1 CGMS WMO Task Force on Metadata Implementation Progress Presented to IPET-SUP agenda item 12.2

2 Overview CGMS-WMO-Task Force on Metadata Implementation Refresher Why such Task Force Task Force goals CGMS-WMO Task Force MI Progress Creation of WIS Metadata creation documentation WIS Portal Usability Report Slide: 2

3 Focus on some WIS Goals Open access to meteorological products to a much larger community: Unlike GTS, no need to be part of the WIS to get the data Will favour the creation of cross-domain synergies To increase the volume of data exchanged within WMO framework: Going away from GTS practices (bulletin, routing) will allow to control larger data exchanges While maintaining the interfaces and services of the GTS WIS Benefits for Satellite data: Provide a better access for all users to satellite products Allow to cope with the increase of satellite product volumes in the next decade Slide: 3

4 WIS Implementation Status Operational since 10 Feb 2012: 15 operational GISCs 54 operational DCPCs 223 operational NCs Operational exchange of data intended for global exchange Operational exchange of metadata records based on a profile of ISO metadata (WMO Core Profile 1.3) to build the catalogue of products amongst GISCs Users can discover and retrieve products Slide: 4

5 WIS from the user point of view It is not easy to consistently find products amongst the different WIS Discovery Services implementations There is a large potential to improve the WIS Discovery services when compared to industry search engines: The WIS could mimic the existing search engine interfaces to provide the best possible search experience No generalised use of a standardised product categorisation allowing new users to understand what is in the catalogue Metadata Product description is often incomplete On-going development to enhance the usability of discovery services: Provide guidance on how to search products Metadata structure (XML) is often visible in the results and prevents users from focusing on the product description itself Slide: 5

6 Improving usability of WIS for Sat Data WIS is very attractive and Satellite Operators can benefit from the WIS objectives Work still needs to be done to make full use of the WIS by Satellite Operators: To make Satellite Data available via the WIS To allow users to discover more satellite products via the WIS The CGMS Task Force on Metadata Implementation (CGMS TF-MI) has been created to help CGMS members to get benefits from WIS Slide: 6

7 CGMS TF-MI Goals (1) Increase the participation of satellite data providers in the WIS: Contribute to WIS and build an attractive one-stop-shop to discover and access Satellite products Use the TF-MI as a forum for discussing matters concerning the WIS from a user s perspective: Promote the usage of WIS for Satellite data providers and facilitate their contribution Relay consistent and consolidated views from the Satellite Providers to the WMO WIS implementation groups: Provide inputs regarding metadata matters to IPET-MDRD Provide inputs regarding the WIS implementation to ET-WISC Slide: 7

8 CGMS TF-MI Goals (2) To get more benefits from the WIS Discovery Services for Sat Operators: Improve Sat product description and consolidate it amongst the providers to make it more coherent for the users Facilitate satellite products metadata management Gap analysis between WMO Core Profile 1.3 and other ISO profiles used by the satellite data provider Deliver road-map to unify profiles when possible Slide: 8

9 CGMS TF-MI Tasks Improve user search experience for satellite products Define set of mandatory attribute to be present per satellite products to provide a meaningful discovery experience to users Define guidance documentation and template examples Relay satellite data user s view regarding the discovery experience on WIS Portals. Report resulting outcomes to IPET-MDRD, ET- WISC Slide: 9

10 Build Metadata Creation Documentation Phase 1: Define list of mandatory attributes To create a meaningful discovery phase To provide the information for understanding the product To allow users to compare different products Phase 2: Create guidance documentation Map information model to ISO format Create a guide for creating the metadata Create examples for the most representative satellite products Phase 3: Create tools Validation tools

11 Guidance Doc Creation Schedule Update Phase 1: Definition of essential elements is complete From Oct 2014 until March 2015 Outcome: CGMS-TF-MI- SatelliteDataProductEssentialInformationForDiscovery Metadata_v1.0.docx Document Presented during the CGMS-43 WG-IV Submitted for information to ET-WISC and IPET-MDRD Submitted for review and comments to ET-SUP

12 Information Model for Essential Information

13 Information Model It is organized around 4 classes of information: Product Information Product description, information Corner-stone of the model as the others information categories are associated to the Product Information Product Distribution Information How to access the product and how is it distributed (file, format, size, ) Satellite Information Instrument Information

14 Metadata Doc Creation Next Steps (1) Map the list of essential information to ISO Find a place holder in the ISO format for each piece of information It might not always be possible! When not possible ask for an extension In ISO Earth Observation Profile Or in WMO Core Profile In the new version to be derived from ISO In the current version Submit those potential modification to IPET-MDRD Work on new version to start Q4 2015

15 Metadata Doc Creation Next Steps (2) Creation of a guide for generating WIS discovery metadata for Satellite Products Description and examples for tricky parts such as data policies and data intended for global exchange, Creation of templates and examples for the most representative satellite products Set of XML templates Make examples available from the CGMS web site and/or the WMO web site To be ready by end of 2015 Phase 3: Provision of tools to validate satellite data providers metadata

16 WIS Portal Usability Report CGMS TFMI can be used as a forum to provide feedback from the satellite data providers users as WIS users Users and CGMS TFMI experts have expressed recommendation concerning the WIS Portal usability They have difficulties to find products on WIS Portals They do not always understand the user interface choices Available in CGMS-TFMI-WMO-WIS-Portal-Usability- Report_vxx.docx Submitted to ET-WISC for review and comments ET-SUP for information

17 Main Findings of the WIS Usability Report (1) WIS Portal UI and discovery is not focusing on products Search results do not always provide information regarding the product, how to access it GTS bulletin ids returned, Discovery UI on WIS Portal are complex Try to re-create new search experiences when users expect the same experience as when using the main search engine Create homogeneity between the different WIS portal search experience Users are redirected to another WIS portal in case of issues Difficulties if portal user interfaces are very different

18 Main Findings of the WIS Usability Report (2) Better search results are needed Search results are often not related to the search This is partly due to the low quality of metadata Automated generation This is why CGMS TF-MI is extremely relevant Regenerate meaningful metadata for all GTS bulletins and satellite DCPC products Better present products to first time users Make use of categorization to guide search experience Facetted search or Browse by navigation Use PAG Domain categorization for satellite data products

19 Conclusion CGMS-WMO TFMI Work is essential to make the WIS infrastructure more attractive for Satellite data provider Satellite data products users
