- 1. A data processing system comprising at least one data item acquisition unit and at least one data store, the data item acquisition unit comprising a data tag generator for generating a data tag associated with each data item, and the data item acquisition unit being arranged to transmit at least the data tag to the data store.
- 16. A method of processing data including the step of generating a data tag associated with a data item at a data acquisition unit and transmitting at least said data tag to a data store.
- 25. A data item acquisition device comprising a data tag generator and arranged to transmit a generated data tag associated with an acquired data item to a data store.
- 30. A data store arranged to store a plurality of data tags associated with respective data items, and arranged to export, upon request, data tag generator configuration information for use by data tag generators.
-
37. A distributed metadata processing system comprising at least one data capture device and at least one remote data store in communication with the data capture device, the data capture device comprising metadata generation means for generating metadata associated with a captured data item, the data capture unit further comprising communication means for sending the metadata to the at least one remote data store.
-
38. A data processing system comprising at least one data item acquisition unit and at least one remote data store, and in which both the data item acquisition unit and the remote data store include a metadata generator for generating metadata associated with acquired data, the data item acquisition unit further including a decision module arranged to evaluate if the metadata is most efficiently generated at the data acquisition unit or at the remote data store, the data acquisition unit being arranged to transmit at least the either the generated metadata or the data item to the remote data store in response to said evaluation.
-
39. A data processing system comprising at least one data item acquisition unit and at least one remote data store, the data item acquisition unit comprising a data tag generator for generating a data tag associated with each data item, and the data item acquisition unit being arranged to transmit at least the data tag to the remote data store, wherein said data tag generator is arranged to detect a failure to generate a data tag for a data item and in response to said failure to request the transmission of further configuration information held at the remote data store to allow successful data tag generation to occur.
-
40. A method of generating a data tag associated with a data item, the method including the steps of:
-
acquiring the data item using a data capture unit;
evaluating whether to generate the data tag at the data capture unit or at a data store in communication with the data capture unit; and
in response to the evaluation, communicating either the data item or generated data tag to the data store.
-
-
41. A method of generating metadata associated with a data item, the method including:
-
acquiring a data item at a data acquisition unit having a metadata generator;
determining if the metadata generator has sufficient configuration information to successfully generate the metadata for the data item; and
if the outcome of said determination is negative, requesting the transmission of further configuration information from a data store in communication with the data acquisition unit.
