Flexible Range Semantic Annotations Based on RDFa

In this paper, a new flexible range markup technique for Web documents is presented as an alternative to XPointer technology, based on the RDFa standard. The principal objective is to define semantic annotations that support the evolution of annotated Web documents more effectively than XPointer. The term ‘Flexible Range' indicates that annotations can be defined over different ranges of text within a Web page and multimedia objects within it, independently of its HTML tags.
