xWCPS 2.0 Language Definition

xWCPS (XPath Enabled WCPS), is a Query Language (QL) defined in the context of EarthServer Project aiming to merge two widely adopted standards, namely XPath 2.0 because of its capabilities in XML (common metadata form) handling and WCPS's raster data processing abilities, into a new construct, which enables simultaneous processing of both coverage metadata and OGC coverage content.
