6. Applicable 2012 UWG Recommendations • Recommendation 24 – Harden tools: Closed. (Tool improvements have focused on stability, debugging, and updates, along with selected re-architecture to improve maintainability.) • Recommendation 25 – Improve linkages between tools and datasets: Closed. (Links to applicable tools and services now exist on the dataset information pages (access tab) in the beta site.) • Recommendation 27 – Harden HITIDE and add datasets: Partially Closed. (The HITIDE interface has been reworked and functionality has been standardized. Extraction methods are still being worked and datasets will continue to be added.) • Recommendation 28 – Decommission POET: Open. (Decommission is pending the addition of all datasets from POET into THREDDS. Updates and testing are in progress.) • Recommendation 29 – Add datasets in THREDDS: Partially Closed. (Applicable datasets from the recommendation have been made available. Datasets will continue to be added.) • Recommendation 34 – Report on how UWG Homework shaped FY13 activities: Closed. (The UWG homework responses aligned with our development goals, but additionally served as a vetting document for evaluating updates.)

7. Outline Purpose of this Presentation: Data Access Mechanisms Status • Provide a functional overview and architectural response Presentation Outline: • Technology mapping and infusion • Current status + Outlook of each functional area: • Direct Data Access • High Level Access Tools • Web Services

10. Direct Data Access: FTP • Standard way of doing business • Our most popular means of access • High degree of user-dependency

11. Direct Data Access: OPeNDAP • Widely used in the Earth Science communities 25

12. Direct Data Access: THREDDS • Popular capability in Oceans and Climate communities • Specifically requested by the UWG 29

13. Direct Data Access: FastCopy • File transfer mechanism requested by specific partners • Alternative to FTP

15. Web Services: Consolidated Web Services (CWS) • New paradigm for PO.DAAC (unsilo’ing) and our Users • Better exposes PO.DAAC’s services • Allows users to quickly write their own clients • Provides flexibility and agility New 25

16. Web Services: Publish / Subscribe • New paradigm for users • No longer have to crawl the FTP site • Improves client’s ability to customize their processing New 25

18. High Level Access: Dataminer • Selected for extraction capabilities • Developed externally • Limited ability to modify software

19. High Level Access: HITIDE • Fills need for Level 2 extraction • Refactors and expands upon Dataminer'sfunctionality New 27 24 34

20. High Level Access: LAS • Fills need for Level 3 capabilities • De-facto standard in the Ocean Science community • Helps with decommission of POET New

21. High Level Access: POET • Provides access and extraction of Level 3 data • Getting expensive • LAS is a more broadly accepted alternative 28
