGML. This project converted 100's of thousands of pages of documentation into SGML.

During the time of developing SGML, I worked with parsing and developing diverse DTDs. The projects were numerous, but mainly conversions from text (WORD-type) into SGML. Many of these were large projects (involving conversion of 100s of thousands of pages), for equipment manufacturers, SAAB Military Aircraft, Boeing Aircraft Co.

was asked to head a committee that analysed Danish law texts and from the analysis results designed and implemented LexDania − a structured set of XML schemas for the development of law text specifications. It was to be used for interchange and interoperability as well as a format for storing, searching and print-formatting.

Working together with stakeholders from the Danish Parliament and the Ministry of Justice, I designed and implemented a set of XML schemas and RDF definitions that became the foundation of the LexDania system. The stakeholders represented different facets of the law text production, archiving, on-line access, etc., and provided a broad view on the user community. Consensus was reached within the project group and thereafter with the political stakeholders on a design of a radically new and different fundamental framework. The framework proposal replaced the original idea of creating many (estimates were about 157) different individual schemas. Instead, stakeholders could construct individual schemas for their own individual vocabularies and formatting applications, but all were based on underlying schema framework. Not only was it much easier to write schemas but all schemas were compatible at a usable and applicable level of granularity – as they were based on the same fundamental schemas. Thus, one data base structure could accommodate all applications, searching was greatly simplified, documentation was reduced to a basis plus individual application modifications, etc. As well, each stakeholder could, in a very short time (a day or two) create new schemas and/or modify old ones. Maintenance was reduced to working with a small set of hierarchical schemas rather than the 100s of individual schemas.

The system has been a great success and is now the accepted standard for not only law text but all official text within the Ministry of Justice. It is also being adopted by other Danish Ministries with the intention of becoming the Danish Ministerial standard for all official digital texts. Other countries, e.g., Italy and Switzerland as well as the EU have either adopted the schemas or are considering LexDania as a schema framework for their national law text specifications.

was engaged as a Enterprise Architect by the Danish Ministry of Education to develop a process to consolidate and re-engineer their legacy IT repository resources with a long term standardized approach. The purpose of the architecture was to strengthen the infrastructure and standardize information entities to enable interchange and eventually provide for interoperability.

The project was discontinued due to extraneous circumstances, but is included here as it was the inspiration to the project that has just completed.
