The allocation of clinical resources for healthcare processes in a transactional (atomic) way is a complex task. It requires the cooperation of heterogeneous medical information systems that are typically based on proprietary solutions, developed in piecemeal way, and tightly coupled through ad hoc means. In addition, the resources required for a health care process have mutual timing constraints, which further complicate resource allocation. In this paper we have restricted on these problems. In order to achieve the semantic interoperability between the managers of the clinical resources, we have developed a resource ontology, which constitutes the vocabulary for the exchanged reservation messages. The resource ontology is specified by OWL, and the content of the exchanged messages are presented in RDF. The resource allocation processes are specified by Business Process Modeling Notation (BPMN). We have also developed a specific transaction model for atomic compositions of resource allocations, i.e., it ensures that all or none of the requested resources are reserved. The gain of using this transaction model is that we can avoid the cancelations of the resources allocations that are caused by the unrealized timing constraints.
