Tying it all together: Inter-operable Topic-Centred Information Portals

In order to be more flexible in publishing information and improve accessibility of information for end-users, Oslo Municipality has funded the SUBLIMA project [25]. Within this project a stack of open source Semantic Web and Content Management System (CMS) components is used in order to deliver a flexible solution for publication of meta-data from libraries. Queries from a specific front-end are automatically dispatched to the available SPARQL end-points [23] in a pool of library and archive based installations. Returning results are presented to the user in an integral manner. The final delivery consists of an open source software stack based on Semantic Web Technology and W3C standards. Finally resulting in a well-defined and approved stack of software, major efforts has been spent on licensing issues, immaturity of component parts, ill-defined documentation of software and conversion of older bases into OWL [5]. Experiences and problems have been discussed with and reported into the respective communities.
