Verma, 2004), and WSMO (2005), and associated initiatives such as SWWS (2005),<br />

SWSI/SWSA (2005), and interoperability initiatives between some <strong>of</strong> <strong>the</strong>se (Lara,<br />

Roman, Polleres, & Fensel, 2004; Paolucci, Srinivasan, & Sycara, 2004). WSMO<br />

and several related activities are being performed within <strong>the</strong> European Adaptive<br />

Services Grid (ASG, 2005) project. CASCOM European project (2005) also can<br />

be mentioned as one <strong>of</strong> <strong>the</strong> significant projects <strong>of</strong> <strong>the</strong> concerned domain, which is<br />

based on an interdisciplinary combination <strong>of</strong> intelligent agent, <strong>Semantic</strong> <strong>Web</strong>, peerto-peer,<br />

and mobile computing technologies.<br />

One <strong>of</strong> <strong>the</strong> domains, where knowledge accumulation and its timely delivery are<br />

crucial, is industrial maintenance (Automation, 2003). Development <strong>of</strong> a global<br />

environment, which would support automation <strong>of</strong> knowledge management for<br />

industrial maintenance, is a very pr<strong>of</strong>it-promising and challenging task. The latter<br />

is what <strong>the</strong> SmartResource 1 project aims at in <strong>the</strong> research and development efforts<br />

<strong>of</strong> Industrial Ontologies Group. 2<br />

The intention <strong>of</strong> <strong>the</strong> SmartResource team is to provide tools and solutions to make<br />

heterogeneous industrial resources (files, documents, services, devices, processes,<br />

systems, human experts, etc.) <strong>Web</strong>-accessible, proactive, and cooperative in a sense<br />

that <strong>the</strong>y will be able to analyze <strong>the</strong>ir state independently from o<strong>the</strong>r systems or to<br />

order such analysis from remote experts or <strong>Web</strong> services in order to be aware <strong>of</strong> <strong>the</strong>ir<br />

own condition and to plan behavior toward effective and predictive maintenance.<br />

This chapter presents an approach and a case study performed by <strong>the</strong> SmartResource<br />

team within an industrial maintenance domain aimed to design a possible<br />

architecture for interoperability <strong>of</strong> heterogeneous industrial resources, based on<br />

<strong>Semantic</strong> <strong>Web</strong> standards. Emphasis is made on a General Adaptation Framework,<br />

which is envisioned to enable reusable solutions and components for automatic<br />

adaptation <strong>of</strong> different types <strong>of</strong> resources and <strong>the</strong>ir data formats to <strong>the</strong> <strong>Semantic</strong><br />

<strong>Web</strong> environment.<br />

The structure <strong>of</strong> <strong>the</strong> fur<strong>the</strong>r content is <strong>the</strong> following. The next section introduces a<br />

global understanding environment as a background concept for future implementation<br />

and also briefly describes stages <strong>of</strong> architectural design for it. The third section<br />

provides more design and implementation details about <strong>the</strong> Adaptation Stage for <strong>the</strong><br />

target environment design. Then <strong>the</strong> general approach to building semantic adapters<br />

for industrial resources is given. The section describes <strong>the</strong> challenge itself, goes<br />

deeper into <strong>the</strong> details <strong>of</strong> <strong>the</strong> two-stage transformations between data models, and<br />

presents its pilot implementation results for a use-case scenario. The fifth section<br />

contains conclusions that follow from <strong>the</strong> performed research and development,<br />

and finally, <strong>the</strong> last section comprises additional discussion around <strong>the</strong> work done:<br />

practical usability <strong>of</strong> <strong>the</strong> results, <strong>the</strong>ir possible application areas, and plans for<br />

fur<strong>the</strong>r development.<br />
