Integration of rules and policies for Semantic Web Services

Abstract

Multimedia service providers on the web need their services to be well protected and easily accessible worldwide. This has initiated several lines of research to provide semantically rich policy-aware web services. However, the existence of various technologies to define and protect services has made the communication of services questionable. Currently, it is ambiguous how a broker agent looking for a special object would communicate to an online service provider, with different policy and service definition languages, to obtain the appropriate object. Here, we propose a solution to such problems by introducing an interchange framework to transform business rules and policies between different enterprises using REWERSE Rule Markup Language.

Web Rule Languages to Carry Policies

“…Nevertheless, to the best of our knowledge, there is still no real work done by the Policy RuleML technical committee in this area. In the next section, we explain our efforts to address these goals by using R2ML [12].…”

“…In this paper, we propose an approach to sharing policies by using Web rule languages [12]. This actually follows up two initiatives: the Rule Interchange Format (RIF) [6], an initiative for the standard for sharing rules on the Web, and Policy RuleML [20], an initiative for sharing policies by using various types of rules (e.g., derivation and production) of the RuleML language [8].…”

Modeling Semantic Web Services using UML 2

“…It is only applicable to OWL-S and misses transformation rules for other approaches. [17] describes how semantic web services and policies can be modeled using the REWERSE Rule Markup Language (R2ML). [18] develops an MDD annotation methodology for semantic enhanced SOAs, but does not develop a UML profile for semantic web services in greater detail.…”

Especificación del comportamiento de gestión de red mediante ontologías

“…Algunos estándares propuestos son OWL-S (descrito en el Cap. 5), WSDL-S, y Web Service Modelling Ontology [Kaviani06]. En [LopezDeVergara05] se muestran algunas de las ventajas de aplicar la ontología OWL-S para la definición de operaciones de gestión de red, que se detallarán más adelante.…”

“…Esto permite en tiempo real, el descubrimiento, composición, y orquestado (o coreografía) de servicios Web mediante la definición de pre-condiciones y post-condiciones para todos los mensajes intercambiados durante el proceso de ejecución del servicio. Por ejemplo, OWL-S recomienda la utilización de ontologías OWL junto con diferentes lenguajes de reglas (SWRL, KIF, o DRS), WSMO utiliza F-Logic, mientras que WSDL-S no indica preferencia alguna al respecto [Kaviani06].…”
