This paper describes how a platform for publishing and querying linked open data for the Brussels Capital region in Belgium is built. Data are provided as relational tables or XML documents and are mapped into the RDF data model using R2RML, a standard language that allows defining customized mappings from relational databases to RDF datasets. In this work, data are spatiotemporal in nature; therefore, R2RML must be adapted to allow producing spatiotemporal Linked Open Data.Data generated in this way are used to populate a SPARQL endpoint, where queries are submitted and the result can be displayed on a map. This endpoint is implemented using Strabon, a spatiotemporal RDF triple store built by extending the RDF store Sesame. The first part of the paper describes how R2RML is adapted to allow producing spatial RDF data and to support XML data sources. These techniques are then used to map data about cultural events and public transport in Brussels into RDF. Spatial data are stored in the form of stRDF triples, the format required by Strabon. In addition, the endpoint is enriched with external data obtained from the Linked Open Data Cloud, from sites like DBpedia, Geonames, and LinkedGeoData, to provide context for analysis. The second part of the paper shows, through a comprehensive set of the spatial extension to SPARQL (stSPARQL) queries, how the endpoint can be exploited.

<p><strong>Abstract.</strong> The Land Registry and Mapping Agency of the Netherlands (‘Kadaster’ in Dutch) is developing an online publication platform for sharing its geospatial data assets called KDP (`Kadaster Data Platform’ in Dutch). One of the main goals of this platform is to better share geospatial data with the wider, web-oriented world, including its developers, approaches, and standards. Linked Open Data (W3C), GeoSPARQL (OGC), and Open APIs (OpenAPI Specification) are the predominant standardized approaches for this purpose. As a result, the most important spatial datasets of the Netherlands – including several key registries – are now being published as Linked Open Data that can be accessed through a SPARQL endpoint and a collection of REST APIs. In addition to providing raw access to the data, Kadaster Data Platform also offers developers functionalities that allow them to gain a better understanding about the contents of its datasets. These functionalities include various ways for viewing Linked Data . This paper focuses on two of the main components the Kadaster Data Platform is using for this purpose: FacetCheck and Data Stories.</p>

Com a finalidade de representar de forma abstrata as relações e entidades, os modelos de dados ganham destaque como melhores práticas nos processos de análise e representação da informação, especificamente no planejamento e desenvolvimento de sistemas interoperáveis e persistentes. Nesse sentido, apresenta-se um estudo sobre o Europeana Data Model (EDM), modelo de dados desenvolvido pela plataforma Europeana com base nas tecnologias semânticas e nos princípios do Linked Open Data. Por meio de uma pesquisa qualitativa, exploratória, bibliográfica e documental, discute-se como o uso de um modelo de dados, tal como o EDM, possibilita que as necessidades de representação informacional de coleções de dados de patrimônios culturais sejam atendidas no ambiente Web. Desse modo, o objetivo do estudo foi analisar a estruturação e representação proposta pela Europeana para as coleções de patrimônios culturais. Como resultado, destaca-se a modelagem de dados, que é o processo pelo qual o EDM pauta seu funcionamento, possibilitando que as necessidades informacionais sejam contempladas. Conclui-se, por fim que a importância dos modelos de dados, tal como o EDM, encontra-se na possibilidade de apreender o contexto semântico a qual um conjunto de dados de patrimônios culturais pertence ou está relacionado, garantindo a persistência de seus conceitos e relações nos ambientes informacionais.

This paper describes Linked Open Data(LOD) development system and its application of medical information standard as Observational Medical Outcomes Partnership(OMOP) Common Data Model(CDM). The OMOP CDM allows for the systematic analysis of disparate observational database in each hospital. This paper describes a LOD instance development system based on SII. It can generate the application-specified instance development system automatically. Therefore, we applied by medical information standard as OMOP CDM to LOD development system. As a result, it was confirmed that there is no problem in applying to the standardization of medical information using the LOD development system.

The PHAROS consortium is adopting the Linked Art data model to make its descriptions of photo archives collections available as Linked Open Data to further support scholars in their research. Linked Art is both a community and a data model. As an international community, it works together to create a shared data model to describe art. As a data model, it is a data profile of the CIDOC Conceptual Reference Model and using Linked Open Data techniques. The goal of Linked Art is to enable museums and developers to engage in LOD initiatives more easily by providing them with shared data modelling decisions and consistent design principles.

Abstract In this paper, we propose a conceptual data model which could be the basis for future implementations of databases and digital corpuses of Ancient Egyptian texts that fully integrate the material dimensions of writing. The types of metadata that can be used for documenting the elements and relationships of this model are discussed and the resources (URIs) available for its online implementation (in the perspective of the ‘linked open data’ movement) are examined.

Abstract: The processes starting with the identification and registration of treasury properties have an essential place in the cadastral systems. Spatial data modelling studies were conducted in 2002 to establish a common standard structure on the fundamental similarities of land management systems. These studies were stated as a beginning named Core Cadastral Domain Model (CCDM), since 2006, it has been started to be made under the name of LADM. This model was accepted in 2012 as a standard model in the field of land administration by the International Organization for Standardization (ISO). In this study, an external model class is proposed for LADM’s transactions related to Treasury’s real estates properties which are related National Property Automation Project (MEOP). In order to determine the deficiency of this current external model, databases containing records related to spatial data and property rights were examined, and the deficiencies related to transactions on treasury properties were determined. The created external class is associated with the LADM’s LA_Party, LA_RRR, LA_SpatialUnit and LA_BAUnit master classes. Herewith the standardization of the external data model is ensured. If the external model is implemented by the responsible standardization of the archiving processes will be more comfortable and faster to register.

Marine spatial “open” data infrastructures (MSDI) have a significant economic and societal potential for coastal nations and their realization is driven by the evolution of the International Hydrographic Organization’s (IHO) S-100 data model for facilitating marine domain interoperability and the World Wide Web Consortium’s (W3C) best practices for spatial data publishing on the Web. The recent European directive on open data and the re-use of public sector information, known as the “Open Data Directive” is a key driver towards the establishment of “open” MSDIs among other spatial data infrastructures. The paper discusses possible data architectures for the MSDIs, examines the maturity of open data platforms that they could be built upon and compares the most prominent marine spatial data models for their applicability in relation to three marine information domains. MSDIs can facilitate the continuous data capturing of spatial-temporal physical phenomena and human activities at sea and coastal areas, the corresponding data analysis and the decision-making for achieving continual improvement in the marine planning and management processes. MSDIs could play a key role in digital government transformation (DGT) for effective data sharing and offering marine services across various stakeholders. The information provided through a MSDI can be used for safe and efficient operation of maritime traffic, exploration and exploitation of marine resources, marine spatial planning (MSP), integrated coastal zone management (ICZM), environmental protection, and naval and maritime security.
