1. A method for implementing a service oriented architecture industry model repository comprising a meta-model service associated with a physical asset repository, the meta-model service comprising: at least one topic map meta-model with data specific to a particular topic or industry vertical included within an information model repository common meta-meta-model, the information model repository common meta-meta-model included within a meta-meta-meta-model with a topic map based index, the method comprising the steps of: a computer assigning topics, occurrences, and attributes from the meta-model service to the at least one topic map meta-model; the computer assigning the topics, occurrences and attributes from the at least one topic map meta-model to a plurality of temporal scope topic map meta-models, wherein a first temporal scope topic map meta-model represents a state of the at least one topic map meta-model at a first time, and wherein a second temporal scope topic map meta-model of the plurality of temporal scope topic map meta-models represents a state of the at least one topic map meta-model at a second time; the computer converting the topics, occurrences, and attributes from the plurality of temporal scope topic map meta-models into resource description framework triples; and the computer persisting the resource description framework triples into a resource description framework repository.
