    "abstract": "A beam physics model server (Art++) has been developed for the Jefferson Lab\naccelerator. This online model server is a redesign of the ARTEMIS model\nserver. The need arose from an impedance mismatch between the current\nrequirements and ARTEMIS capabilities. The purpose of the model server is to\ngrant access to both static (machine lattice parameters) and dynamic (actual\nmachine settings) data using a single programming interface. A set of useful\noptics calculations (R-matrix, orbit fit, etc.) has also been implemented and\ncan be invoked by clients via the model interface. Clients may also register\ntheir own dynamic models in the server. The server interacts with clients using\nthe CDEV protocol and data integrity is guaranteed by a relational database\n(Oracle8i) accessed through a persistence layer. By providing a centralized\nrepository for both data and optics calculations, the following benefits were\nachieved: optimal use of network consumption, software reuse, and ease of\nmaintenance.",
