Seismic Observations in SOS, Final Report
This is the last blog post I will be making for the Seismic SOS project!. If anyone has been keeping up with or has read my weekly reports page you will see that it has been a huge learning process for me, and I just want to say that I am very grateful to have been given this opportunity by 52°North, GSOC 2013, and the open source community.more >
OpenSensorSearch – Final blog post
The aim of the OpenSensorSearch project is to provide an implementation of a sensor discovery server with the high performance of a Solr back-end to give users results fast. In addition, we are working on harvesting mechanisms for OpenSensorSearch (OSS) to allow users and developers to write harvesters for their own sensor data sources.
In the previous blog post, we discussed the work done in the first few weeks related to the database back-end and how we used Apache Solr for indexing and fast searching. Today we present the work done in the second half of the project. It focussed on harvesting metadata from other sources and the user interface. I mainly discuss
- Javascript harvesting mechanism,
- “harvest callback” technique,
- user interface implementation with Spring MVC and
- general technical details.
