  abstract = {Creation of rich, ontology-based metadata is one of the major challenges in 
developing the Semantic Web. Emerging applications utilizing semantic web techniques, such as 
semantic portals, cannot be realized if there are no proper tools to provide metadata for them. 
This paper discusses how to make provision of metadata easier and cost-effective by an 
annotation framework comprising of annotation editor combined with shared ontology services. We 
have developed an annotation system supporting distributed collaboration in creating 
annotations, and hiding the complexity of the annotation schema and the domain ontologies from 
the annotators. Our system adapts flexibly to different metadata schemas, which makes it 
suitable for different applications. Support for using ontologies is based on ontology services, 
such as concept searching and browsing, concept URI fetching, semantic autocompletion and 
linguistic concept extraction. The system is being tested in various practical semantic portal 
projects. }
