Functionality is described for providing assets to a client environment, such as a set-top box. The functionality receives a request from the client environment that specifies an original set of parameter name-value pairs. A filtering module filters the original set of parameter name-value pairs to provide a set of germane filtered parameter name-value pairs. A matching module identifies a set of candidate assets which have characteristics which either exactly or partially match the parameter name-value pairs of the filtered set. A matching module resolves partial matches by applying preference analysis. The functionality is advantageous because it provides an intelligent mechanism for supplying assets which match asset requests, without requiring an exhaustive a priori one-to-one mapping between assets and the set-top boxes that can utilize the assets. The functionality also provides a highly extensible design.
