 > What are some services that SemWeb > applications could expose for discovery > and integration into web client applications I am still hopeful that annotation services for web browsing can become popular. I think that generic annotation (including rating services, passive/implicit rating, bookmark integration) is a killer app, and has failed so far only because implementations are walled gardens. > including mobile applications? In other I expect eventually to see location-based services provided using semantic web technologies. People want to share information "about" locations with other people. I've seen at least one system based on RDF which lets people register using a cellphone, and then when they are at a particular venue, "hook up" with other people nearby. I would imagine things like venue reviews, tour-guide style information, and so on would be useful to store semantically. The reason I expect semweb technologies to eventually win here is because there is strong incentive to have a standard an open mechanism for submitting and querying location-based information. Current location-based services are walled gardens; for example, a restaurant owner cannot submit information about her own restaurant without going through a proprietary, vendor-owned network. Different services have different data. The data "belongs" to the network rather than the location, and there is strong incentive from people invested in the location to reverse this. So off the top of my head, I think the two most "realistic" scenarios are annotation services and location-based services. I have many other fantastical scenarios in mind. Cars could passively collect and share metadata about road conditions, aggressive drivers, and so on. Humans could attach memories to inanimate objects tagged by RFID. (Also note I am just assuming SOA/WS are simply service delivery mechanism that could be used to deliver a semantic web service, so in my mind the two are mostly orthogonal/complimentary)
