SHARING METADATA ACROSS

Metadata catalogue – Core of
SDI
Metadata and catalogue services are a
fundamental part of a spatial data
infrastructure. They allow the end user to
discover, evaluate and use the available data
and services. They are the main entry point
into the infrastructure. The three initiatives and
European projects studied in GIGAS have thus
set up catalogue services giving access to
metadata instances.

Metadata catalogue – Core of
SDI
They make use of ISO, OGC and OASIS
standards and other documents on the topic of
metadata and catalogue services:
Dublin Core,
ISO 19115/19119/19139,
OGC GML,
OASIS ebXML,
OGC CS-W. (from GEOSS, INSPIRE, GMES , SEIS interest group GIGAS Technology Watch on
INSPIRE forum)

HSRS Contribution - Micka
MicKa is a complex system for metadata
management used for building Spatial Data
Infrastructure (SDI) and geoportal solutions. It
contains tools for editing and management of
metadata for spatial information, web services
and other sources (documents, web sites,
etc.). It includes online metadata search
engine , portrayal of spatial information and
download of spatial data to local computer.

HSRS Contribution - Micka
MIcKA is compatible with obligatory standards
for European SDI building (INSPIRE).
Therefore it is ready to be connected with
other nodes of prepared network of metadata
catalogues (its compatibility with pilot
European geoportal is continuously tested).

OneGeology
The Geological Metadata Catalogue,
developed within the framework of the
OneGeology-Europe eContent plus project,
provides the means for searching (Metadata
Search) national geological and applied
geological map data ranging from the scale of
1:10,000 to 1:1 million. The Catalogue also
offers a SW tool, fully multilingual, for creation
and-or editing metadata records (Metadata
Editor).

OneGeology
The national geological map data, maintained
and provided by 21 national geological survey
organizations, are presented in this Metadata
Catalogue in a form of datasets, dataset series
or where available as on-line services.

OneGeology
In order to harmonise descriptions of national
geological and applied geological maps or
map series a new Geological Metadata Profile
(GMP) was developed and utilised when
collecting the metadata records. The GMP is
fully based on the EN ISO 19115 (for datasets,
series) and EN ISO 19119 (for services)
international standards. The GMP is also
compliant with the INSPIRE Metadata
Regulation (Nr. 1205/2008).

OneGeology
In order to directly display a metadata record
(geological or applied geological map) for
which an on-line map service is available, the
Metadata Catalogue is integrated into the
OneGeology-Europe Portal. Both the
OneGeology-Europe Portal and the Metadata
Catalogue build together a unique multilingual
system for discovery, view and use of
geological data across Europe

Metadata profile design
1. Designing Plan4all metadata profile
Mapping to ISO 19115 / 19119 / 19139
Mapping to INSPIRE metadata profile
Detecting specific plan4all elements – extensions ?
Detecting specific queryables
2. Creating testing catalogue on Plan4all portal
