Application	ISO 19143 describes XML and Key-Value Pairs (KVP) encodings of a system-neutral syntax for expressing projections, selections and sorting clauses, collectively called a query expression.
Conformance classes	Query Ad-hoc Query Functions Resource Identification Minimum Standard Filter Standard Filter Minimum Spatial Filter Spatial Filter Minimum Temporal Filter Temporal Filter Version navigation Sorting Extended Operators Minimum XPath Schema Element Function
Implementation benefits	Filter Encoding (FE) describes XML and KVP encodings for expressing filters for spatial queries to select a subset of features based on specific attributes. FE is used in conjunction with other standards and thus allows a client to, for example, create a map using a WMS that only shows residential areas.
Products	FE is implemented in conjunction with other services, such as WMS or WFS. An open source examples of an implementation of FE is OpenGeo Suite 4.1.1.
