Coverages, JSON-LD and RDF Data Cubes

Jon D. Blower, Maik Riechert
2016 International Conference Geographic Information Science  
There is considerable current interest in helping the wider Web community use coverage data, by providing data in more general formats such as JSON and RDF, and by using commonly-accepted vocabularies.  ...  Many kinds of scientific data, including satellite imagery, climate simulations and sensor data, can be represented as coverages, which are essentially mappings from points in space and time to data values  ...  CovJSON makes use of JSON-LD [9] , a means of representing RDF data in JSON.  ...

Raul Palma, Soumya Brahma, Malgorzata Wolniewicz
2022 Zenodo  
RELIANCE is leveraging data cubes to provide earth scientists with an efficient and scalable structured data access and discovery.  ...  As described in D4.1, Data Cubes are becoming a reference service to provide a data access infrastructure and a reference set of tools for geospatial data management, mostly related to the access and exploitation  ...  According to the metadata model proposed for Data Cubes in D4.1, there is a coverage metadata layer in Data Cubes to cover these dimensions.  ...

Supporting the Linked Data Life Cycle Using an Integrated Tool Stack [chapter]

Bert Van Nuffelen, Valentina Janev, Michael Martin, Vuk Mijovic, Sebastian Tramp
2014 Lecture Notes in Computer Science  
We will show how to get access; which component covers which aspect of the Linked Data life cycle and how using the stack eases the access to Linked Data management tools.  ...  Therefore the creation, management, curation and publication of Linked Data are critical aspects for an application's success. For all of these aspects the LOD2 project provides components.  ...  The RDF Data Cube Validation Tool aims at speeding-up the processing and publishing of Linked Data in RDF Data Cube format.  ...

D5.1 RO Model Adapted to EOSC

Oscar Corcho, Esteban González, Daniel Garijo, Raul Palma
2021 Zenodo  
One of the key characteristics of the proposed RO specification is that it is data-cube centric, as a fundamental differentiating principle of the Earth Science communities that are supported by RELIANCE  ...  Finally, RELIANCE-RO will be the basis for the implementation of the RELIANCE RO repository (ROHub), and hence compatibility is also looked for during its implementation.  ...  The main difference of this specification with respect to the previous ones is that it uses, by default, JSON-LD (a web developer-friendly serialization of RDF) and extends schema.org (a popular markup  ...

New Model for Geospatial Coverages in JSON [chapter]

Joan Maso, Alaitz Zabala Torres, Peter Baumann
2019 Exploring the Convergence of Big Data and the Internet of Things  
The combination of a coverage implementation schema in JSON, binary arrays, and HTML5 canvas makes it possible that web map browsers can be directly implemented in JavaScript.  ...  The standard used to describe and distribute coverages is called web coverage service (WCS).  ...  Context documents that are used in CIS instances to describe the JSON files in a way that a JSON-LD engine can automatically transform the JSON CIS documents to a RDF encoding.  ...

Efficient Analytical Queries on Semantic Web Data Cubes [article]

Lorena Etcheverry, Alejandro A. Vaisman
2017 arXiv   pre-print
Once data cubes are represented on the SW, we need tools to analyze them. However, writing efficient analytical queries over SW cubes demands a deep knowledge of RDF and SPARQL.  ...  Multidimensional data are typically represented as data cubes, and exploited using Online Analytical Processing (OLAP) techniques.  ...  Regarding the first challenge, the RDF Data Cube Vocabulary [1] (QB) is the current W3C standard to represent statistical data following LD principles.  ...
