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

Chapter 3 of the “Metadata v2 Specifications”

32

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

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
