1. HMA for Science Cataloguing of ISO Metadata (CIM) using the ebRIM
profile of CS-W (ebRIM CIM)
SRR Meeting
16 May 2013, ESRIN Frascati
Uwe Voges, con terra GmbH

2. Why is CIM/I15 package part of HMA-S ?
CIM / I15 not in final status - although officially supported standard in HMA
Lots of inconsistencies
Neither OGC Best Practice nor OGC standard
Finalize things before starting new…
Needed for interoperability with INSPIRE discovery services
Needed for the use case of deep searches:
and/or… 1:n…associations…classifications…
Examples:
EUMETSAT PN
return all services of type WMS version 1.3 operatingOn the datasets X,Y,Z which are all more recent than having a specific resolution
-> typical use-case in sdi´s
Simple Search use
OpenSearch version for Collection Search not yet available …

5. I15 Specification and OGC Adoption (WP5100)
16 May 2013
HMA-S SRR

6. I15 Specification and OGC Adoption (WP5100)
Main Parts of the Specification Document done (except Examples and ATS):
Imported old UML Diagrams from IGN via XMI into Enterprise Architect
Revised all UML-Diagrams
Added new:Quality- and Acquistion Parameters
Updated and Extended the following listings in the spec:
Classification Schemes
Slots
Associations
Data Dictionary: updated, extended
ISO2RIM-mappings: updated, extended, unnecessary overhead dropped
Updated the whole document:
included requirements (alignment with OGC Policies)
I15-Package definition (XML) done

7. I15-Model I15-Model: Re-Modelled main resource metadata types
Regarding SMAAD CRs: simplification and unification of main resource-metadata types: ElementaryDataset, DatsetCollection, ServiceMetadata and Application  
Better alignment with CSW AP ISO
16 May 2013
HMA-S SRR

8. I15-Model
Correct assignments of slots, classifications and associations to the main resource-metadata ExtrinsicObjects objects
Better alignment with CSW ebRIM Basic Package (BP) and the basic RIM 3.0 model (e.g. usage of slots and types introduced in the BP)
Simplifications (resulting: easier filter requests), e.g.
prevention (as far as possible): classification of classifications
main resource-metadata ExtrinsicObjects derived from ResourceMetadata
Simplified associations
Dataset and Service (from BP) needed for interoperability with BP - but not integrated into I15 model
makes model more complicated with no additional benefit for I15
Following example shows the difference between Filter requesting for Service operating on ElementaryDataset (with specific identifier)
=> old CIM / new I15 Model

9. Old CIM Filter - New I15 Filter
I15-Model
Old CIM Filter - New I15 Filter
16 May 2013
HMA-S SRR

10. I15-Model Not only simplyfication, also extensions…
Included OWS9 data quality extension
Better aligned with OGC “EO Product Collection, Service and Sensor Discovery using the CS-W ebRIM Catalogue”, Version: 1.0.
Additional ISO elements (e.g. slots supplementalInformation, explanation,…)
Included Acquisition parameters
=> In the following only those UML diagrams shown which diverge mainly from the old CIM spec

HMA-S SRR

11. UML: Resource Metadata
ResourceMetadata: abstract base class of all information resource types
Improved Slot assignments to better align with resource types hierarchy
16 May 2013
HMA-S SRR

12. UML: Keyword and Thesaurus Information
Every I15 metadata resource entry may be classified by different kinds of keywords
resulting from a list of predefined or thesaurus based keyword schemes
Considers CR derived within SMAAD regarding advanced thesaurus / keyword approach
16 May 2013
HMA-S SRR

13. UML: Data Metadata
metadata resource describing data is defined by an ExtrinsicObject ElementaryDataset or a DatasetCollection
both derived from the abstract ExtrinsicObject DataMetadata
DataMetadata is also having an association to the Dataset ExtrinsicObject defined in the BP (just for BP alignment).
16 May 2013
HMA-S SRR

14. UML: Service Metadata
metadata resource for service metadata is defined by ExtrinsicObject ServiceMetadata
derived from the ExtrinsicObject ResourceMetadata
having an association to the ServiceOperation ExtrinsicObject
having an association to the ebRIM Core Service RegistryObject (and so to additional information defined in BP).
16 May 2013
HMA-S SRR

15. UML: Application
Metadata describing application metadata is represented by an ExtrinsicObject Application
16 May 2013
HMA-S SRR

16. UML: Data Quality
metadata resource may have quality information assigned described by the ExtrinsicObjects DataQuality, Lineage, Source, ProcessStep, ServiceMetadata, CitedItem and Organization.
from OWS9:
defined in OWS9 document OGC

17. UML: Acquisition Information (19115-2)

23. ISO2RIM Mapping
ISO: metadata record is instance of class MD_Metadata (or a subclass)
Each metadata record requires:
creation of MetadataInformation ExtrinsicObject to handle information related to the metadata record itself
creation of ExtrinsicObject instance derived from ResourceMetadata
defined how to deduce which ExtrinsicObject (ElementaryDataset, DatasetCollection, Service, Application) has to be created
describes mapping between the I15 EP model and ISO 19115(-2)/ metadata (ISO19139 encoded)

24. ISO2RIM Mapping
Another example: Acquisition Information (included in ISO metadata record) to I15

Concentrate on testing the I15 package not the ebRIM Spec
Update of I15 EP ICC Abstract Test Suite (if required)
Later
Update of I15 EP Executable Test Suite
Updates of IGN-F/ERDAS test cases from HMA-T Phase 2
Concentrate on testing the I15 package
10-15 test cases

28. I15 ATS/ETS (WP5200)
CIM EP ETS to be executed with the TEAM Engine against an updated version of the Buddata CIM EP reference implementation.
test results will be reported (HMA-S.CTR.D )
If problems occur - CTL scripts (and possibly CIM EP specification) will be updated or Intecs will be informed to change reference implementation
CIM EP ICC ETS exe-cuted by TEAM Engine against HMA CIM EP Bridge
Test results will be reported.
If problems occur in CTL scripts the CIM EP ICC spec and/or bridge implementation will be adjusted.

Not started yet
Outstanding:
Update CIM2INSPIRE Bridge (developed in the SMAAD project) to changes of I15 EP ICC
Bridge be installed in front of the EUMETSAT ProductNavigator which provides an INSPIRE_DS Server
Bridge used by demonstrator client and TEAM Engine (for testing)
No paper work, update of Demonstrator client done by SPB

30. Questions + Issues
What was the reason for further support SOAP 1.1 ? (only 1.2 supported in ebRIM base spec)
Looking for latest ETS: got one from Lorenzo but I´m not sure if it is the latest.
ATC in spec document of CIM not aligned with ETS…
Not clear how to define the slots in the Package Description.
Does anyone have a sample showing this ?
