In order to prepare the Commission proposals, an international team of experts has been working since October 2005 to review available reference material and international standards to create a set of prime reference documents that will govern the development of the draft IR for data specifications:
– DS-D2.3 Definition and scoping of the Annex themes;
– DS-D2.5 Generic Conceptual Model;
– DS-D2.6 Methodology for the development of data specifications;
– DS-D2.7 Guidelines for the encoding of spatial data.

This document, DS-D2.6 Methodology to develop the data specifications is therefore not a draft IR, but a document that, together with user requirements and the other documents mentioned above, is targeted to help in the process of developing the IR for data specifications.

In particular, this document specifies how individual INSPIRE spatial data themes have to be modelled based on the user requirements, the INSPIRE Generic Conceptual Model (DS-D2.5) and the relevant international and industrial standards.

DS-D2.6 will be used by the Thematic Working Groups as described in the INSPIRE Work Programme Transposition Phase 2007-2009 and in the Terms of Reference of the actors involved in the data specification process. The result of applying DS-D2.6 will be the data product specifications, prepared according to ISO 19131:2007 Geographic information - Data product specifications, for the individual themes, i.e. conceptual information models that describe the relevant classes, their attributes,
relationships and constraints, as well as other information as appropriate like data capturing information or data quality requirements.

It does not create direct obligations to the Member States.

p.s.

Il documento INSPIRE Data Specifications - Methodology for the development of data specifications contiene varie indicazioni su “come” realizzare le specifiche dei dati previsti.
Tra queste:

Requirement 16:
The INSPIRE data specifications shall conform with ISO 19131 (Data Product Specification).

(il 19131 è stato pubblicato come standard ISO quest’anno)

Si tratta di una modalità per definire le “specifiche di un prodotto”, sia esso un dataset oppure una serie di dataset, con una serie di informazioni utili per chi deve acquisire, distribuire oppure utilizzare il prodotto in questione.
E’ molto interessante, perchè ricorda lo scopo delle specifiche IntesaGIS sui dbTopografici.

Ecco un esempio concreto (estratto Annex F della versione Final Draft dello standard ISO19131 ).

Cosa prevede il 19131
Il 19131 prevede che un prodotto sia descritto indicando questi elementi:

  • Overview
  • Specification scopes
  • Data product identification
  • Data content and structure (con modello UML delle classi + descrizione del feature catalogue) >> il contenuto di questa sezione può considerarsi simile al contenuto di 1n1007 di IntesaGIS
  • Reference systems
  • Data quality
  • Data product delivery
  • Metadata

e opzionalmente, informazioni su:

  • Data capture
  • Data maintenance
  • Portrayal
  • Additional information
