One of the major barriers to the deployment of Linked Data is the difficulty that data publishers have in determining which vocabularies to use to describe the semantics of data. This systematic report describes Linked Open Vocabularies (LOV), a high-quality catalogue of reusable vocabularies for the description of data on the Web. The LOV initiative(More)
As many cities around the world provide access to raw public data along the Open Data movement, many questions arise concerning the accessibility of these data. Various data formats, duplicate identifiers, heterogeneous metadata schema descriptions, and diverse means to access or query the data exist. These factors make it difficult for consumers to reuse(More)
Both topic maps specifications and literature have implicitly or explicitly presented the standard as 'ontology-agnostic', meaning they are able to support, represent and manage any kind of knowledge in any kind of ontological context, and even independently of the constraints imposed by any ontology. Topic maps are able to express 'anything about anything(More)
The uptake of Linked Data (LD) has promoted the proliferation of datasets and their associated ontologies bringing their semantic to the data being published. These ontologies should be evaluated at different stages, both during their development and their publication. As important as correctly modelling the intended part of the world to be captured in an(More)
Vocabularies are more and more (re)-used in the Linked Data ecosystem. However, managing the prefixes associated to their Uniform Resource Identifiers (URIs) is still cumbersome and namespaces are sometimes referring to different pair <prefix, URI>. In this paper, we propose to align two well-known services with the aim of managing and harmonizing(More)
Exchanging information about a subject with semantic tools, and singularly topic maps, demands both human and computer readable ways of agreement about this subject identity. Since subjects are always addressed through representations, hence agreement about subject identity must be grounded on some sort of representation, be it a name, an addressable(More)
