Abstract

The history of controlled vocabularies in libraries has long carried the promise of improved retrieval systems based on common goals and shared efforts. This is especially true of subject vocabularies whose data have been managed at two levels. Firstly, in management systems of their own, from which vocabulary products are derived, as in the case of the most commonly used subject heading languages, thesauri and classification schemes. Secondly, in the so called library authority files, that may apply such vocabularies or be used to develop local ones, to control subject access to a given library or bibliographic collection. This two-levelled model of building and sharing subject vocabularies' data is about to change. For many decades the concept of 'intellectual sharing' has been prevalent in such activities, underpinning re-use by adoption and/or collaboration in the management of shared subject systems. Although the Internet has enabled the exposure of centrally managed subject systems and library authority files it has done little to alleviate the significant efforts needed for a full deployment of network shared vocabularies. In particular, the use of classification systems did not advance much. While in theory their potential for subject interoperability across domains and languages is recognized, classifications remain poorly used in practice. They still lack intelligent means to effectively connect and communicate data throughout the network, in a synchronic and non-redundant way. More recently, the development of web technologies has leveraged the concepts of connection, communication and sharing of data to a new level, through linked data. What changes will this bring to the architecture of library subject authority data? Will classification systems live to see the age of their full and easy deployment?
