Short about CEN/TC 287 WG5
Original terms of reference

• Check consistency of standards, and identify
  existing material required to implement Spatial
  Data Infrastructures, by drafting the Technical
  Report Standards, specifications, technical
  reports and guidelines, required to implement
  Spatial Data Infrastructures
• Ensure interoperability between national and
  European SDI developments by drafting the
  Technical Report Profiles and guidelines
  related to the use of standards for the
  implementation of interoperable spatial data
  infrastructures
• Identify what requirements are needed for
  interoperability conformance testing by drafting
  the Technical Report conformance testing for
  interoperability of components of Spatial Data
  Infrastructures

CEN/TC 287 WG5

• What type of spatial data infrastructure projects
  your organisation is currently involved with?
• Is it on national, regional or local level?
• Which CEN/TC287, ISO/TC211, OGC and/or W3W
  standards are used in that SDI project? (Please
  tick in the list of standards enclosed)
• Do you find a specification particularly useful
  for setting up a SDI?
• Are there any national standards you employ?
• Do you have specified a profile of standards for
  your SDI?
• What standards you think you will use in the near
  future?
• What standards you think are missing and should
  be created soon?
• What type of spatial data you are going to make
  accessible with your SDI.
• Any additional comments

Scope

• Spatial Data Infrastructure (SDI)
• metadata, spatial data sets and spatial data
  services network services and technologies
  agreements on sharing, access and use and
  coordination and monitoring mechanisms, processes
  and procedures, established, operated or made
  available in an interoperable manner.
• In this context the term SDI is restricted to a
  platform- and implementation-neutral
  technological infrastructure for geospatial data
  and services, based upon standards and
  specifications.

11
Scope

• This CEN Technical Report identifies the
  standards, technical specifications, technical
  reports and guidelines, required to implement a
  Spatial Data Infrastructure (SDI) in Europe.
• It gives recommendations as to whether any of
  these items should become EN, and proposes a
  roadmap for future work items.
• It further provides recommendations for measures
  to be taken in order to support implementation
  and maintenance of a SDI. In so doing, the report
  addresses a range of topics, including
  multi-lingual aspects, consistent identification
  of geographical items, conformance testing,
  geographic information metadata including
  catalogue service profile and guidelines, and WMS
  and WFS profiles and guidelines.

Reference Model for a SDI

• Based on GIRM
• Geospatial Interoperability Reference Model
• What is GIRM?
• The Geospatial Interoperability Reference Model
  (GIRM) references geospatial standards and
  specifications within a highly structured model,
  to help decision makers choose standards to
  facilitate interoperable geoprocessing

• Registries
• For the realisation of SDI in Europe, it is
  recommended to establish one or more registration
  authorities.
• A SDI needs, like any other distributed
  information system, a reference frame. A
  reference frame is the aggregation of the data
  needed by different components of the information
  systems. In a SDI context, the reference frame
  concerns
• the units of measures
• the coordinate reference systems
• the codelist definitions
• the feature data dictionaries (see ISO 19126)
• the feature catalogues (see ISO 19110)
• the portrayal catalogues and related symbology
  registers.
• Registries shall be established for the
  above-listed information elements and
  geographical items, and for
• Cultural and linguistic adaptability of metadata
  elements
• European common data models
• National data which are of interest in a cross
  border community or in a multilingual community.

• Data
• The model-driven approach is promoted for ESDI.
• Unique identifiers for use in a European SDI
  shall be composed of a namespace and a
  Universally Unique Identifier (UUID).
• ISO 19109 and referred standards are promoted as
  ESDI rules for specifying data structures and
  semantics.
• UML class diagrams used according to ISO/TS 19103
  is promoted as an ESDI conceptual schema
  language.
• ISO 19136 (GML) is promoted as the ESDI encoding
  method when transferring geographic data.
• ISO 19139 is promoted as the ESDI encoding method
  when transferring information related to
  geographic data such as metadata, feature
  catalogues, data dictionaries,

• Services
• This technical report recommends that all
  services be categorized according to the ISO
  19119 taxonomy.
• This technical report recommends applying the
  Web Service Architecture (WSA), including WSDL,
  SOAP, UDDI and XML when the following issues are
  considered to be important
• components of information systems run on
  different platforms
• the system consists of components from different
  vendors
• the service must be published and available on
  the internet
• wrapping of existing services where these are
  exposed as web services
• make existing services available for other
  applications on other platforms.
• It is inappropriate to apply WSA when dealing
  with large datasets.

• Conceptual Schema Languages
• This Technical Report encourages the use of UML.
• If an information community applies a Conceptual
  Schema Language other than UML, it is the
  responsibility of that information community to
  map the ISO general feature model to the
  meta-model of the Conceptual Schema Language of
  choice, and to maintain the mapping rules,
  following the ISO/TS 191032005 conformance
  statement
• Non-UML schemas shall be considered conformant if
  there is a well-defined mapping from a model in
  the source language into an equivalent model in
  UML and that this model in UML is conformant.
• In order to provide a GML application schema, an
  application schema shall be made by applying a
  conceptual schema language, and the GML
  application schema shall be derived from that
  conceptual model, applying the rules for mapping
  from UML as described in ISO 19136 in Annex E.

• Conformance testing
• It is recommended to establish a conformance
  authority charged with the conformance testing of
  implementations of SDI elements in Europe.
• Roadmap for new work
• It is recommended that CEN/TC 287, in
  collaboration with ISO/TC 211 and OGC, start new
  work on the following items
• catalogue server
• XML encoding of portrayal
• quality aspects of services
• standards for registries for geographical items,
  depending on the progress on ISO 19126
• Digital Rights Management
• the use of Web Services for dealing with large
  datasets.
