Harmonisation of data and metadata models. metadata point of view

1. Harmonization of data and Metadata models.
Metadata’s point of view
Jean Christophe Desconnets
IRD - ESPACE

2. Where are the critical points to discuss ?
INSPIRE Implementing Rules for metadata (table 1)
Metadata for all themes (table 2)
Specific metadata for
biogeographical regions (table 4)
Specific metadata for
Habitats & Biotopes (table 5)
Specific metadata for
Species Distribution (table 6)
Specific metadata for
protected Sites (table 3)
profile for Protected Sites profile for Bio-geographical
regions
profile for Habitats &
Biotopes
profile for Species
Distribution
profile for Spatial services
Composition of metadata profiles for the NatureSDI+ project
Lineage Information
Species information

3. Where are the critical points to discuss ?
 Bio geographical zones
Metadata specific to the Biogeographical Regions theme
Metadata element Multiplicity Condition
Mandatory and conditional metadata elements
Field Survey information 1..*
Specific data quality information 1
Optional metadata elements
Thematic Data Information 0..*
Detailed Lineage
Information
Question 1 : are we need this level of detail on lineage of dataset ?
Question 2 : are we need informations about the method of observations ?

Harmonization of terminology
Condition of description on metadata
(dataset contains one or more than one
species distribution)
What about “species” data type in data
model ?
