Linked Data is about enabling computers to search structured information about “things” over the web. The linking methodology is based on the following Semantic Web principles:
1) Things are uniquely identified using Uniform Resource Identifiers (URIs).
2) Use HTTP (HyperText Transfer Protocol) URIs, to make those things accessible by computer programs.
3) The knowledge of things is expressed using the W3C Resource Description Framework (RDF) and queried via SPARQL.
For the sixth Interoperability Day organized by the French forum of the Open Geospatial Consortium (OGC) in 2012, the Lyon metropolis created a first sample of CityGML data in order to test its integration within different market tools. The program of this experiment is described at: http://www.forumogcfrance.org/journee-interoperabilite/archives-2012/programme-77/

Earlier this month, Steve Liang, chair of the OGC SensorThings Standards Working Group (SWG) received an email from someone planning to implement the candidate SensorThings API on top of the OpenIoT platform. She wanted to get answers to these questions about SensorThings before coding:
Back in 2000, the OGC Members determined that the W3C XLink recommendation was well suited to the requirements for GML 2.0 as well as other OGC standards. However, at that time, W3C did not have a XLink schema. Therefore, the OGC Members decided to define an OGC XLink schema that was based on the W3C XLink recommendation. This XLink schema is now used in numerous OGC standards (See below).
Geospatial Data has always been Big Data. Now Big Data Analytics for geospatial data is available to allow users to analyze massive volumes of geospatial data. Petabyte archives for remotely sensed geodata were being planned in the 1980s, and growth has met expectations. Add to this the ever increasing volume and reliability of real time sensor observations, the need for high performance, big data analytics for modeling and simulation of geospatially enabled content is greater than ever. In the
It was a great personal pleasure for me to attend the the 98th OGC Technical Committee Meeting earlier this month at the World Bank in Washington, DC. The venue, attendees and scope of important work made me immensely proud of the organization that I have served for more than 21 years.
The OGC is participating this week in ATIEC, the 2012 Air Transportation Information Exchange Conference. The conference is focused on achieving global harmonization through collaboration. It runs from Aug 28 to Aug 30, 2012.
