"Information sharing is the defining principle for public safety and Web Services is the technology best positioned to facilitate sharing and lower costs. The National Law Enforcement Telecommunication System (NLETS) provides a network for criminal justice information exchange throughout North America. NLETS is defining new standards based upon XML and Web Services under the Accelerated Information Sharing for Law Enforcement (AISLE) Project. AISLE deployed an XML Message Router (XMR) which provides operational Web Services capabilities. The AISLE Project developed and published detailed specifications based upon a broader Justice XML Data Dictionary. Initial Web Services provided partner agencies with guaranteed message services functionality and interoperability with existing systems by providing bi-directional legacy transaction transformation capabilities. AISLE uses a self-defining XML transaction with Web Services Attachments to support legacy image transfer. Future efforts will focus on more distributed Web Services as well as Web Services Security."
