Computer Projects of Illinois (CPI) successfully delivered an OpenFox Message Switch upgrade designed to help the West Virginia State Police prepare for Nlets’ transition from legacy, dot-delimited messages to NIEM XML data exchanges.
CPI began by reviewing transaction histories and validating current message formats against Nlets compliance and monthly statistics reports. This analysis identified the in-scope message keys and ensured that the solution aligned with Nlets’ available XML standards.
The OpenFox platform then enabled XML-capable processing for Nlets traffic without requiring changes to the State Police’s existing source systems or end-user inquiry formats. Incoming Nlets XML queries were converted into the inquiry formats already used by West Virginia’s repositories, allowing existing systems to continue operating normally.
For outbound traffic, OpenFox converted qualifying legacy-format inquiries into fully tagged, standardized XML for transmission to Nlets. The system also handled responses appropriately: already standardized XML payloads were forwarded without alteration, while text and non-standard XML responses were safely encapsulated in NIEM XML without changing their original content.
To improve usability for in-state users, CPI applied standard Nlets presentation stylesheets, transforming XML responses back into readable text before delivery to existing client systems. CPI also conducted systems integration testing across outbound queries, inbound responses, administrative messages, inbound Nlets inquiries, and outbound repository responses.
Together, these capabilities delivered a controlled, standards-based path toward Nlets XML readiness. The solution preserved established operations, supported reliable message exchange, and positioned the West Virginia State Police closer to compliance with Nlets’ retirement of legacy message formats.
CPI OpenFox delivered a successful SWQ enhancement that enabled the West Virginia State Police to exchange state warrant transactions with Nlets in NIEM format.
Modernized Warrant-Query Solution
Computer Projects of Illinois (CPI) completed the SWQ Enhancements project for the West Virginia State Police by configuring its OpenFox Message Switch to support modern, standards-based warrant communications. The solution enabled State Warrant Query (SWQ) messages to route to the agency’s DMV web service in National Information Exchange Model (NIEM) format.
CPI also configured State Warrant Response (SWR) processing so that DMV responses could be accepted and returned to the originating query sources as Wanted Person replies. The configuration used the Nlets Control field to ensure responses were properly directed through the transaction flow.
To provide a consistent user-facing result, CPI applied the standard Nlets NIEM presentation stylesheets to SWQ and SWR transactions. The project relied on the existing hardware platform, avoiding the need for additional third-party products.
CPI validated its OpenFox components through integration testing before the solution was made available for customer user acceptance testing. The West Virginia State Police then reviewed the delivered functionality to confirm that SWQ and SWR messages routed to the DMV web service in NIEM format, that SWR responses contained a conformant Nlets Control field, and that standard Nlets presentation was generated during processing.
Together, these capabilities delivered an OpenFox solution designed to support reliable, standardized warrant-query and response exchanges between the West Virginia State Police, its DMV interface, and the Nlets network.
