3 Navy SPAWR Dahlgren’s Net-Centric Adapter for Legacy Systems (NCALS) Net-Centric Adapter for Legacy Systems –Thomas, A.; Turner, T.; Soderlund, S. –Systems Journal, IEEE –Volume 3, Issue 3, Sept Page(s): –Digital Object Identifier /JSYST –Summary:The Net-Centric Adapter for Legacy Systems (NCALS) is a software technology that makes legacy system data and services available in near real- time to the military Global Information Grid (GIG). The intent of NCALS is to lower the cost and risk, and to decrease the time required for legacy systems to comply with U.S. Department of Defense (DoD) net-centric technical standards. Many different systems could use a common, configurable NCALS software component to comply with these standards. The benefit to the warfighter is improved interoperability with joint and coalition forces. NCALS enables legacy systems to move to a Service-Oriented Architecture (SOA) compatible with the GIG without requiring a costly and risky re-architecture of their legacy software. In addition, NCALS enables mission critical systems such as weapon systems to segregate their real-time, mission critical software from enterprise integration software. This maintains the safety and security required by such systems, while accommodating rapid changes in Internet-based, enterprise technologies. This paper will discuss the legacy system challenge and describe a technology prototype developed by the Naval Surface Warfare Center (NSWC) Dahlgren to realize the NCALS concept. The prototype works automatically, behind the scenes, to expose legacy data to the GIG and to make GIG data available to legacy systems.

4 Put Your Desktop in the Cloud to Support the Open Government Directive and Data.gov/semantic Imagine that your desktop worked like your mobile device (e.g. iPhone): –All your files and functions were in the network cloud or downloaded to the device / desktop. Issued that challenge to the Washington Semantic Web Meetup earlier this week: –Partly Cloudy With a Chance of Semantics See

5 Recent Development The Object Management Group issued a request for proposals to provide better connectivity between models and modeling languages defined in OMG and RDF Linked Open Data: –Title: MOF to RDF Structural Mapping in support of Linked Open Data RDF and Linked Open Data (LOD) have become important technologies for exposing, managing, analyzing, linking and federating data and metadata. This set of RDF based technologies, sometimes known as the “Semantic Web” or “Web 3.0”, are emerging as the lingua franca of data on the web. Major initiatives such as the President’s open government initiative are moving to the use of RDF & Linked Open Data as the foundation for publishing all government data and metadata in support of transparency. OMG & MOF based models should be a part of the LOD and Web 3.0 data cloud. The objective of this RFP is to define a structural mapping between OMG- MOF models and RDF to provide for better integration of MDA and LOD, to enable the ability to apply LOD capabilities to MOF compliant models and to make the information available in MOF compliant models available as LOD web resources. Any MOF based model should be able to become a LOD resource.

6 Recent Development The Object Management Group issued a request for proposals to provide better connectivity between models and modeling languages defined in OMG and RDF Linked Open Data: –Title: MOF to RDF Structural Mapping in support of Linked Open Data (continued) The model/LOD connection is also very good news for the Open Government Initiative which calls for government to be more open, visible, collaborative and participatory. Government architectures are the primary source of structured information about government processes, services, rules and data. As such the data contained in these models, which will become visible as Linked Open Data, will further the open government initiative. ModelDriven.org has done a preliminary open source implementation of this mapping as part of the Enterprise Knowledge Base (EKB) project ( ). Those interested in participating in the standards and/or open source efforts are welcome to contact us for more information on how to engage.
