This article talks about Tim Berners-Lee's speech to the NSF on the Semantic Web.
Joshua Allen's take on the speech is found here.
From Joshua's site:
Tim made the point that "web services" are about performing remote operations. When viewed in high contrast, "web services" build a web of interconnected verbs, while "semantic web" builds a web of interconnected nouns. It was encouraging to see a journalist relaying the message that the two worlds will be complimentary, rather than succumb to the typical Zoroastrian storyline.
I think we could extrapolate this for our work:
"Web services" build a web of interconnected verbs, while "Learning Objects" build a web of interconnected nouns.
Web services can provide a set of actions to learning objects in the repositories.
