The certification on the grid is already awkward, since it is repeatedly performed at every step of the grid job submission. It would be a general expectation from the emerging grid technologies to simplify the certification process significantly, i.e. to make it more similar to the Web Services certification. Another issue related to the phase two is the upload of the data that are to be processed. The design of grid allows these data to be uploaded in advance, and than used by the computing applications as needed. However, this may be not always desirable for the information retrieval. In the context of information retrieval this data is typically the original text of a document.
