5. HMA-T WP-2: mapping concept CIM AP - ISO AP (INSPIRE context)
Specification / Documentation
Documented CIM AP vs ISO AP interoperability/mapping concept
as official OGC CR for the OGC Cataloguing of ISO Metadata (CIM) using the ebRIM profile of CS-W specification
Deliverables
OGC CR (OGC ): ISO Metadata Profile Conformance of OGC Cataloguing of ISO Metadata (CIM) using the ebRIM profile of CS-W
Slide 5

6. HMA-T OGC CR (OGC 08-197): Minimal and Inspire Conformance Class
Full support of all objects (ExtrinsicObjects, Associations, Slots etc.) in queries and resultsets and
a full support of all filter capabilities often not possible
Two conformance levels (Inspire and Minimal) of the CIM are described which restricts the amount of ExtrinsicObjects, Associations, Slots and filter capabilities
Slide 6

7. HMA-T Minimal Conformance Class
If existing (legacy) catalogue has very limited query capabilities
catalogue carrier can provide its metadata for harvesting purposes to CIM AP clients
Allows simple iterations through the registry content
harvesting of metadata in ISO format
Metadata / ebRIM model for Minimal Conformance Class
Slide 7

8. HMA-T Minimal Conformance Class – Operations GetCapabilities
to be implemented as described in [OGC07-110]
Problem: not possible to describe in Capabilities document which conformance classes are supported.
Solution: operation constraint within capabilities document to describe supported conformance classes
<ows:OperationsMetadata>
<ows:Constraint name="ConformanceClasses">
<ows:Value>Minimal</ows:Value>
</ows:Constraint>
</ows:OperationsMetadata>
GetRecords
Standard use-case: iteration with empty query through whole results is standard use case
A few queryables defined
Slide 8

9. HMA-T typeNames fixed (wrs:ExtrinsicObject, csw:Record)
logical operators, aliases and associations not supported
Supported comparison-operators only:
PropertyIsEqualTo, PropertyIsLike
elementSets “brief”, “summary”, “full” for types wrs:ExtrinsicObject” and “csw:Record” supported.
GetRecordById + DescribeRecord
Not supported
GetRepositoryItem
used to retrieve repository item by "id" attribute of DataMetadata ExtrinsicObject
Repository item is ISO19139 document (see OGC CSW AP ISO 1.0)
Only one identifier can be retrieved at once
Not a valid ebRIM CIM profile/class!
Slide 9

10. HMA-T Inspire Conformance Class
main idea: metadata and service model which is semantically aligned with the Inspire Discovery Services
comprises exactly those CIM AP RegistryObjects and operations which:
are required to map all Inspire discovery requests to CIM AP requests
maximally those which can be mapped from CIM AP requests to Inspire requests
are required to map all Inspire discovery responses to CIM AP responses
maximally those which can be mapped from CIM AP responses to Inspire responses
defines an OGC conformant profile of the CIM AP
does support all mandatory RegistryObjects and service capablities
does not consider some optional elements
Defines no extensions (except additional constraints)
requires the mandatory operations and bindings
Slide 10

11. HMA-T
Inspire Conformance Class
Information Model
Slide 11

12. HMA-T Metadata / ebRIM model of Inspire Conformance Class
The following objectTypes for DataMetadata are supported:
ElementaryDataset, a dataset not having any subset
DatasetCollection, a collection of datasets sharing the same product specification
For ServiceMetadata the objectType is “Service”
maybe objectType ‘Application’
Only DataMetadata and ServiceMetadata are linked to RepositoryItems.
metadata model does assure that:
mandatory Inspire queryables can be mapped to CIM AP (Inspire) queryables
minimally needed ISO19139 elements (to create valid Inspire resultsets) can be filled by CIM AP (Inspire) slots or classifications
For optimzed performance in a ISO AP <-> CIM AP bridge
These are provided when asking for a „full“ resultset.
The next figure shows this mapping

14. HMA-T Operations of Inspire Conf. Class GetCapabilities
operation constraint used:
<ows:Constraint name="ConformanceClasses">
<ows:Value>Inspire</ows:Value
</ows:Constraint>
GetRecords
Supported typeNames in query:
wrs:ExtrinsicObject
rim:Association
rim:RegistryObject
rim:Classification
CSW 2.0.2: csw:Record
Aliases used if more than one instance of type in query
Mandatory queryables in table
GetRecordById + DescribeRecord
as defined in OGC
Slide 14

15. HMA-T CIM extensions for mapping additional Inspire queryables to CIM
Defined new RegistryObjects for additional Inspire queryables
New Association "metadataPointOfContact"
new ExtrinsicObject "QualityConformanceInformation" with slots specPass, specTitle, specDate and a DateType classification (DateType classification schema)
New Association "specification" between "ResourceMetadata" and "Quality-ConformanceInformation"
mapping additional Inspire queryables to CIM additional registry objects
Mapping ISO elements to new RegistryObjects:

16. HMA-T ATS Minimal Conformance Level:
Is part of the Compliance Test Suite for the CSW AP ebRIM EP CIM 0.1.9
The figure shows the dependencies among the specifications involved
Parts of this ATS can be part of Compliance Test Suite for the CSW ebRIM CIM
organized into two conformance levels (Minimal and Inspire)
within Conformance Levels different Conformance Sub-Levels are defined
Minimal Conformance Level:
not a CSW ebRIM CIM conformant class
Slide 16

17. HMA-T For tests no external test data is needed
Implementations must assure to deliver minimally 1 record on empty query
Interface- and Binding-Availability (Level 1.1)
assertions for testing mandatory operations GetCapabilities, GetRecords and Get-RepositoryItem and mandatory protocol bindings are supported.
independent from metadata
Correctness of Request- and Response-Structures (Level 1.2)
assertions for testing if XML structures of request elements (e. g. filter expressions) and of response documents are valid
Slide 17

18. HMA-T Inspire Conformance Level CSW ebRIM CIM conformant class
for this Level conformance to the Minimal Conformance Level is mandatory
The GetRecordById- and the DescribeRecord-Operations are additionally considered.
For tests no external test data is needed
Implementations must assure to deliver minimally 1 record on which is conformant to the metadata model of the Inspire Conformance Class with a boundingBox defined
Slide 18

19. HMA-T Inspire Conformance Level
Correctness of Request- and Response-Structures - mandatory CIM elements (Level 2.1)
assertions for testing XML structures of request elements (e. g. filter expressions) and response documents
additionally tests some mandatory CIM elements in filter expression and resultsets.
Correctness of Request- and Response-Structures - mandatory CIM / Inspire elements (Level 2.2)
additionally tests some mandatory CIM / Inspire elements in filter expression and resultsets.
Correctness of Request- and Response-Structures - mandatory CIM services elements (Level 2.3)
tests some mandatory CIM elements concerning services in filter expression and resultsets
Slide 19

23. HMA-T Interoperability CIM AP - ISO AP
1. ISO AP client accessing a CIM AP service
All requests of ISO AP clients can be mapped to CIM AP servers and all ISO AP responses can be filled from CIM AP responses
Slide 23

24. HMA-T Interoperability CIM AP - ISO AP
2. CIM AP client accessing an CSW ISO service
Problem: impossible to map all CIM AP requests to ISO AP requests and all CIM AP responses to ISO AP responses
Solution: CIM AP / Inspire Conformance Class restricts the CIM AP to those capabilities and information objects which can be mapped to CSW ISO
Now: all CIM AP requests can be mapped by a facade in front of ISO AP server to ISO AP requests (and all their responses to CIM AP responses)
With such a facade every Inspire ISO AP catalogue service can act as a CIM AP (Inspire Conformance Class) Catalogue.
Slide 24

25. HMA-T Usage of CIM AP Minimal Implementations by CIM AP Clients
Main focus of CIM AP Minimal is to allow legacy catalogue carrier to provide its metadata for harvesting purposes to CIM AP clients
