求翻译：n ProtoGENI the resource specification is divided into three closely-related languages to address the purposes of advertising, request, and experiment manifest. The cOntrol, Management and Measurement Framework (OMF) originally developed for controlling and instrumenting Orbit testbed introduces a Domain-specific Language named OEDL. OEDL is based on the Ruby scripting language, and utilizes Ruby’s meta-programming capabilities to provide experiment specific commands and statements. The Open Resource Control Architecture (ORCA) control framework uses ontologies to build semantic optical network models as a basis of the resource description. ORCA and BEN team develop the NDL-OWL on tology---an extension of the Network Description Language (NDL) using Web Ontology Language (OWL). NDL-OWL ontology reuses the core concepts in NDL, applies various substrate-specific capabilities and constraints to resource sharing and stitching within the ORCA control framework. The resulting NDL-OWL graph is processed by resource control modules, and dedicated to individual ORCA actors for generating a feasible schedule of configuration actions that instantiate the embedding in network.是什么意思？
