My name is Adhitya Kamakshidasan and I recently graduated from Visvesvaraya National Institute of Technology, Nagpur, India. I will be working on the Google Summer of Code 2016 project “Terrain Model Generation and Analysis” under the able guidance of Professor Dr. Benno Schmidt (Hochschule Bochum) and Christian Danowski (52°North).more >
SPARQL endpoint and interoperability of the enviroCar Linked Data – Final Blog Post
Introduction
With only a few days left, the enviroCar SPARQL endpoint comes closer than ever to becoming reality. Much work and research has been put into an immensely important segment of the 52°North enviroCar project – the data. This project involves all kinds of data from standard relational to semi-structured to geo-spatial, which makes it both versatile and extendible. In a nutshell, we extract enviroCar’s data from its database form, convert it to the Linked Data format, store it in a triple store and serve it to the world as an Endpoint. Have a look at how different data looks when represented in different formats!more >
3D Connection Maps
Introduction
The Google Summer of Code for the year 2015, is over! And that was fast!
With the help of my August mentors, Benno Schmidt and Christian Danowski, I’ve been able to make some good progress towards building the WorldViz connection map module. This blog post is a continuation of my previous blog post which can be found here.
SPARQL endpoint and Interoperability of enviroCar data : Midterm Report
Introduction
The enviroCar SPARQL endpoint is a feature that enables the enviroCar data to be queried in RDF. This feature creates an open endpoint for crawlers and other bots and allows them to crawl the data and let the data be part of the LOD cloud. With the enviroCar server’s current architecture, it is possible to query the data by converting the entities on the fly into RDF when a particular kind of request is made. Please find a more detailed description about the project’s evolution on the SPARQL EndPoint wiki page.
Over the past few weeks, I’ve embarked on the task of moving the data from mongoDB (the database of choice for the enviroCar server) and cloning the entire database content to a raw data type, independent of database formats. My task also involved solving the problem of trying to remove the tight coupling of frameworks with the generation and retrieval of data. This would make more data interchanging processes more commonly known as ETL processes. This is a design for future implementation and can be found here.
