4. HMA Catalogue Specifications
New specifications based on OGC/ISO existing specifications :
OGC r1 - OGC Geography Markup Language (GML) Encoding Specification
ISO 19115:2003 & corrigendum / ISO 19119:2006 & amendment
OGC r3 - OGC Catalogue Services ebRIM Application Profile of CSW
All HMA specifications submitted to OGC (DP, BP) :
OGC GML Application schema for Earth Observation products GML Application Schema for EO Products (0.9.0)
OGC ISO 19115/19119 Extension Package for ebRIM AP of CS-W
Cataloguing of ISO Metadata (CIM) using the ebRIM profile of CS-W (0.1.7)
OGC EO Products Extension Package for ebRIM AP of CS-W
EO Products Extension Package for ebRIM (ISO/TS ) Profile of CSW 2.0 (0.0.3)

5. Collection & Service Discovery
Cataloguing of ISO Metadata (CIM) using the ebRIM profile of CS-W
Specification of :
A catalogue service
for the discovery and management of ISO and ISO metadata
implementing the ebRIM Profile of CS-W
Written by 5 technical partners during HMA-T (Testbed) phase 1 :

6. The Cataloguing of ISO Metadata (CIM) EP for ebRIM CS-W:
CIM Extension Package
The Cataloguing of ISO Metadata (CIM) EP for ebRIM CS-W:
defines a unique way to map the ISO 19115/19119 metadata onto the ebRIM model.
ISO metadata will always be represented the same way, in all Catalogues.
Implementers will be able to deliver really interoperable ISO ebRIM Catalogues
This gives sense to ISO ebRIM Catalogues Federations

7. Catalog Search Resources are Earth Observations.
EO products are described using GML metadata.
Metadata is stored in CSW 2.0 Catalogue.
IONIC has written the “EO Products Data Model for ebRIM Extension Package”, in order to define the EO GML/ebRIM mapping.

9. Operational Implementations
The GMES ground segment provides the “necessary interfaces for requesting and accessing data from national and Eumetsat missions forming part of GMES”. The component publishing these interfaces is named Data Access Integration Layer – DAIL [GAC Paper]
HMA shall permit to integrate EO products, space data with all kinds of other data and information. [ Oxygen objective]

10. HMA-E / HMA-T Phase 2
The HMA catalogue specifications have been designed in and ERDAS has already implemented it into its RedSpider Catalog product.
In order to support activities done within the HMA Data Access Implementation Layer - DAIL implementation contract (Kicked off December 2007), ESA has requested through HMA-E ERDAS to maintain and update one of these specifications (06-131) in 2008 and to set up an HMA reference platform for HMA Catalogue Protocols.
The activities we are proposing here are complementary to the ones done within the HMA-E project.

12. Project Description
The work breakdown for the activities in the HMA-T Phase 2 project is depicted below.
WP1000: Project Management
WP2000: CIM Extension / Promote to OGC
WP3000: Promote EO Extension as OGC Standard
Our proposal should be seen as transverse as possible, complementary to the activities done within Task 3 (Conformance Testing) and will take into account the feedback from Tasks 1 (COTS/OS Implementation) and 2 (Prototypes).
Note that this proposal does not include implementation tasks but ERDAS may implement on its own resources some HMA interfaces and therefore propose to the community reference implementations, in particular for updated HMA Catalogue protocols resulting from the activities we are proposing here.

14. Objectives & Tasks (07-038) WP : CIM Extension / Promote to OGC
The objective of this work package is to define, set-up and manage a new OGC Specification Working Group dedicated to the specification regarding HMA Catalogue (RIM extension package for ISO – CIM EP) including :
• Write the adhoc charter
• Launch within the OGC & HMA communities the SWG
• Propose to manage the SWG (chair)
• Propose to lead the SWG (editor)
• Prepare and attend to SWG conf call bi-weekly
• Attend to SWG meetings during TC OGC
In the frame of this SWG, the CIM :
• Will be improved to fulfil generic ISO 19115/19119 metadata requirements
• Will be improved to allow extension of the model
• will be extended for the EO needs with ISO
OUTPUT OF WP:
• Updated document of CIM Extension Package
• SWG for this document, with the objective of proposing this document as an OGC standard
TASKS SPECIFICALLY EXCLUDED: Development of CITE test scripts
Slide 14

15. List of actions
1) Follow the Catalog 3.0 and subsequent revisions of Catalogue Service and ensure an evolution coherent with the CIM extension package.
2) Extend the model defined in the CIM
a) Increase the properties mapped in the CIM to fulfill more requirements from GIS community
b) Define a method to extend the CIM to fulfill additional requirements without breaking the interoperability
c) Define Stored queries to allow easier interoperability with CS-W ISO clients and easier query on the model
3) Investigate link between CIM & EO Extension Package
4) Develop these documents in OGC WG and submit as candidate Implementation Specification

There is one comment to be discussed during contract negotiation:
the travel budget has to be checked.
6 travels and 6 per diem for ERDAS for this project
