Preface
It seems like ages ago when I stared out of a window facing the spectacular Monterrey Bay mid-afternoon, watching a couple of dolphins play in the surf, mulling over presentation slides from the EDOC 2004 (IEEE Enterprise Computing) workshop on Model-Driven Semantic Web. The aim of the workshop is to bridge knowledge representation and Model Driven Architecture (MDA) methodology

for Software Engineering. At the time, what is now “OWL 1” was about to be published as a W3C recommendation. Several of us who participated in that EDOC workshop had been haggling over language nuances and their interpretation in Unified modelling Language (UML) for the Ontology Definition Metamodel (ODM)

) for more than a year.
Today we continue to challenge one another as we integrate changes to support OWL 2, revising the mappings to take advantage of a new generation of Query, Views, and Transformation (QVT)

tooling and incorporating lessons learned. The voices on the phone have changed, with a larger and in some ways more passionate team than ever participating. In other words, the signs are promising. The work is at least as relevant today as when we set out, with a rapidly expanding and broader-based community of stakeholders, with domains ranging from systems engineering to financial services and healthcare, looking to us for leadership and for results.
Independently, starting at about the same time as we launched our ODM effort at the Object Management Group Jeff Z. Pan, Evan Wallace, Phil Tetlow, Holger Knublauch, Mike Uschold, and others in the Semantic Web Best Practices and Deployment working group started thinking about applying semantics to Software Engineering, with Jeff and Phil being the coordinators of this W3C Software Engineering task force. I met Jeff face to face for the first time in Galway in 2005, just prior to our first Semantic Web Enabled Software Engineering (SWESE) workshop, but had been talking with him and others about semantically enabled Software Engineering for more than a year by then, within the W3C task force. Between the discussions in the task force and how well the EDOC workshop was received, we realized that we had an opportunity and, in fact, a responsibility, to nurture and grow the community. Thankfully, Jeff was happy to participate as an organizer, and has been instrumental in promoting and managing the workshop since. The work that he and his colleagues, including Yuting Zhao, who jumped into the SWESE effort a couple of years later, have done on the EU MOST (Marrying Ontology and Software Technologies) project on reasoning and guidance frameworks for ontology driven software development, has made a tremendous contribution to the SWESE series and to the state of the art.
SWESE provides a window on the work that people have done to bring Software Engineering and semantic technologies together to solve critical problems, including and since that first workshop; it represents the best thinking produced by the community over the course of the series. The material ranges from foundational – reminding us of the motivation, underlying technologies, and how we bridge the gap from semantics to Software Engineering and MDA in part I, to realization through a number of important, early projects in part II, and finally presents several supporting ontologies that continue to have relevance today in part III. The book represents acknowledgement of the start of something big. It reminds me of critical findings and foundational work that we need to continue to build on, as we prioritize development of the standards and best practices going forward. It is a cornerstone for new and evolving fundamental research and development, as well as instructional material for use in educating our peers and students.
Recently I attended an Object Management Group (OMG) technical meeting in Washington DC, the first held there in two years. On my way home, I thought back to the first OMG meeting I spoke at in 2001, and what a lunatic folks there thought I was at the time. I admit that they were probably right, but given how many people in banking and financial services, including government regulators, sat spellbound through a presentation on a new ontology project describing the capital market domain and its applications, I am finally feeling a bit like the Cheshire cat. And yet, I firmly believe that what we can do with semantics in Software Engineering is barely understood, still in its infancy from a research perspective. SWESE represents the proverbial tip of the iceberg. I am honoured to be counted among the contributors to this work and pleased to introduce it.
