1 The IODE Ocean Data Portal - current status and future Nikolai Mikhailov, Chair of IODE/JCOMM ETDMP National Oceanographic Data Centre, Russia Four Session of the Joint WMO-IOC Technical Comission for Oceanography and Marine Meteorology, Yeosu, Korea, May 2012

2 ODP objectives “The ODP is a standards-based infrastructure to build and manage a distributed marine data network basing on: data and products of the data centers of the IODE, JCOMM and other IOC projects; resources of other participating systems and also provide the discovery, evaluation (through visualization and metadata review) and access to data and products.” IODE Ocean Data Portal concept paper ODP requirements and design decisions

3 ODP Structure ODP V2: Network model Interoperability New functionality and features ODP V1

4 ODP participants provide the operation of three types of ODP nodes: Global Regional/specialized National Technical ODP participants MCDS (GTSPP, …..) can be the data federation of the ODP distributed system connected via specialized node (nodes )

5 ODP Technology Data Cache Integration Server Data Provider Integration, delivery, exchange Portal and portlets GIS server User Serving Monitoring Service Bus System Management Security ODP v2 Interoperability arrangements ODP V2 Tool Kit The ODP participats need to accept and implement a set of agreed interoperable arrangements of information and Web-services interfaces Interoperability specifications: semantic and sintactic

6 Options for ODP node deployment ODP Tool Kit or Global node Regional node National node ODP Data Provider Light or Interoperability arrangements

7 ODP nodes nomination The accreditation mechanism and procedures will be established to govern the process by which the ODP participants can seek formal designation (IODE-QMF) The ODP node accreditation will be carried out along with NODC accreditation process under IODE-QMF and provided by SG-ODP and SG-QMF The capability and performance of an ODP node will be periodically reviewed by the SG-ODP and SG-QMF.

8 Current ODP data providers 13 Data Providers registered 10 Data Providers operational 62 data sets available via the ODP Portal 11 data sets – databases 5 data sets – images (object files) 28 data sets – remote HTTP/FTP inventory files; 18 data sets – structured data files (local);

9 ODP maintenance The ODP technical node (IOC Support Cenre for ODP): develop, host and maintain the tools and specifications of the IODE ODP assist the ODP nodes to achieve their regional and thematic objectives develop, strengthen and maintain the ODP data management training programmes and tools monitor and report on the ODP tools and spec use, impact of the ODP data and services in IOC programmes

10 ODP operation 2.Metadata Generation Synchronization Consolidation 3. Data exchange Notification on events Data unification Data delivery 4. Information services “Map-Plot-Table” GIS - presentation 1.Nodes interconnections Node’s registration Connection with local data

11 ODP Capacity Building 11

12 ODP examples. Connect & Share Local databases, structured and unstructured data files, data inventories (FTP,HTTP)

13 ODP examples. Manage & Monitor automatic data provider nodes maintenance (respectively to the data life-cycle) metadata catalogue update/synchronization/publishing nodes accessibility monitoring, reporting tools and feedback

14 ODP examples. Unification & scalability Use of controlled code lists and vocabulary dictionary (easy to extend and substitute)

15 ODP Examples. Access Search -> Deliver -> View -> Download

16 ODP Examples. Access Profiling -> Deliver -> View -> Download

17 ODP Examples. Access Profiling -> Subscription - Deliver -> Download

18 ODP Examples. Services HTTP-services and Web-services Provides ability to communicate on “machine-to-machine” level Applied tasks service Provides generation of “map-graf-tab” presentation 18

19 ODP Examples. Maps 19 GIS Analysis tool Provides near real-time GIS-layer generation from distributed datasets both with external geo-services interactive and presentation of multidisciplinary data and products on a map

20 ODP next steps for General stable ODP Tool Kit and arrangement specifications IOC support centre for ODP Flexible interoperability (WIS, SeaDataNet, etc.) Technology Expanding of ISO 19139, OGC-standards use IODE ODP – new open source project (Sourceforge, Google code) Feedback and bug tracking system Plug & play software tools for interoperability arrangements Distributed data system and nodes Expanding of data providers Supporting the programme – ODINs, MDCS, WDS ….. Interaction with WIS and SDN
