Summary form only given. With the arrival of the new computing paradigm in addressing autonomous systems for heterogeneous distributed architectures, distributed component technologies face challenges ahead. One of the key issues is how one can have component models adapt and respond to environment changes autonomously. We argue that additional annotation specifications for components are needed to advance this process. We first present additional annotation specifications for components. This information can then be retrieved by Java introspection and represented in DAML+OIL language, which is based on the RDF schema and the XML syntax. Based on the specifications, we then present a component management service (CMS) model and architecture to address the specification and composition issues of components on heterogeneous distributed architectures. Experimental results show significant performance improvements with our support of component adaptations in all cases. Our work presents a major advance for areas related to specifications and compositions of distributed components.
