3. Motivation for the OGC CSW ISO AP 2.0.2
Review existing catalogue standards for the spatial domain
SDIC/LMO reference material (analysis) of DT MD and DT NS
Metadata survey by JRC Distributed catalogue pilot JRC (2006)

Review existing catalogue standards
Existing catalogue standards considered: OGC Catalogue Service for the Web
(CSW) Z39.50 search and retrieval protocol EbXML Registry Service Universal Description, Discovery and
Integration (UDDI)

Reference material analysis on deployment of catalogue standards
• Clear perspective on use of DC and ISO 19115/19119 in metadata reference material of SDIC/LMOs (from DT MD)
• DT NS reference material of SDIC/LMOs show few references on use of catalogue service standards in Europe
• INSPIRE metadata survey by Novak & Cragia (2006)

4. Performance requirements
Performance; The time for sending initial response to service
request in normal situation shall be 3 seconds. This time
includes sending discovery service errors or exceptions. For the
Discovery Service, this time shall allow to send 250 Metadata
records. Normal situation represents periods out of peak load. It
is considered to be 90% of the time.
Availability; The probability of the Discovery Service to be up
shall by 99% of the time, no more than 15 minutes downtime
per day during working hours.
Capacity; The minimum number of simultaneous service requests
served according to the performance requirement shall be 100
for the Discovery Service.

5. Open issues (under discussion in DT NS)
1. Mapping INSPIRE search metadata elements to OGC CSW AP ISO 19115/19119
few INSPIRE metadata elements are not CSW AP
ISO core queryables
2. Mapping INSPIRE search metadata elements to Dublin Core
is under development by DT Metadata
