Part II. Phased Implementation Plan for DMAC- Category: Committee work• Deliverables: Functioning demonstration for review.• Estimated Resources:• Schedule: Year 2• Sequencing:• Partnerships: Interim Standards Committee, User Support team, semantic web experts.7. Activity: Design and Implement Data Location Service• Description: The end result of the Data Discovery process should segue seamlessly into theData Transport (access) process—either the: (1) DMAC middleware connection, (2) on-linebrowse (visualization and subsetting), or (3) web file transfer (e.g., FTP). On-line, distributeddata are dynamic in the sense that the point of access for data may move, and fine granularityinformation about the data sets may not be available in the catalog (e.g., the catalog cannothave the ability to perform GIS-style proximity queries about available data). The Data LocationService will be a standard machine-to-machine interface which enables the seamless segue fromData Discovery to Data Access.• Milestone 1: Determine specifications for data location service.- Task 1: Determine specification for finding path to the requested data (e.g., the directoryon the file server in the data archive).º Category: Contract(s) or RFP- Task 2: Determine specification for finding individual granules of requested data (e.g. theindividual files which satisfy user request)º Category: Contract(s) or RFP• Milestone 2: Data Location Service pilot projects- Category: Pilot projects with collaborating data suppliers and catalog services• Milestone 3: Broad Deployment of Data Location capability- Cross cut: jointly with “population” of DMAC middleware solution• Deliverables:• Estimated Resources:• Schedule: Year 2 or 3• Sequencing:• Partnerships: User Services83
