Defining a formal domain ontology is generally considered a useful, not to say necessary step in almost every software project. This is because software deals with ideas rather than with self-evident physical artefacts. However, this development step is hardly ever done, as ontologies rely on well-defined and semantically powerful AI concepts such as description logics or rule-based systems, and most software engineers are largely unfamiliar with these. Gaševic and his co-authors try to fill this gap by detailing how to use model-driven engineering for ontology development on the Semantic Web. Part I of their book describes existing technologies, tools, and standards like XML, RDF, OWL, MDA, and UML. Part II presents the first detailed description of OMG's new ODM (Ontology Definition Metamodel) initiative, a specification which is expected to be in the form of an OMG language like UML. Finally, Part III is dedicated to applications and practical aspects of developing ontologies using MDA-based languages. For this second edition, the descriptions of the related standards (like MOF, ODM, OCL, and OWL) have been revised and updated; new chapters introducing the basic principles of model-driven engineering, recent research results on metamodeling Semantic Web rule languages, an introduction to the Atlas Transformation Language (ATL) and its tool support, and, last but not least, many new examples have been added.

This report explores why, in recent decades, military fixed-wing aircraft costs have escalated beyond the rates of commonly used inflation indices, examining both economy-driven factors that the Services cannot control and customer-driven ones that they can. The authors found that this trend of cost increases is true for all types of aircraft
Welcome to United in Victory Church. Referred to by many as 'United in Victory Tabernacle on the Hill Freewill, Baptist, Catholic and Episcopal Church of God in Christ, ' because of the church's diverse make-up, the church was founded in 1956 by Bishop Al. B. Wright Just, Sr. From its inception until now, United in Victory's congregation is intricately woven into its historical quilt. Members come with their own distinctive set of traits and personalities. Some are living, while others are deceased. Some joined the church and stayed, while others joined the church and left. Whatever the circumstance, each congregant has contributed their own unique fiber to the church's colorful patchwork. Within the walls of this fictional church world lies beauty and betrayal, friction and feuds, hymns and mayhem, holiness and haughtiness, malice and miracles, sanctity and scandal, set-ups and cover-ups, sin and salvation, The Gospel and gossip, and temptation and triumph. Secrets have stayed hushed and gossiped about for generations amongst the congregation's intriguing and unforgettable characters. But now...the untold stories are being told. From the Annals of United in Victory Church, comes the first of the United in Victory Book Series, the story of Serenity House: From Addiction to Deliverance.
Congress asked RAND for an independent review of whether the estimated savings from proposed multiyear contracts for 60 F-22A aircraft over three years would yield the promised savings. Researchers found that a multiyear procurement of three lots of F-22A fighters would save an estimated $411 million-about 4.5 percent of the total contract value-and that savings attributed to the multiyear contract by the contractors appear to be reasonable.
