Extensible Markup Language (XML) is a new trend in the Geographical Information System. XML has a long history in terms of providing a reliable data management strategy. It was designed to take benefit of Standard Generalized Markup Language (SGML) by removing the complicated definition parts, and focuses on how the data should be describe in a simpler manner. In GIS, XML were used in fulfilling different organization needs in terms of data sharing, data definition, transportation and others. The Open Location Services (OpenLS), a standard introduced by Open Geospatial Consortium uses the efficiency of XML throughout its specification. The Abstract Data Type (ADT) of OpenLS were defined as application schemas encoded in XML for Location Services (XLS). XML were also used in Mobile Location Protocol (MLP) for transmitting location information from the Mobile Positioning Center . As the needs of integration and interoperability among different systems arise, an alternative for storing and retrieving spatial data for Location Based Services should be considered. This paper describes the best strategy to implement XML database as a storage option for spatial data, based on OpenLS specification. It will also discuss the possibilities of serving the data in a Web Services platform, another technology based on XML.
