This work presents an extension of the Belgrade ACol collisional database within the Virtual Atomic and Molecular Data Centre (VAMDC) framework to include dissociative electron attachment (DEA) processes. DEA, a low-energy electron-driven resonant mechanism leading to molecular fragmentation, is relevant in fields such as plasma science, radiation damage, nanofabrication, and EUV lithography. The ACol data model was redesigned to improve semantic clarity and flexibility by separating physical collision data from bibliographic and serialization structures. A new DataSource entity and a redefined TabulatedData–Collision relationship enable a more normalized database while preserving compatibility with the XSAMS schema through dynamic, query-time construction of hierarchical structures. The implementation is demonstrated using DEA to isoflurane, incorporating experimental data from independent studies and cataloging resulting fragment anions and energy-dependent yields. Elastic cross sections of isoflurane are included as they are immanently connected to DEA, providing an essential tool for understanding the complex DEA process. The novelty of the present implementation lies not in the first representation of DEA within VAMDC, but in its integration into a multi-process collision database based on a compact, normalized data model that separates scientific data and bibliographic provenance from the XSAMS serialization structure. The updated architecture enhances interoperability, reduces redundancy, and improves data management while maintaining compliance with VAMDC standards.

To facilitate the vision of service-oriented manufacturing, Cloud Manufacturing (CMfg) will need to support business process model life-cycle management. In this paper, we propose the Business Process Cataloging and Classification System (BPCCS) to support that role. BPCCS can facilitate adaptation of business process models. We validate life-cycle management requirements for such a system and propose capabilities the system must have to address these requirements. We analyze related work in academia and industry as a basis for synthesizing a meta-model and a conceptual architecture for the system. We conclude that contextual information for business process models is a critical part of such a system and where the CMfg community can contribute new and valuable results.

Business Process Modeling Notation (BPMN) is being adopted as one of the industry standards for modeling cross-organizational business processes (CBPs). BPMN analyzes a business process as a set of interrelated activities, focusing primarily on the functional perspective of the process. However, for successful CBP modeling, an informational perspective is important. Although BPMN 2.0 supports information flow design, existing representations of data/information elements are not sufficient to support CBP modeling requirements. In this light, the paper proposes an approach for formal modeling and specification of information requirements used and generated in the CBPs. A UML View Profile is introduced to specify information requirements as views over the common reference ontology. A BPMN 2.0 extension is introduced to connect the defined views and the corresponding process activities. Ultimately, the proposed information requirements specification enables generation of the message instance and its transformation at the implementation level.

Weaving models are used in the model driven engineering (MDE) community for various application scenarios related to model mappings. However, an analysis of its suitability for specification of heterogeneous schema mappings reveals that weaving models lack support for mapping rules and, therefore, cannot prevent mapping specifications which are semantically meaningless, wrong or disallowed. This paper proposes a solution which overcomes the identified open issue by providing the explicit support for semantic mapping rules. It is based on introduction of weaving metamodels augmented with constraints written in OCL. The role of OCL constraints is to restrict mapping specifications to only those which are semantically meaningful. Using well known MDE technologies, such as EMF and QVT, an existing tool is used to validate the presented solution. This solution is also successfully evaluated in practice.

This paper investigates the potential of the Semantic Web technologies to support a semantic-based Enterprise Application Integration (EAI) standards architecture. We give detailed information of the support that these technologies and the underlying Description Logics (DL) formalism provide for the integration task. Our main aim is to assess the potential impact of these emerging technologies on industrial interoperability efforts. In addition to that effect, we plan to use this advanced EAI standards architecture as an experimental framework in which the Semantic Web technologies are evaluated on realistic enterprise integration problems. We illustrate novel capabilities beyond the existing syntactic integration approaches when managing multiple enterprise ontologies derived from a common ontology.
