Disclosed is a method, system, and computer program product for preserving actions taken after a snapshot. One embodiment of the method may comprise capturing a snapshot of a virtualized container environment (VCE), the VCE comprising one or more applications-of-interest. The method may further comprise intercepting an event-of-interest directed to an application-of-interest within the VCE. The method may further comprise automatically storing the intercepted event in an action database. The method may further comprise, in response to a user instruction to revert the VCE to a prior snapshot, generating an automated script from the intercepted events, wherein the automated script comprises actions that occurred in the VCE after capture of the selected snapshot; and executing the automated script.

Preserving changes when reverting back to a snapshot

A system modeling meta-model language model for a system is extracted from a natural language specification of the system. Syntactic structure is extracted from the specification of a system. The syntactic structure represents a set of at least one syntactic subject. A first mapping is created between a predetermined set of the at least one syntactic subject and respective meta-model elements for a system modeling meta-model language. At least one of the meta-model elements is constructed in accordance with the mapping for each identified syntactic subject. The created meta-model structural elements are created for conversion into a model of the system.
