Implementing an extended SQL for NoSQL databases is possible and is extremely useful. This requires extensions to SQL like those proposed in context of NF2 relations without assuming a global schema. This is not against the nature of SQL at all and outlines a clear path forward for databases to provide a declarative query language implementation fo...
Conference Paper
RoboBrain proposes a biologically inspired 'blue-print' software architecture for humanoid robots that maps the main functions of the human brain. Given the extreme complexity of designing such an architecture, our intention is to provide a basic robots' IT command and control foundation with minimal required components to address humanoid robots'...

This extended abstract summarizes the state-of-the-art solution to the structuring problem for models that describe existing real world or envisioned processes. Special attention is devoted to models that allow for the true concurrency semantics. Given a model of a process, the structuring problem deals with answering the question of whether there...
Article
XML-based standards have been widely used to enable and ease Business-to-Business (B2B) integration. Examples of standards include cXML, CIDX and ebXML. While these XML-based standards are syntactic, contemporary organizations have available new means to structure their internal data representations using semantic descriptions, such as RDF(S) and O...
Chapter
As long as businesses only have one enterprise application or back end application system there is no need to share data with any other system in the company. All data that has to be managed is contained within one back end application system and its database. However, as businesses grow, more back end application systems find their way into their...

The METEOR-S and WSMO projects deal with the lifecycle Semantic Web services and processes. Though, they are separate projects with different approaches, we have identified points of interoperability between them. In this paper, we describe the projects and present the points of interoperability. We intend this work as a starting point for the Sema...
Article
Issues of trust, reliability, and data heterogeneity make it unlikely that we'll have access to a set of free and heterogenous Web services and tools to combine them on the Internet anytime soon. The authors contend, instead, that "service parks" will rise and succeed in the near future as execution environments that support simplified data integra...
Article
Full-text available
Although the Semantic Web vision has spawned an entire academic discipline and considerable research and development effort is focused on the subject, the results are much less impressive in terms of actual applications. Bussler’s architectural analysis suggests why and that SWT is headed for a disaster unless there is a change of course.

Full-text available
It is a fair question to ask whether or not services, ontologies, and mobility all thrown together in one issue will make a strange and somewhat arbitrary mix of themes. As we will demonstrate in this article, this is most definitely not the case. In the contrary, it is our belief that only the combination of ontologies and services will provide an...
Chapter
In the introduction of this book we wrote: “The Semantic Web is a vision: the idea of having data on the Web defined and linked in a way that it can be used by machines not just for display purposes, but for automation, integration and reuse of data across various applications. The goal of the Semantic Web initiative is as broad as that of the Web:...
Chapter
Ontologies are a critical component of the Semantic Web architecture. In this chapter, we present a discussion on various aspects of ontology authoring and management. We discuss a collection of ontology building tools and present an evaluation across various dimensions. A brief discussion on techniques for boostrapping of ontologies is presented a...
Chapter
We present a discussion of various ontology and schema-like artifacts used in various fields of activity such as library sciences, relational databases, knowledge representation and medical informatics. We then discuss languages proposed for representation of ontologies and schemas such as XML Schema [87], RDF Schema [88] and OWL [54] and present a...
Chapter
We now revisit functional requirements presented in Chapter 2 and illustrate them with examples based on the use case. We begin with a simplified clinical workflow in Figure 13.1 (which is an adaptation of Figure 2.1). This process is used as a (simplified) entry point into the translational medicine use case discussed earlier.
Chapter
As in many areas it is important to work on standardization to allow widespread development of interoperable software. In the end, this is what counts as success. Consequently, the Semantic Web communities engaged in this process through various means are presented in this chapter.
Chapter
Web Services are often invoked in isolation, meaning, a Web Service operation provided by a Web Service provider is invoked by a Web Service requester. Based on the input message, the operation provides the result in form of an output message. However, in many cases an individual invocation is insufficient to achieve a more complicated communicatio...
Chapter
In this chapter, we begin with an understanding of the nature of data and content available on the web today and discuss preliminary approaches for representing metadata. We will then methodically enumerate and discuss various types of Semantic Web content spanning structured, unstructured and semi-structured data, with examples from the healthcare...
Chapter
A key value proposition enabled by the use of metadata descriptios based on concepts from domain specific ontologies, is the ability to describe Web and other types of content using semantic descriptions with fine grained abstractions. These descriptions could appear in the form of annotations in the case of unstructured data. Alternatively, in the...

Conference Paper
Conceptually it is tempting to declare every piece of functionality a service, put all services on an asynchronous enterprise service bus or queuing system, compose these services into meaningful business logic and provide all services at runtime for execution. Real information technology environments are, however, not that simple and require an ap...

Conventional wisdom holds that the service-oriented architecture approach is the silver bullet for all IT problems nowadays. According to this view, SOA leads to near-perfect applications in which every function is implemented as a service, and a service can call any other service to implement its functionality. This includes not only services that...
