Slide 2 2

3. Status of Specifications
Collection Catalogue (OGC v0.1.11)
Now maintained by RWG at OGC
INSPIRE conformance class
Relationships services with collections as per INSPIRE MD Guidance.
Aligned of URN with OGC Naming Authority policy OGC
Change Data types to URN to be aligned with Basic Extension Package and ebXML data types
OGC RWG Vote as soon as remaining (Galdos) comments are resolved:
HMA-specific requirements to be moved to Annex
Internationalisation to be put at higher level (CR available)
Clarify if slots are from Basic Package or defined in CIM
Mismatch in slot type for two slots

4. Status of Specifications
OGC r1
INSPIRE Conformance Class of OGC Cataloguing of ISO Metadata (CIM) using the ebRIM profile of CS-W.
EO Application Schema for GML (OGC )
Definition of new schemas planned in HMA-FO for:
Synthesis and Systematic products
Radar altimeter, limb looking products
Analysis and extension of Product Catalogue specification if required.
HMA Product Metadata workshop 29/09/2009

5. Status of Specifications
Collection Catalogue (OGC v0.1.11)
Template defined for service and collection metadata in ISO19139 format and relationship between both. Can be « discovered » through OGC compliant catalogue.
Template checked for INSPIRE compliancy with INSPIRE metadata editor.

7. Status of specifications
Product Catalogue (OGC v0.2.5)
Now maintained by RWG at OGC
Aligned of URN with OGC Naming Authority rules
Change Data types to URN to be aligned with Basic Extension Package and ebXML data types
Approval steps:
OGC RWG Vote: successful
OAB to approve start of electronic vote: underway
Electronic vote

8. Status of specifications
OGC EO Extension of WMS (Infoterra-UK)
Inclusion of Abstract Test Suite
Development of the Abstract Test Suite highlighted a number of minor issues which were addressed.
OGC TC Valencia
Version (21/09/2009) available on public OGC Web site.

9. Status of Specifications
OGC EO Profile for SPS (Spotimage)
Preliminary alignment with draft SPS 2.0 was tested via implementation for optical and radar SPS.
Planned in HMA-FO (Task 2) :
Alignment with the evolving OGC “SWECommon” and SPS 2.0 (OGC )
Completely specify all the operations: GetCapabilities, DescribeTasking, GetFeasibility, Submit, and DescribeResultAccess.
Definition of Abstract Test Suite (ATS)

10. Status of Specifications
OGC Ordering (Elsag Datamat)
Maintenance of the OGC for taking into account new requirements (e.g. Alignment with the latest version of SWE Common, alignment with the SPS EO).
Definition of Abstract test Suite (ATS) planned.
Started RFC for EO Order SWG, during this TC first meeting.

11. Status Specifications
On-Line Data Access – WCS (HMA-FO Task 3 - EOX)
EO Application Profile of Web Coverage Service WCS will be prepared.
Assessment of related activities in INSPIRE will be done (« Download service »)

12. Status Specifications
On-Line Data Access (cont'd)
GSCDA use cases including use of WCS-T and WCPS will be elaborated:
Get a coverage (all scenes, all subscenes, merged coverage)
Add new coverage
Update mosaic
Processing (HMA-FO Task 3)
WCPS (Web Coverage Processing Service)
Is the multi-dimensional WCS raster language
SQL for coverages": ad-hoc navigation, extraction, aggregation, analysis

13. Common Issues OWSCommon alignment Asynchronous behaviour
OWSCommon 1.0 (OGC c1): used by Ordering, EO EP, CIM EP, and SPS EO Profile (0.9.5)
OWSCommon 1.1 (OGC r3): used by SPS EO Profile 2.0
OGC r5: used by OGC Version
OWSCommon 1.2 :vote currently underway...
Asynchronous behaviour
SPS and Ordering specification use different approaches
OGC Naming Authority policies
May have impact on several specifications

14. Current TC Metadata Discovery Ordering On-line Data Access
Presentation "Profile of SensorML for EO" (SWE WG, ERDAS)
Discovery
"SensorML Extension Package for ebRIM Catalogue" (SWE WG, ERDAS)
"Status EO and CIM EP" (CS DWG, ERDAS)
Ordering
Started RFC for EO Order SWG (Datamat)
On-line Data Access
"Online data access in the frame of ESA's HMA Initiative" (Coverages DWG, EOX)
