1. A method of determining an impact of an event identified in a first topic map meta-model will have on at least one asset identified in a second topic map meta-model representative as a weight, the method comprising the steps of: a computer creating a third topic map meta-model which maps at least one asset from the second topic map meta-model to an event from the first topic map meta-model, the third topic map meta-model comprising: a topic map representation of assets of the second topic map meta-model, the second topic map meta-model further comprising a topic map based index and instance ontology of a meta-model of assets; a topic map representation of events of the first topic map meta-model, the first topic map meta-model further comprising a topic map based index and instance ontology of a meta-model of events; identification of at least one association mapped between an event identified in the first topic map meta-model and at least one asset identified in the second topic map meta-model; and weight associated with the identification and assigned to the at least one-association between an event identified in a first topic map meta-model and an asset identified in a second topic map meta-model in various scopes; the computer receiving a query input from a user identifying an event; the computer obtaining from the query input, at least an identification of an association between at least one asset and an event in the third topic map meta-model; the computer searching the third topic map meta-model for the identification from the query input; the computer displaying all weights assigned to the association between the event in the first topic map meta-model and at least one asset of the second topic map meta-model in at least one scope to the user.
