ELF Data Specifications


Why extending INSPIRE?

16 June, 2014

INSPIRE – too much – too littleINSPIRE is a huge investment for MS – butNot necessarily harmonised contentToo many options, no quality criteria,

no level of detail criteriaNo real cross‐border solutions

(„…where practicable…“Too many delivery methods,

not necessarily as a serviceNo rules on access conditions


Why ELF? European users needs!

Online access to up‐to‐date reference data from authoritative public authorities

Interoperable (Harmonised and Cross‐border) data content

Quality and metadata

Full coverage of Europe

Support common international standards

Management of national data through interoperable process

INSPIRE helps, but does not provide a solution

WP2 ELF Specifications

16 June, 2014

Master Regional/Global


Be clear about what NMCAs provide

• Requirements in data provision: LoD, MD, DQ• Move from national to European classifications

Seamless and consistent across borders

• Requirements in data provision: LoD• Associations

Consistent between themes

• Define core content• Use agreed classifications

Consistent between resolutions

• Requirements in data provision (update cycle, data quality)

Up‐to‐date, maintained and quality ensured

INSPIRE data model/schema status

Apr 2014: Approved INSPIRE data model r4618 and GML application schema files

Discrepancies between IR, data model and schema files

All Annex I themes: Codelist encoding changed from gml:CodeType to gml:ReferenceType

Missing GML application schemas handling placeholders and candidates (AU, SU, HY, LC, SR, TN)

INSPIRE application schema will be updated & published after MIG decision

Extended data models considered as draftUpdates of Annex I: overall process for xml schema maintenance in INSPIRE

are currently being discussed. INSPIRE MIG will use the revision process to better understand schema life‐cycle and release strategy requirements.

ELF data model/schema status Published ELF schemas

temporary solution due to availability of INSPIRE schemas Concern: current implementation leads to duplication of services

scale‐dependent application schemas

Take into account the different starting points and thematic scope for Master and Regional/Global level of detail

Be clear in the specification and data model what NMCAs can deliver at each level of detail in order to better accommodate the harmonisation of NMCA data, the development of Geo‐Tools as well as the ELF Services

To specify the product as detailed as possible in the UML (and GML) application schema to ease the reading of the data specification and enable automatic quality control to the largest possible extent

Result: a set of UML and GML application schema files for each level of detail Concern: increases the work for implementers as well as data publishers and users as

specific tools and software support are needed for each scale

16 June, 2014


Discussion

OptionA OptionB

INSPIRE/ELF model and schemas

To create INSPIRE GML application schema files from the latest INSPIRE UML application schemas and use as foundation for ELF UML and GML application schema files

To strictly use published INSPIRE UML and GML application schemas as the foundation for ELF

Data modelling approach

a set of UML and GML application schema files for each level of detail

A single scale‐independent UML model for all level of details

From isolated components to integrated, cross‐border seamless authoritative reference data …

Thank you!
