X-15's proprietary Configuration Specification Language (CSL) enables secure collaboration and management of engineering compliance throughout the asset life cycle. The company aims to unlock the true value of the digital thread by closing the loop between the physical and virtual worlds of a company's products. To achieve this, X-15 is developing Aries, the industry's first pure-SaaS, real-time "as-a-service" configuration compliance engine delivered entirely through an API. Aries standardizes BOMs, maintenance policies, and configuration rules/directives using X-15's human/machine readable CSL.
