1 JMA's Status Report related to WIS Tatsuya Noyori JMA ET-WISC 2-5 February 2010

2 Contents WIS VPN Pilot Project in RAs II and V Metadata and Catalog Blog software and related technologies

3 Internet VPN

4 JMA Test System WIS VPN Pilot Project in RAs II and V Interne t JMA Operational System RTH Tokyo Met. Sat. Center Supercomputer System for NWP RSMC Data SV. VPN Cloud-I VPN Pilot Proj. DMZ MPLS (OBS) Frame Relay (BT) Etc. DDB SV. Cloud-II (RMDCN) CMA BoM Other PP Participants 100Mbps (Best effort) NAS Main purpose is to evaluate the availability of VPN 17 participants in total Themes in Advanced Phase 1.NC Application (SATAID) 2.Data input support CMA has implemented Web Input and BUFR Encoding JMA is evaluating them

5 Metadata and Catalog

6 Design of Catalog/Metadata What human interface do we need for catalog and metadata? What element do we need in metadata? Let’s learn best practice from existing website.

7 Example: WDCGG JMA World Data Centre for Greenhouse Gases http://gaw.kishou.go.jp/cgi-bin/wdcgg/catalogue.cgi Catalog search, Form Search, Map search

8 WDC (Greenhouse Gasses) There are a lot of domain-specific elements as metadata, such as parameter and contributor and etc. The domain-specific elements are used as search key for search functions. Therefore, the use of domain-specific elements are important to search metadata effectively.

9 Design of Catalog/Metadata learned lesson Usefulness of multiple search interfaces Usefulness of domain-specific search terms and interface (e.g. "parameter", "station type" in WDCGG) Do you think we need VolA/VolC-specific features?

10 Website of Metadata of VolA/VolC http://www.shiken.kishou.go.jp/roller/tokyometadata/ Catalog search, Map search

11 Metadata for bulk data like GRIBs

12 http://www.ecmwf.i nt/products/additi onal/gts_headers _dcpc_essential. html

13 Website of Metadata of Volume C and A The way of writing a file name list of a group in a page enable users to understand the relationship between the files of the group. Therefore, writing a file name list of a group in a page is important.

14 Website of Metadata of VolA/VolC http://www.shiken.kishou.go.jp/roller/tokyometadata/ http://akira.inmet.gov.br/roller/brasilmetadata/ Feed Aggregator: http://en.wikipedia.org/wiki/Aggregator http://en.wikipedia.org/wiki/Aggregator

15 Suggestion for Metadata Atom is one of metadata. KML is also one of metadata. If WMO adopts KML and Atom as one of the metadata, we could easily build the website that I have shown. So, I would like to suggest that WMO adopts KML and Atom as metadata.

16 Website using ISO19139 Metadata http://server.shiken.kishou.go.jp/testwar/search.jsp 70,000 metadata that are created per each static data files have been stored. Full-text search, bounding box search, time range search

17 Website using ISO19139 Metadata ISO19139 does not permit domain-specific elements and tabular listing. So, I am not sure how I can use ISO19139 effectively. But I will keep studying how we can built useful website on ISO19139.

18 Blog software and related technologies

19 Japan has been investigating blog software and related technologies in cooperation with Brazil and China, since 2008. I have investigated Notification of priority messages using blog post File synchronization like podcast

20 Customization of blog software for test The blog software has been customized to reply minimized Atom feeds. The customized blog software has been used for the investigation.

21 Test Results Notification of priority messages It was confirmed that the notification of test tsunami warnings generated on a routine schedule was completed within 20 seconds.

22 Test Results File synchronization The maximum transfer rate was 9Mbps. Messages (SYNOP, SHIP, BUOY, TEMP, TEMP SHIP and PILOT) generated on a routine basis were synchronized within 60 seconds. A product of numerical weather prediction (The total size is 70Mbytes, the number of files is 9116) was synchronized within 150 seconds. A large file of 100Mbytes was synchronized within 150 seconds.

23 Conclusion desirable usage scenes Data providers provide users with data on a near-real-time basis over the Internet. Data providers provide users with data at intervals over the Internet. Data providers receive a priority message from the GTS, and then post the priority message to their blog server on the Internet

24 Suggestion I would like to suggest using blog technologies in WIS Part B (the Internet)

25 Suggestion Timely delivery service can also be implemented by “pull” mechanism using the file synchronization of blog technologies. Therefore, I would like to suggest that the sentence of WIS fundamental services is revised like ”Push or Pull”.

26 Other test I have done Atom+KML metadata synchronization http://www.shiken.kishou.go.jp/roller/tokyometa data/ http://akira.inmet.gov.br/roller/brasilmetadata/

27 Other test I have done Decoded Data (HTML 5 Microdata) synchronization http://www.shiken.kishou.go.jp/roller/tokyomicrodata/ http://akira.inmet.gov.br/roller/brasilmicrodata/

28 Future Plan Investigate PubSubHubbub protocol conduct experiment of scalability
