When trying to compose services that are developed according to different standards, interoperability issues arise that are often faced by developing ad-hoc solutions. A typical example is represented by the composition of W3C and OGC services, which were developed more or less concurrently by independent organizations. In such a context, developing a wrapper that abstracts as much as possible the inner details and logic of a wrapped service well embraces the low-coupled nature of the general Service Oriented Computing paradigm. This paper focuses on the proper management of geospatial metadata into a W3C-based environment and is based on the development of a wrapper that exposes OGC functionality in a W3C-compliant way, thus overcoming the technical differences between the two types of services. To efficiently accomplish this task, a flexible, wrapper-based, and standard-compliant mechanism for metadata retrieval is proposed that avoids the use of third-party entities. The proposal exploits the scalable and adaptable nature of the WS-Metadata (Web Services Metadata) specification.
