A process for the preparation of a 1,1-cyclopropane, the process comprising treating an olefin with an acceptoracceptor-substituted \u03b1-cyanodiazo reagent in the presence of a catalytic amount of a metal porphyrin catalyst. Each feature is extracted from a job model representing the job by invoking a corresponding analytical rule for each feature. Using five basic data structures, one embodiment of the present invention enables the tracking of IP elements, IP assets, metadata elements, log elements, and user records.
