1. Discovery service testing according to
INSPIRE implementing rules
Tomas Kliment
This presentation has been transmitted remotely as TELE lecture
from ISPRA (IT) using „BizBiz-Tool“ via University of RIGA (LV)
GI2010 – Symposium
Dresden – 14. May 2010
14.05.2010 10. Sächsisches GIS-Forum 1

2. Objectives of this presentation
INSPIRE requirements for discovery service - DS
Proposals for DS testing procedures against
INSPIRE rules
Practical testing of DS from Slovak Environmental
Agency – SEA – testing environment
Testing outcome and future work
14.05.2010 10. Sächsisches GIS-Forum 2

3. INSPIRE requirements
Main documents related to DS
Directive 2007/2/EC establishing an INSPIRE
Legal framework – define WHAT and not the HOW
Commission regulation 976/2009 regarding Network Services
Legal framework – implementing rules - WHAT
Technical guidance for INSPIRE discovery service
Support document – define HOW DS should be implemented
Requirements
Search criteria – Article 11(2), Annex II Part A, Paragraph 2.4
Operations - Article 11(1),12, Annex II Part B, Paragraph 2.3
Quality of DS - Annex I
Multilingual aspects – at service/content level - Paragraph 2.5

4. DS Testing procedure proposals
DS End-point Aquiring
GetCapabilities
POST, SOAP endpoints
Testing procedure launching
GetDiscoveryServiceMetadata
Response validating
DiscoverMetadata
All metadata records
Each Queryable
Language queryable
Metadata quality
Validation – gmd, INSPIRE
Metadata quantity
14.05.2010 10. Sächsisches GIS-Forum 4

5. Testing procedure performance
GetCapabilities request – HTTP GET KVP
http://globus.sazp.sk:8080/soapservices/CSWStartup?Service=CSW&request=GetCapabilities
POST SOAP Capabilities URL
POST XML Capabilities URL
14.05.2010 10. Sächsisches GIS-Forum 5

6. Testing procedure performance
Operations + queryables testing – POST SOAP
deegree Generic OGC WebService Client
ERROR - Unexpected failure: HTTP/1.1 500 Internal Server
Error
Service side error – NO - BUT - client side error - YES
14.05.2010 10. Sächsisches GIS-Forum 6

7. Testing procedure performance
Problems with SOAP REQ from deegree client
SoapFault
No SOAPAction
header
value=URI
within WSDL docs
Client MUST use it
deegree does not
SOAPAction added
OK
14.05.2010 10. Sächsisches GIS-Forum 7

8. Testing procedure performance
GetDiscoveryServiceMetadata response
Validated against OGC schema with XML Spy
http://schemas.opengis.net/csw/2.0.2/CSW-discovery.xsd - VALID
Discovery service metadata
Missing values for elements: Fees, AccessConstraints,
Additional queryables advertised – YES
Federated Catalogues advertise – YES
Currently no federated catalogues
Language mutation of GetCapabilities
Currently no links to language specific capabilities doc.
14.05.2010 10. Sächsisches GIS-Forum 8

9. Testing procedure performance
DiscoverMetadata request
LanguageQueryParameter added to each request
DiscoverMetadata response
All queryables supported
Content cached = 942 records
Multilingual aspect at content level – supported
Only “slo” metadata
942 records discovered 0 records discovered
14.05.2010 10. Sächsisches GIS-Forum 9

10. Testing procedure performance
Metadata quality – validation against gmd
http://schemas.opengis.net/iso/19139/20060504/gmd/gmd.xsd
940 records valid
2 not valid
14.05.2010 10. Sächsisches GIS-Forum 10

11. Testing procedure performance
Metadata quality – validating against INSPIRE
Sample MD sets validated via online INSPIRE
metadata validator
Development of “simple” Java program for MD
validating using INSPIRE Validator Service
Automatic reading XML metadata records from folder
Validating using INSPIRE Validator Service and creating Validation report
14.05.2010 10. Sächsisches GIS-Forum 11

12. Testing procedure performance
Pilot quality testing
Performance – GetRecordByID GET KVP request
Test case runs: 100x
Average response time: 0.952s
Max response time: 3.770s
Min response time: 0.573s
