The Contextually-Partitioned Web : An Investigation into the Role and Use of Structured Collabularies in Digital Repositories as Information Filters to Improve the Web User ’ s Experience

This manuscript introduces the Contextually-Partitioned Web (CPW), a theoretical digital repository model for closed environments such as classrooms, schools, or districts. In this model, subject matter experts (teachers) use a standardized schema and controlled vocabulary to identify and tag repository objects (data and resources) using RDFa and standard metadata language such as Dublin Core. Student repository users may use basic language to extend expert tagging. Tag clouds act as visual cues to the content requester (student) to guide the students in their search for information. RDFa provides object permanence and extends resource discovery beyond tagged elements. For the purposes of this paper, the terms repository and library will be used interchangeably.
