Conventional content management systems (CMSes) consider user management, specifically authorization to modify content objects to be orthogonal to any evolution of content within the system. This puts the burden on a system administrator or his delegates to organize an authorization scheme appropriate for the community the CMS is serving. Arguably, high quality content - especially in open access publications with little or no a priori content classification – can only be guaranteed and later sustained, if the fields of competence of authors and editors parallel the thematic aspect of the content. In this work we propose to abandon the above-mentioned line of demarcation between object authorization and object theming, and describe a framework which allows to evolve content and its ontological aspect in lockstep with content ownership.
In this work we present an architectural overview over a knowledge-based middleware based on Topic Maps. In that, we exploit the TM paradigm as much as possible trying to solve typical middleware-specific tasks. Hereby we use the concept of virtualization to homogenize the data landscape, the TM query language for semantic transformations and a dedicated, RESTful protocol for TM fragment interchange.
Both the more pragmatic Topic Map data model (TMDM) and the more fundamental Topic Map Reference Model (TMRM), have reached now a certain degree of maturity. Unfortunately, the development of these models did not occur in lockstep as they address very different needs and communities. This work tries to be the missing link by faithfully mapping TMDM instances into TMRM. For this purpose we formally introduce a refinement of the existing T model by adapting it to the latest TMRM version and by extending it to cover TMRM disclosures.
This paper presents a formalization for Topic Maps (TM). We first simplify TMRM, the current ISO standard proposal for a TM reference model and then characterize topic map instances. After defining a minimal merging operator for maps we propose a formal foundation for a TM query language. This path expression language allows us to navigate through given topic maps and to extract information. We also show how such a language can be the basis for a more industrial version of a query language and how it may serve as foundation for a constraint language to define TM-based ontologies.
