WMO

  • Development of a WMO core profile of the ISO 191xx series of standards for metadata and data, encompassing the WMO Metadata core profile of the ISO metadata standard, including relevant ISO 191xx feature catalogues, application schema(ta) and data product specification(s);

  • Further develop procedures and guidance for the interoperability of metadata and data, including BUFR, CREX, GRIB, XML, NetCDF and HDF, and liaise with the NetCDF and the Climate and Forecast (CF) communities in this respect , in particular develop and maintain a WMO conceptual data model to facilitate the interoperability of metadata and data;

  • Develop a WMO inter-programme metadata and data representation policy, including governance;

  • Coordinate extensions to the WMO core profile needed to satisfy the requirements of all WMO Programmes;

  • Develop guidance for the implementation and use of the data representation systems, metadata and the WMO core profile, including training aspects;

  • Propose extensions to the ISO 191xx series of standards required for the WMO core profile and liaise with ISO and OGC as required.

Ipet mdi working arrangements l.jpg
IPET-MDI: working arrangements

  • Active engagement within collaboration environment

  • Ad-hoc telephone conferences (specific issues)

  • Meeting expected April 2010


Huddle facilities l.jpg
Huddle - facilities

  • Huddle for Enterprise

    • Huddle’s Enterprise packages offer customisable, secure online workspaces providing project management, collaboration, voice and web conferencing, desktop sharing and document sharing tools.

    • Huddle Enterprise offers features not available within our web packages. Enterprise users can:

      • Enable advanced security including IP and domain restriction

      • Switch on and off certain features of Huddle

      • Add account managers who can create workspaces and set permissions

    • Enterprise Accounts receive a higher level of support from our support team and account managers

    • Enterprise Accounts allow content to be backed up

    • Enterprise Accounts provide toll-free telephone conferencing support for participants … this is not VoIP (like Skype) but normal telephony

IPET-MDI: Interaction with ISO

WMO

  • Working arrangements between WMO and ISO (signed in 2008)

  • WMO was granted the Class A liaison status for participating in the ISO Technical Committee 211 responsible for the 19100 series of ISO geographic information standard

IPET-MDI: Interaction with OGC

WMO

A Memorandum of Understanding (MoU) between OGC and WMO was signed in November 2009

WMO/OGC

Memorandum of Understanding

WMO

The OGC and WMO will support the cooperative development of conventions for using ISO 19100 series of geographic information standards in the respective meteorology, hydrology, climatology, and oceanography communities.

The OGC and WMO will cooperatively develop and publish joint outreach materials designed to promote the mission and standards of both organizations, to include best practice papers on usage of ISO 19100 series of geographic information standard, OGC Web Map Service (WMS), Web Feature Service (WFS), Web Coverage Service (WCS), Catalogue Service for the Web (CSW), Geography Mark-up Language (GML), Sensor Web Enablement (SWE) technology and standards, and others as appropriate.

Ipet mdi vision l.jpg
IPET-MDI Vision

  • To create sustainable data and metadata standards …

  • This means that the standards need to be:

  • as simple as they can be

  • based around standards already in use

  • supported by education and best practice guidance

  • with clear governance measures in place

  • … that meet the needs of WMO’s stakeholder community

We will use ‘use-cases’ based on real requirements to develop the standards; WIS, GEOSS, INSPIRE, Emergency Management, International Red Cross etc.


Ipet mdi initial work plan l.jpg
IPET-MDI: initial work-plan

  • Very ambitious work-plan – too ambitious!

  • Difficulties in arranging initial meeting results in poor coherence of team activity

  • Activities re-scoped & re-scheduled

    • Poor communication from IPET-MDI on potential impacts to OPAG-ISS programme of work – apologies!

Questions from et wisc for discussion l.jpg
Questions from ET-WISC… for discussion …

Urgent need for sample metadata (not just GTS metadata)

Urgent need for guidelines on creating and managing metadata

Agreement on one standard approach between main centres already developing metadata

Agreement on standard mapping of bibliographic terminology (i.e. description/abstract etc)

Urgent need for access to searchable (ISO23950 / SRU) interfaces

Updates on the Member’s and secretariat’s work on GEONETWORK and a need for sharing and coordination of this activity


Questions from et wisc for discussion21 l.jpg
Questions from ET-WISC… for discussion …

Urgent need for sample metadata (not just GTS metadata)

Need for sample metadata is understood.

Anticipate sample metadata elements being included within best-practice ‘manual’

Do you need complete records to ingest into WIS test-systems?

Do you have clear scenarios or use-cases that can be provided to scope the request for metadata?

For IPET-MDI to best support ET-WISC we will need to be provided with a clear understanding of how the WIS infrastructure will operate, the ET-WISC priorities & their perceived barriers to implementation


Questions from et wisc for discussion22 l.jpg
Questions from ET-WISC… for discussion …

Urgent need for guidelines on creating and managing metadata

Guidelines indicating best practice methodologies for construction of metadata records is a current work in progress.

No current activity underway regarding the management of metadata. Defining the process for management of the standards, profiles & vocabularies falls within remit of IPET-MDI – anticipated that management of metadata instances is a GISC implementation concern


Questions from et wisc for discussion23 l.jpg
Questions from ET-WISC… for discussion …

Agreement on one standard approach between main centres already developing metadata

Work in progress … hope to provide verbal update during ET-WISC meeting


Questions from et wisc for discussion24 l.jpg
Questions from ET-WISC… for discussion …

Without additional context provided by scenarios or use-cases I am unable to determine a response to this requirement … please provide more information

Agreement on standard mapping of bibliographic terminology (i.e. description/abstract etc)


Questions from et wisc for discussion25 l.jpg
Questions from ET-WISC… for discussion …

IPET-MDI seeks to accommodate the effort to integrate ISO23950 SRU into the WIS by developing mappings from ISO19115 to the SRU query string

IPET-MDI members have, where possible, identified initiatives within their host organizations that may provide ISO23950 SRU interfaces, but there is no coordinated activity being promoted by IPET-MDI at this time

The Huddle site could continue to be a forum for these discussions?

Urgent need for access to searchable (ISO23950 / SRU) interfaces


Questions from et wisc for discussion26 l.jpg
Questions from ET-WISC… for discussion …

This does not appear to be a core activity of IPET-MDI – should ET-WISC look to co-ordinate experience with GEONETWORK as part of the WIS implementation effort?

Updates on the Member’s and secretariat’s work on GEONETWORK and a need for sharing and coordination of this activity
