Various applications will have to be developed, including a search engine database for all the items, and someone will have to develop a standard for it. It might be eBay, it might be Microsoft, it might be Google. But eventually we will see marketplaces based on RDF. Publishing information about things on the Internet will be much easier than before. One day we will be able to collect information about almost everything on the web in a standardized RDF format. publishing of data or the request of a machine for such data. Is it all too difficult then? Where Semantic Web technologies have found a greater degree of practical adoption, it has tended to be among core specialized communities and organizations for intra-company projects. The practical constraints toward adoption appear less challenging where domain and scope is more limited than that of the general public and the World-Wide Web. dissemination of information is well developed. At this stage, most of the organizations represented within the IASA do not really feel they need the Semantic Web. So at the current stage of development, the Semantic Web is not a priority for the IASA. But this does not mean it will be ignored. A very soft, although practical introduction to some of the beauties of the Semantic Web might be offered by companies such as NOA-Audio, which have systems that are particularly adaptable to a Semantic Web extension, and which have representatives on IASA technical committees. Media archiving could be an ideal application. However, the IASA (International Association of Sound The advantages that the Semantic and Audiovisual Archives) is not yet Web brings in terms of reuse, The commercial potential of media committed to the Semantic Web. dynamism, fl exibility, and openness archives which are searchable Documentation practices in libraries also pose the possibility of through Semantic Web technology and archives are well established. ineffi ciencies such as complexity, and could be the argument that spurs performance degradation.
