NAISC-L: A Linked Data Interlinking Framework for Libraries, Archives and Museums
(Trinity College Dublin. School of Computer Science & Statistics. Discipline of Computer Science, 2020)This thesis presents a framework for Novel Authoritative Interlinking for Semantic Web Cataloguing in Libraries - or NAISC-L (pronounced noshk-el). The Semantic Web (SW) is an extension of the current Web where data is ... -
Naked objects
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)The original concept of object-oriented software development was that the objects would be 'behaviouslly-complete' representations of the domain entities that they model. Although object oriented technologies now pervade ... -
