Computerworld - The Florida Department of Law Enforcement this month will begin a $15 million, yearlong effort to integrate the back-end systems of 500 law enforcement agencies across the state so they can share data.
The first phase of the Florida Law Enforcement Exchange (FLEX) project is to inventory data housed in the records management systems of the various agencies and create a metadata management layer for the new data exchange system, according to state officials.
Workers in the state's law enforcement offices must now use the phone or e-mail to find out if an agency in a different part of the state has any information related to cases under investigation. With FLEX, users will be able to access statewide law enforcement data with a single query, said Brenda Owens, the state's CIO.
"Our goal is to provide seamless access to data across the state," Owens said. "An operator sitting at a PC in a police department doesn't know or care what the data looks like; they can put the inquiry in and get the information back. You have to have a common language, a common understanding of what is out there before you start sharing."
In large integration projects such as FLEX, simply getting various organizations to agree on what metadata to use often can derail or substantially delay efforts to link systems. In Florida, individual agencies have worked together to share data as part of eight regional groups.
However, these regional groups did not want to be forced to log out of their native records management applications and log into a new application to do statewide queries, according to Mike Phillips, technical coordinator for the FLEX project. To provide data translation, FLEX will use a data sharing standard developed by the U.S. Department of Justice called the Federal Global Justice XML Data Model.
While the decision to use the Justice Department's XML model to do data translation means each region can continue to use its own applications as part of FLEX, law enforcement officials still needed to find a way to extract existing data definitions from each region and to create a common vocabulary for statewide data exchanges, Phillips said.
Most of the regions have been manually mapping the metadata needed to exchange information with other regional agencies, a method that would not allow FLEX to be completed by its March 2007 deadline. To speed up the integration process, the state will use Dublin, Ohio-based Sypherlink Inc.'s Harvester metadata discovery and mapping tool to map data from the disparate systems
