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.

Ga evic and his co-authors try to fill this gap by covering the subject of MDA application for ontology development on the...

We are pleased to present the proceedings of the First International Conf- ence on Software LanguageEngineering (SLE 2008). The conference was held in th Toulouse, FranceduringSeptember29-30,2008andwasco-locatedwiththe11 IEEE/ACM International Conference on Model-Driven Engineering Languages and Systems (MODELS 2008). The SLE conference series is devoted to a wide range of topics related to arti?cial languages in software engineering. SLE is an international research forum that brings together researchers and practitioners from both industry and academia to expand the frontiers of software...

According to the W3C Semantic Web Activity 1]: The Semantic Web provides a common framework that allows data to be shared and reused across appli- tion, enterprise, and community boundaries. This statement clearly explains that the Semantic Web is about data sharing. Currently, the Web uses hyperlinks to connect Web pages. The Semantic Web goes beyond that and focuses on data and envisions the creation of the web of data. On the Semantic Web, anyone can say anything about any resource on the Web. This is fully based on the concept of semantic - notations, where each resource on the Web can...
