Part III. Appendix 2: Data Transportindependent groups (or individuals) addressing each is important. In addition to these individualgroups there also needs to be a coordinating activity that addresses the integration of the componentsdeveloped as part of these pilots into the system as a whole. Again, we note that integrationof a component into the system as a whole does not mean that that component is being endorsedfor use. It simply becomes a candidate for future adoption. At the same time, we firmly believe thatit is only through actual implementation in the overall system that we will learn the most valuablelessons associated with a given component.We expect that to coordinate the activities outlined below will require between one and two peopleper year. IOOS should budget on the order of $200,000 for this activity. A cautionary note here.This coordination activity is in addition to that associated with the maintenance and evolution ofthe DAP, with the general administration of the data transport effort and with broader user services,and with documentation needs of the transport component as a whole.The following pilots are presented in rank order. In addition, for each pilot we assign a priorityfrom 1 to 10 with 10 being the highest, an absolute must that needs to be undertaken immediately,and 5 being a task that needs to be done but is not critical at the outset, to 1 for a task that wouldbe nice to have addressed, but…Pilot Project #1: The Semantic Data Model –Priority 10We recommend that a pilot project be funded to examine existing semantic data models and, basedon this evaluation, either to choose one or to design one for the IOOS transport component. Wesee this as the highest priority development task that must be undertaken at present.A semantic data model facilitates use of the data. Immediate work must begin on identifying andlayering such a model on the DAP. Several such models either exist or are in development, but theData Transport Team was not able to obtain sufficient documentation on them to make a firm recommendationfor any one at this point. The results of this pilot, a preliminary design or the decisionto adopt an existing system, should be available within one year of the group being formed.The group undertaking this pilot should work closely with OPeNDAP so that the model may readilybe incorporated into the DAP.The data model should also be constructed so that data sets that are not compliant with the datamodel at present can be made compliant in the future without modifying the data.161
