“…Waktu dapat diartikan sebagai sebuah konsep yang sering digunakan dalam pernyataan linguistik dan juga merupakan topik sentral dalam filosofi yang memiliki domain-domain berbeda untuk penyampaian fisik menggunakan representasi pengetahuan dan pemikiran [6]. Hayes mengidentifikasi enam konsep waktu yang saling terkait satu sama lain.…”

ABSTRAK Waktu adalah sebuah konsep penting dalam pencatatan objek-objek warisan budaya dan peristiwa sejarah. Contoh konsep waktu yang sering digunakan dalam pencatatan objek-objek warisan budaya dan sejarah adalah waktu interval (time-interval) dan waktu titik (time-pointI. PENDAHULUAN ARISAN budaya adalah peninggalan intelektual berupa benda maupun non-benda yang menggambarkan jati diri dan kehidupan masyarakat pada masa lampau dan diwariskan dari generasi sebelumnya serta dilestarikan untuk generasi yang akan datang. Warisan budaya bisa berupa benda atau material seperti candi, monumen, arca, pisau, tombak, maupun alat-alat purbakala lain yang dapat dilihat dan dipegang. Warisan budaya juga bisa berupa non-benda seperti tradisi, kisah, sejarah tak tertulis, seni pertunjukan, ritual, pengetahuan maupun keterampilan yang ditransmisikan dari generasi ke generasi dalam suatu komunitas.Pelestarian warisan budaya bisa dilakukan dengan berbagai cara. Di bidang teknologi informasi, pelestarian warisan budaya bisa dilakukan dengan cara mendokumentasikan artifak-artifak maupun peninggalan bersejarah yang lain ke dalam bentuk digital agar dapat dimanfaatkan sebagai media pembelajaran bagi masyarakat umum. Di Indonesia saat ini, pendokumentasian warisan budaya masih terbatas pada kepentingan inventarisasi pencatatan koleksi museum saja. Apabila seseorang ingin mendapatkan informasi tentang sejarah, maka orang tersebut harus datang langsung ke museum untuk mencari tahu, karena informasi sejarah Indonesia saat ini tidak bisa atau sangat W

An Ontological Approach to Design Real-time Applications

These recent years, we have seen the emergence of several studies allowing a linkage between databases and ontologies to facilitate the design of databases. However, these studies do not address the needs of the advanced applications, because they do not integrate mechanisms that consider the temporal characteristic. In addition, the complexity of real-time applications is ever increasing which makes their design processes very difficult. For that purpose, a new vision will allow to fill in the limits of these studies and to suggest a method to conceptualize this kind of databases (real-time databases). This vision needs to define a new ontology to be integrated into these databases. This suggested ontology should be used to represent a domain in an explicit way without any ambiguity, to describe the most general categories and relations, and to define the temporal information and to resolve the semantic conflicts. In this paper, our solution is to advance an ontological modeling for real-time applications.

“…Meta-domain ontologies describe concepts such as time, space, privacy that can't be related to either the physical or the cyber worlds because of their nature. As already noted by Petnga and Austin (2013), model-based systems engineering procedures for CPS depend critically on models of time and formal representations for temporal semantics. The second part of this framework is the domain-specific rules (laws and theories) that accompany each of the domain-specific ontologies.…”

“…Given that every year, hundreds of lives are lost at stop light intersections in the United States, the importance of this problem cannot be overstated (Hurwitz 2013). We have recently shown (Petnga and Austin, 2013) that looking at this problem from a CPS perspective brings new perspective on its resolution. This system is an "ideal CPS" in the sense that vehicles (physical system) interact with the light (cyber system) with the aim of maximizing traffic throughput while ensuring safe crossings at the intersection.…”

“…We use a simplified version of the OWL-Time ontology (W3C 2006) that is consistent with Allen's temporal interval calculus. As indicated in Petnga and Austin (2013), interval-based models of time like this one have been found more appropriate for formal analysis having time-dependent behavior than point-based models. The excerpt below shows a definition of the #ProperTimeInterval class in XML format.…”

Abstract. This paper describes the development of semantic platforms to support the modeling, architectural design, realization, and operation of cyber-physical systems. Platform architectures work directly with formal models of domain knowledge (not just raw data) that are determinate, provable (ambiguity free), executable, and with semantic parameters and rule engines that reason with physical quantities and across domains. These concepts are exercised in a case study application: the "decision-dilemma problem" for traffic systems.
