U.S. Navy researchers have developed a computer-based method for identifying internet web pages containing specific pre-set information. The patented technology is available via license agreement to companies that would make, use, or sell it commercially.
Worldwide governmental and commercial entities continue to make more geospatial data available on the internet. The Open Geospatial Consortium (OGC) provides public specifications for a variety of geospatial web services such as Web Mapping Services, Web Feature Services, and Web Coverage Services. Web Mapping Services (WMS) are those services that interface client applications with server applications to provide a map image.
The OGC has provided several public standards for geospatial web services, which have grown substantially in popularity and use over the past years. However, while some client and server applications adhere to the OGC standards, the process for searching for OGC web services on the internet is still mostly done manually, making the process tedious and slow. There is a need for automating the method to save time.
A team of Navy researchers has developed a computer-based method for identifying internet web pages containing documents that comply with a predetermined XML schema. The method includes searching the internet using initial search terms and identifying a first set of HTTP URLs, followed by web crawling this first set of HTTP URLs to identify additional HTTP URLs and appending a query to the identified URLs. The system then evaluates the responses to the query to determine compliance with the predetermined XML schema and stores the matching HTTP URL responses in a database. The system was developed for predetermined XML schema published by the OGC but is not limited to those.
- The selected URLs can be music files, images files, and executable files.
- The system can compare a newly discovered document against previously known WMS server documents to avoid duplication
- The system web crawls the database periodically to discover non-operational links
- Businesses can commercialize the technology by licensing U.S. Patents 7,685,133 and 8,024,318 from the Navy
