Three (Main) Requirements
21
Why New Metadata Specifications?• When producing a dataset and its metadata, a data
provider is required to follow some rules about the information layout…
• These rules help us to process (parse and syntactically check) these data and metadata files automatically
• To overcome the limitations (incomplete, lack of explicitness, not always used…) of the existing Metadata Specifications
22
Why New Metadata Specifications?• Create a “legal” reference frame for data exchange
• Explain each detail of data/metadata structures for data providers
• Prepare a solid basis for the creation of automatic database integration tools
• Create a public and official interface for data exchange for any interested party
23
Evolution of the Specifications• The core is the same as before, with
several evolutions:• Compatibility with INSPIRE Directive
has been reached• New fields and properties have
been added• to describe more precisely data• to improve automatic checking
24
Evolution of the SpecificationsThe New Specifications cover:
• the rules for data layout• the rules for metadata layout• the rules for statistical units integration (new!)
They hold in a 150 page document…… Available also in HTML
25
New Model: a Brief Introduction• The Abstract Metadata Model is very simple
• It is almost the same as before, except:• Many elements have new fixed names• A new element Spatial Binding
• to ensure compatibility with INSPIRE• to check the spatial references
26
New Model: a Brief Introduction• Each element or property described by
the Specifications is now represented homogeneously

Some Metadata Shortcomings
Missing Keywords
The 0/1 Theme Problematic
No Precise Codification for Indicators Names
No Precise Indication for Units of Measure
No Full INSPIRE Compliance
33
New Metadata Specifications…
Consequences• Metadata v1 Editor is now
disabled…• We will upgrade the existing
metadata to comply with the new specifications
From now on…• Please, use our Excel temporary
Solution
…Until June 2012• Metadata v2 Editor Delivery
1. INSPIRE Compliance
2. Integration of New Geographical Objects
3. User Friendliness
Three (Main) Requirements

35
ESPON Data Base SchemaNeeds to be Updated
• To store the New Metadata
Needs to be Extended• To store New Geographical Objects
and Nomenclatures• WUTS (World NUTS 0)• Urban Objects (UMZ, FUA…)

Work Done since June 2011
• A Critical Analysis of the ESPON DB v1• Lessons Learned and Experience from
the Phase 1• Remarks of the ESPON CU
• Metadata Specifications
• Nomenclature Integration Specifications
• Database Schema upgrade
51
Interface Updates (Dec. 2011) Overview of indicators
52
Interface Updates (Dec. 2011) Disabled
• Metadata Editor v1… replaced temporarily by an Excel file compliant with the Metadata Specifications reference document… before the delivery of the Metadata Editor v2
• Not so useful search criteria• Selection by geographical objects (only
NUTS)• Selection by publication date
