Resource Oriented Modelling: Describing Restful Web Services Using Collaboration Diagrams
The popularity of Resource Oriented and RESTful Web Services is increasing rapidly. In these, resources are key actors in the interfaces, in contrast to other approaches where services, messages or objects are. This distinctive feature necessitates a new approach for modelling RESTful interfaces providing a more intuitive mapping from model to implementation than could be achieved with non-resource methods. With this objective we propose an approach to describe Resource Oriented and RESTful Web Services based on UML collaboration diagrams. Then use it to model scenarios from several problem domains, arguing that Resource Oriented and RESTful Web Services can be used in systems which go beyond ad-hoc integration. Using the scenarios we demonstrate how the approach is useful for: eliciting domain ontologies; identifying recurring patterns; and capturing static and dynamic aspects of the interface
Towards Compliance of Cross-Organizational Processes and their Changes
Businesses require the ability to rapidly implement new processes and to quickly adapt existing ones to environmental changes including the optimization of their interactions with partners and customers. However, changes of either intra- or cross-organizational processes must not be done in an uncontrolled manner. In particular, processes
are increasingly subject to compliance rules that usually stem from security constraints, corporate guidelines, standards, and laws. These compliance rules have to be considered when modeling business processes and changing existing ones. While change and compliance have been extensively discussed for intra-organizational business processes, albeit only in an isolated manner, their combination in the context of cross-organizational processes remains an open issue. In this paper, we discuss requirements and challenges to be tackled in order to ensure that changes of cross-organizational business processes preserve compliance with imposed regulations, standards and laws
Detecting semantically related concepts in a SOA integration scenario
In this paper, we present an approach to detecting semantically related
concepts in a service oriented environment. This method is essential when
creating collaborative business processes. Standard enterprise application
systems such as enterprise resource planning (ERP), customer relationship
management (CRM), supply chain management (SCM) etc. offer a lot of
opportunities for application interoperability. System integrators assign a
set of services from various application systems to the integration
scenario. A well defined discovery process can detect these services.
Nevertheless, building an operable business process requires the mapping of
these services in the data schema used in the business process. This mapping
results in a global understanding of relevant business concepts in the
integration scenario. This paper focuses on the identification of
semantically relevant concepts in different schemas in the participating
services. A short overview of our integration platform and methodology is
also included
Detecting the Effects of Changes on the Compliance of Cross-organizational Business Processes
An emerging challenge for collaborating business partners is to properly define and evolve their cross-organizational processes with respect to imposed global compliance rules. Since compliance verification is known to be very costly, reducing the number of compliance rules to be rechecked in the context of process changes will be crucial. Opposed to intra-organizational processes, however, change effects cannot be easily assessed in such distributed scenarios, where partners only provide restricted public views and assertions on their private processes. Even if local process changes are invisible to partners, they might affect the compliance of the cross-organizational process with the mentioned rules. This paper provides an approach for ensuring compliance when evolving a cross-organizational process. For this purpose, we construct qualified dependency graphs expressing relationships between process activities, process assertions, and compliance rules. Based on such graphs, we are able to determine the subset of compliance rules that might be affected by a particular change. Altogether, our approach increases the efficiency of compliance checking in cross-organizational settings
Change and Compliance in Collaborative Processes
During their lifecycle, business processes are keen
to change. Changes either concern the process model structure or the accompanying rules; e.g. compliance rules (laws and regulations). In the context of business process collaborations, several process partners collaborate together, and changing one process might result in knock-on effects on the other processes; i.e., change propagation. Since business processes are often subject to restrictions that stem from laws, regulations or guidelines; i.e., compliance rules, changing them might lead to the violations
of these rules (non-compliability). So far, only the impacts of process changes in choreographies have been studied. In this work, we propose an approach that analyzes and evaluates the impacts of process changes on the different compliance rules and inversely, the impacts of compliance rule changes on the process choreography
Ensuring Compliance of Distributed and Collaborative Workflows
Automated workflows must comply with domain-specific regulations, standards and rules. So far, compliance issues have been mainly addressed in the context of intra-organizational workflows. In turn, there exists only little work dealing with compliance of distributed and collaborative workflows. As opposed to intra-organizational workflows, for distributed and collaborative workflows compliance must be addressed at different levels. This includes local compliance rules of a particular partner as well as global compliance rules to be obeyed by multiple partners collaborating in the distributed workflow. As a particular challenge, the private elements of a particular partner workflow are hidden to the partners and hence not known by them. Accordingly, only limited information is available when checking compliance of distributed and collaborative workflows. This paper introduces techniques enabling compliance checking for distributed and collaborative workflows, taking these privacy constraints into account. Hence it enables ensuring compliance of distributed and collaborative workflows at design time
On Enabling Compliance of Cross-Organizational Business Processes
Process compliance deals with the ability of a company to ensure that its business processes comply with domain-specific regulations and rules. So far, compliance issues have been mainly addressed for intra-organizational business processes, whereas there exists only little work dealing with compliance in the context of cross-organizational processes that involve multiple business partners. As opposed to intra-organizational processes, for a cross-organizational process, compliance must be addressed at different modeling levels, ranging from interaction models to public process models to private processes of the partners. Accordingly, there exist different levels for modeling compliance rules. In particular, we distinguish between local compliance rules of a particular partner and global compliance rules to be obeyed by all partners involved in the cross-organizational process. This paper focuses on checking the compliance of interaction models. For this purpose, we introduce the notion of compliability, which shall guarantee that an interaction model is not conflicting with a set of imposed global compliance rules
A flexible approach for automatic process decentralization using dependency tables
International audienceWeb service paradigm and related technologies have provided favorable means for the realization of collaborative business processes. From both conceptual and implementation points of view, the business processes are based on a centralized management approach. Nevertheless, it is very well known that the enterprise-wide process management where processes may span multiple organizational units requires particular considerations on scalability, heterogeneity, availability and privacy issues, that in turn, require particular consideration on decentralization. In this paper, our aim is to reconcile the decentralization of processes as a step towards the enterprise-wide solutions. We propose a methodology for transforming a centralized process specification into a form that is amenable to a distributed execution and to incorporate the necessary synchronization between different processing entities. The proposed technique has the advantage of being flexible that it computes the abstract constructs and provides a generalized approach to the decentralization of processes
