CDDA data model sub-set

Identified tables and attributes for mapping with INSPIRE PS Simple application schema


INSPIRE PS DM


STEP 1: Analysing CDDAUnique identifierDesignation of a site Relationship to legal basis (law)

Relationship between graphics and alphanumeric informationINSPIRE PS Simple application scheme extensions

CDDA – INSPIRE PS Simple application schema Matching Tableconverting CDDA data into GML format and file sizeVoidable – properties with no data in INSPIRE


INSPIRE PS

Easy mappingComplex mapping requires additional thematic and discussions


STEP 2: Conceptual MappingTarget DM: INSPIRE PS simple

Matching Table Rules for EncodingTraitment of Voidable elements

Class Definition Stereotype INSPIRE Theme

ProtectedSite An area designated or managed w ithin a framew ork of international, Community and Member States' legislation to achieve specif ic conservation objectives.

feature type Protected Sites

Attributeschema

geometry The geometry defining the boundary of the Protected Site.

1 GM_Object

id this attribute is required for proper validation scheme

External object identif ier of the protected site. 1 Identifier

localId A local identif ier, assigned by the data provider. The local identifier is unique w ithin the namespace, that is no other spatial object carries the same unique indentif ier

namespace Namespace uniquely identifying the data source of the spatial object

legalFoundationDate The date that the protected site w as legally created. This is the date that the real w orld object w as created, not the date that its representation in an information system w as created.

1 DateTime

A URL or text citation referencing the legal act that created the Protected Site.
