“…[5] gives a model for temporal RDF, allowing triples to be specified as true for a finite time interval. [12] defines a model for representing multi-dimensional RDF, where information can be context dependent; for instance the title of a book may be represented in different languages. Our approach differs from all of the above: (i) we define a general framework for extending the RDF data model with annotations from an arbitrary partially ordered set; (ii) we give efficient algorithms for querying annotated RDF ontologies.…”

There are numerous extensions of RDF that support temporal reasoning, reasoning about pedigree, reasoning about uncertainty, and so on. In this paper, we present Annotated RDF (or aRDF for short) in which RDF triples are annotated by members of a partially ordered set (with bottom element) that can be selected in any way desired by the user. We present a formal declarative semantics (model theory) for annotated RDF and develop algorithms to check consistency of aRDF theories and to answer queries to aRDF theories. We show that annotated RDF captures versions of all the forms of reasoning mentioned above within a single unified framework. We develop a prototype aRDF implementation and show that our algorithms work very fast indeed -in fact, in just a matter of seconds for theories with over 100,000 nodes.

“…18 The issue appears to have been ongoing for many years as Gergatsoulis and Lilis maintain that the web lacks semantic information and it has proved challenging to process such a massive set of interconnected data as mentioned 18 years ago. 19 Clearly, online collections must be understood and used efficiently both by humans and machines, because machine-consumable content will end up in human-consumable content. 20…”

This article focuses on the problematic democratization of small museum collections online in Cyprus. While the web has enabled cultural heritage organizations to democratize information to diverse audiences, numerous small museums do not enjoy the fruits of this digital revolution; many of them cannot democratize their collections online. The current literature provides insight into small and large museums’ challenges worldwide. However, we do not have any knowledge concerning small Cypriot museums. This article aims to fulfill this gap by raising the following research question: What is the current state of small museum collections online in Cyprus, and what challenges do they face in democratizing their collections online? We present our empirical results from the interview summaries gathered from six small museums.

“…Within the database community, extensive research has been conducted on two notions of time: valid time (when a change occurred in the real world) and transaction time (when a change was entered to the database) [22]. Various proposals adapting the notion of valid time have been made by the Linked Data community, such as temporal RDF graphs (temporal reification vocabulary) [16,15], multidimensional RDF (extended triple notion) [10], applied temporal RDF (named graphs) [43], stRDF (temporal quad) [25], RDF SpatialTemporalThematic (based on temporal graphs) [34], and temporal quintuples [26].…”

Abstract. Most datasets on the Linked Data Web impose a static view on the represented entities and relations between them, neglecting temporal aspects of the reality they represent. In this paper, we address the representation of resources in their spatial, temporal and thematic context. We review the controversial proposals for the representation of time-dependent relations on the Linked Data Web. We argue that representing and using such relations is made hard through the direct encoding of inadequate conceptualizations, rather than through inherent limitations of the representation language RDF. Using the example of researcher life lines extracted from curricula vitae, we show how to model sequences of activities in terms of events. We build upon the event participation pattern from the DOLCE Ultralite+DnS Ontology and show how places and social roles that people play during their careers relate to events. Furthermore, we demonstrate how scientific achievements can be related to events in a career trajectory by means of temporal reasoning.
