11. A computer system for assigning a direction of impact to an association between assets based on an impact of an event mapped to at least one of the assets comprising a computer comprising at least one processor, one or more memories, one or more computer readable storage media having program instructions executable by the computer to perform the program instructions comprising: creating, by the computer, a first topic map meta-model that identifies assets and events in a topic map based index with instance ontology based on a topic map meta model that identifies assets and a topic map meta-model that identifies events, mapping assets to events through at least one association between at least one asset of the topic map meta-model that identifies assets and at least one event of the topic map meta-model that identifies events; assigning, by the computer, an identification in the first topic map meta-model to at least one association between at least one asset of the topic map meta-model that identifies assets and at least one event of the topic map meta-model that identifies events; creating, by the computer, a second topic map meta-model that identifies at least one association between at least one asset and at least one event in a topic map based index and instance ontology with the direction of impact of the event on an association in various scopes between assets based on an impact of the event on at least one of the assets of the association; in response to a new event being added to the topic map meta-model identifying events, the computer re-creating the first topic map meta-model for the new event and the second topic map meta-model, adjusting the direction of impact associated with the association in the first topic map meta-model, the re-created first map meta-model including a topic map based index and instance ontology for the new event and the adjusted direction if impact; and storing, by the computer, the re-created first topic map meta-model and the re-created second topic map meta-model into a repository.
12. The computer system of claim 11 , further comprising further comprising the program instructions to search, by the computer the first topic map meta-model and the second topic map meta-model stored in a repository, comprising: receiving, by the computer a query input from a user; obtaining from the query input, by the computer, at least an identification of an association between at least one asset and at least one event of in the first topic map meta-model; searching, by the computer, the second topic map meta-model for the identification; and displaying, by the computer, direction of impact assigned to the association in at least one scope to the user.
