4. CGMS TF-MI Tasks Facilitate satellite products metadata management
Define guidance documentation and template examples for WMO Core Profile 1.3
Improve user search experience for satellite products
Define set of mandatory attributes to be present per satellite products to provide a meaningful discovery experience to users
Consolidate Satellite providers/users community findings regarding the WIS discovery services
Report resulting outcomes to WMO expert groups
WMO IPET MDRD, ET-WISC

5. 2015 Task Force Deliverables
[Metadata Management]
CGMS Information Model for satellite data (Level 1,2 and 3), including the set of mandatory attributes allowing a user to accurately find a satellite product and obtain from the catalogue a complete description for this product.
Next Step: create XML WMO Core Profile 1.3 mapping and write Metadata guidance documentation.
[Improve User Experience]
WIS Discovery Portal Usability Report highlighting the WIS user interface focus on a specialized user community (GTS) and trouble for finding standard satellite product information out of the technical information.
Recommendations provided to start improving the search discovery and user experience.
Submitted to IPET-MDRD and ET-WISC for review.

6. WIS Portal Usability Report 2016 Outcomes
Report supported by IPET-SUP and submitted to ET-WISC and IPET-MDRD
Creation of a ET-WISC/IPET-MDRD Task Force to start from the CGMS TFMI recommendations and define evolutions on the WIS Discovery Portals
Address how to improve WIS Discovery Services
Focus on Products information presentation
Improve Product metadata content
CGMS TFMI useful to represent a user community in the WIS.

7. WIS Metadata Management WMO Core Profile 1.3 Mapping (1)
Based on the Initial version of information model ,examples have been developed for a number of satellite data sets
FY-3 VIRR Level-1, INSAT-3 AMV Level-2, Himawari-8 AHI Level-1, POES AVHRR SST Level-3, Meteor MTVZA-GY Level-1C
Create a mapping of the full CGMS Information Model to the WMO Core Metadata Profile 1.3
Through this mapping exercise it became evident, that all the information model elements could not be unambiguously mapped to ISO elements.

8. WIS Metadata Management WMO Core Profile 1.3 Mapping (2)
Select information from the model to provide the necessary level of information to create Discovery metadata.
Create a simplified mapping and an initial XML template has been created
An important issue discussed in the TF is whether to represent information directly related to the satellite and instrumentation in the simplified information model,
Elements to be covered by the future WIGOS metadata
Some recommendations of the TF are:
To use the free text field “Abstract” in the ISO Discovery metadata to provide a sufficient level of information regarding the instrument and platform.
Reference (link) additional more complete instrument and platform information from the metadata

9. Guidance Documentation on WIS Metadata Creation (1)
With the mapping, the TFMI has created the Guidance Documentation
Intended for a typical user involved in metadata creation: a product specialist
Based on a Template-based approach where the user has to replace placeholders with the product information
Templates can be used in editing/automatic generation tools
Use Guidance Documentation for additional details
TFMI recommends:
to follow a structure for the Title and Abstracts,
to link additional product information: calibration, detailed product definition,
to reference the corresponding WMO OSCAR Platform and Instrument page.

10. Guidance Documentation on WIS Metadata Creation (2)
Draft Guidance documentation & Template based approach presented during IPET-MDRD workshop in May 2016
IPET-MDRD to adopt the same approach to create the “non-expert” WIS metadata creation documentation
Focus on the product information
Hide the XML and ISO metadata structure has much as possible
Use the CGMS TFMI Guidance Documentation as a basis and extend it with example for additional products: terrestrial stations, GTS bulletins, …
Final IPET-MDRD Guidance documentation to be endorsed by ICT-CTS and published for CBS 16
Great achievement for CGMS TFMI to donate/contribute to the official WMO WIS metadata creation doc

11. Guidance Documentation Next Steps
CGMS Guidance Documentation currently being reviewed/finalized. To be published in June 2016
Additional examples are being created.
CGMS TFMI contribution to the official WMO metadata creation guidance documentation
Until end of July 2016

12. Future Work (1) Metadata Management:
Create additional product examples (Aug 2016)
Create a web based version of the Guidance documentation (end of Q3 2016)
To be discussed: Create a web based tool for validating CGMS-TFMI compliant metadata records

13. Future Work (2)
The WIGOS Metadata standard has been endorsed and is in version 1.01
It is an abstract model that needs to be applied to and translated into an exchangeable format
XML OGC Observations and Measurements used to create WIGOS metadata records
OGC O&M XML mapping has now being published and is in review.
WIGOS OGC O&M profile needs to be reviewed by Satellite product and metadata specialists
Very active Terrestrial station/observation community
Lower involvement from Satellite community

14. Future Work (3)
CGMS TFMI has the expertise to review the WIGOS OGC O&M format
Expertise in Satellite product
Metadata specialist with ISO and OGC standard knowledge
Propose TFMI to review the WIGOS OGC O&M XML format
Create WIGOS Product examples and submit for review to IPET-SUP
Analyze the format
Produce a report with its findings and submit it to IPET-MDRD and the Task Team on WIGOS Metadata (TT-WMD)
Work plan
Sep 2016: Start analysis and product examples creation
Jan 2017: Draft report delivered for review to IPET-SUP
March 2017: Deliver WIGOS Report for comments to IPET-MDRD and TT-WMD

15. Actions/Recommendations
CGMS TFMI to publish the “Guidance Documentation on WMO Core Profile Metadata Creation For Satellite Products” and submit it to IPET-MDRD and IPET-SUP.  
CGMS to endorse the assessment of the WIGOS metadata OGC O&M mapping by the CGMS TFMI and reporting of its findings/recommendations to IPET-MDRD
