| Definitionskos:definition | This Open Geospatial Consortium (OGC) document provides an analysis of the prototype implementations, approaches and performance aspects of data size reduction and compression techniques explored in OGC Testbed 12. Specifically, it describes work done during Testbed 12 investigating compression for geospatial data sets on OGC Web Feature Service (WFS) using W3C Efficient XML Interchange (EXI) Format 1.0 (Second Edition). The investigation focused on extending WFS with EXI output formats, and the associated performance aspects of data size reduction and compression techniques. EXI is a compact representation for the Extensible Markup Language (XML) Information Set. EXI is intended to simultaneously optimize performance and the utilization of computational resources. From a practical viewpoint, EXI is designed to reduce the size of XML data exchanged between computer systems. EXI uses a grammar-driven approach designed to achieve efficient encodings using an encoding algorithm and a small set of datatype representations. Consequently, EXI processors are described by the W3C as ‘relatively simple’ and ‘can be implemented on devices with limited capacity.’ An EXI processor is used by application programs to encode their structured data into EXI streams and/or to decode EXI to make the structured data accessible. |
