13 November 2013 – The Open Geospatial Consortium (OGC®) is seekingcomments on the candidate standard, “OGC® OpenSearch Geo and TimeExtensions”. This document extends the implementation of the popularOpenSearch technologies so that users can take advantage of the geospatialsearch capabilities enabled by OGC standards.
Different types of content require different types of search engines. OpenSearch(http://www.opensearch.org) providesa standard way of describing search engine capabilities so that they can beleveraged by search client applications like modern Web browsers. The OGC® OpenSearch Geo and TimeExtensions candidate standard provides a very simple way to configure OpenSearch forspatial and temporal queries over distributed repositories of contents havinggeographic and time properties, and for syndication of these search results inone large index.
Digital resources are becoming more complex and diverse, and this is especiallytrue with respect to sensor data and Web connected sensors. Such data isincreasingly becoming discoverable and usable through open interfaces thatimplement OGC standards (http://www.opengeospatial.org/standards),but most of this data remains undiscoverable via popular search engines. The OGC OpenSearch Geo and TimeExtensions candidate standard specifies how to enhance search engines andconfigure them to access sensor data servers, so that users can query resourceURLs through search combinations of time extents, geographic areas or locationnames, and likely keywords.
The OGC® OpenSearch Geo and Time Extensions draft standard includeswork undertaken within the GENESI-DR (Ground European Network for Earth ScienceInteroperations – Digital Repositories) project funded by the 7th Frameworkprogram of the European (EC Grant Agreement no. 212073) and the follow-upproject GENESI-DEC (Ground European Network for Earth Science Interoperations -Digital Earth Community) funded by the same program (Contract nº RI-261623).The document was further supported by the ESA HMA (Heterogeneous MissionsAccessibility) initiative and related projects.

All OGC standards are free and publicly available.
The OGC is an international consortium of more than 475 companies,government agencies, research organizations, and universities participating ina consensus process to develop publicly available geospatial standards. OGCStandards support interoperable solutions that “geo-enable” the Web,wireless and location-based services, and mainstream IT. OGC Standards empowertechnology developers to make geospatial information and services accessibleand useful with any application that needs to be geospatially enabled.
