The IODE Ocean Data Portal - current status and future

Nikolai Mikhailov, Chair of IODE/JCOMM ETDMP

National Oceanographic Data Centre, Russia

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.”

ODP Structure

ODP V2: Network model Interoperability New functionality and features

ODP V1

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)

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

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.

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

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

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

ODP next steps for 2012-2013General 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
