Introduction
Spatial data infrastructure (SDI) is a general term for the computerised environment for handling data that
relates to a position on or near the surface of the earth. It may be defined in a range of ways, in different
circumstances, from the local up to the global level.
This Technical Report focuses on the technical aspects of SDIs, thereby limiting the term SDI to mean an
implementation neutral technological infrastructure for geospatial data and services, based upon standards
and specifications. It does not consider an SDI as a carefully designed and dedicated information system;
rather, it is viewed as a collaborative framework of disparate information systems that contain resources that
stakeholders desire to share. The common denominator of SDI resources, which can be data or services, is
their spatial nature. It is understood that the framework is in constant evolution, and that therefore the
requirements for standards and specifications supporting SDI implementations evolve continuously.
SDIs are becoming more and more linked and integrated with systems developed in the context of e-
Government. Important drivers for this evolution are the Digital Agenda for Europe, and related policies. This
Technical Report takes these developments into account. By sharing emerging requirements at an early stage
with the standardization bodies, users of SDIs can help influence the revision of existing or the conception of
new standards.
The users of an SDI are considered to be those individuals or organisations that, in the context of their
business processes, need to share and access geo-resources in a meaningful and sustainable way. Based on
platform- and vendor-neutral standards and specifications, an SDI aims at assisting organisations and
individuals in publishing, finding, delivering, and eventually, using geographic information and services over
the internet across borders of information communities in a more cost-effective manner.
Considering the complexity of the subject and the need to capture and formalize different conceptual and
modelling views, CEN/TR 15449 is comprised of multiple parts:
• Part 1: Reference model: this provides a general context model for the other Parts, applying general IT
architecture standards;
• Part 2: Best practices: this provides best practices guidance for implementing SDI, through the evaluation
of the projects in the frame of the European Union funding programmes;
• Part 3: Data centric view: this addresses concerns related to the data, which includes application schemas
and metadata;
• Part 4: Service centric view (in preparation): this includes the taxonomy of services, concepts of
interoperability, service architecture, service catalogue, and the underlying IT standards.
Further parts may be created in the future.

1 Scope
This part of the Technical Report provides best practices regarding Spatial Data Infrastructures (SDIs),
referencing to the outcomes of the projects in the frame of the European Union funding programmes. It
summarises the deliverables of projects, structured according to the reference model defined in Part 1 of this
Technical Report, to be made available in an on-line repository where the relevant outcomes are collected and
classified in order to provide a structured sets of recommendations for implementing SDIs at the European,
national and sub-national levels.
This collection refers mainly to the projects funded by the European Union funding programmes: this choice is
driven by the wide vision and analysis which such kind of projects can provide and the wide numbers of
stakeholders which have been involved.
The outcomes delivered by these relevant practices are collected into a document registry available through
the CEN/TC 287 web site. This part of the Technical Report defines the processes and the content of these
projects and documents registries, which will help making them more accessible and re-usable. It provides the
relevant project deliverables addressing the main SDI issues as described in the other parts of this Technical
Report.
The intended readership of this Technical Report are those people who are responsible for creating
frameworks for SDI, experts contributing to INSPIRE, experts in information and communication technologies
and e-government that need to familiarize themselves with geographic information and SDI concepts, and
standards developers and writers.

5 Overview
5.1 Introduction
This clause describes the various roles that projects can assume in relation to the standardisation processes.
It will describe the categories of contributions that projects give, directly or indirectly, to standards
development, evaluation, support to the implementation, and education of standards for geographic

information. In addition there are projects that help linking standards development to the implementation of
legal acts and policies.
In particular for the outcomes and best practices of projects that are not directly involved in the standards
development processes, it is paramount that their efforts be captured and made sustainable beyond the
lifetime of the projects.
1) 2) 3)
With INSPIRE , GEOSS and GMES now well established, numerous projects and activities that are
(co-)funded by EU programmes are being asked to use or build upon standards and specifications in the
domain of geographic information. Design methodologies, reference models, good practices in UML data
model design and data model transformation, as well as standards for various services are examples of topics
that are being or that have been addressed by dozens of European Union-funded projects. The paymasters
and the consortia that developed these products have made investments that should be protected.
4)
The GIGAS project (GEOSS, INSPIRE and GMES, an Action in Support), financed by the Directorate
General Information Society of the European Commission, has made concrete recommendations on how this
could be done. In particular, a role is proposed for CEN/TC 287 Geographic Information to maintain relevant
deliverables or parts thereof, not only of the GIGAS project, but also of other EU-funded projects. This is to
lead to a formal EU-level repository of reference material on interoperability, where future projects can find
state-of-the-art information on interoperability. At the same token, these projects could then add new
reference material as they progress in their work programmes.
This part of the Technical Report, along with the CEN/TC 287 document registry, constitutes the backbone for
making the outcomes and best practices of projects sustainable.
5.2 Categories of contribution
5.2.1 Content classification
The general issue is knowledge management related to standardization processes in projects funded by the
European Union programmes. More specifically, the proposed relevant practices should support the analysis
of project outcomes, which in the majority of the case are documents, but it can be also IT tools, infrastructure
and datasets. The core goal of this repository is strictly limited in the setup of a document registry related to
the relevant outcomes of European Union funded projects. Additional extension of this registry to manage
references to outcomes different from the documents will be taken into account in the future release.
The content managed by this registry can be categorized according to different aspects, applying a faceted
classification. A faceted classification allows the assignments of multiple classifications to a document,
enabling the classifications to be ordered in multiple ways, rather than in a single, predetermined order. A
facet comprises “clearly defined, mutually exclusive, and collectively exhaustive aspects, properties or
characteristics of a class or specific subject. According to this concept, the outcomes of projects related to SDI
can be categorized according to different facets which are listed below. According to this approach, each
document register will be classified under these different facets and the implemented registry permits to
address the registers according to this combined facets. The collected documents registers refers to best
practices about implementing SDI.
The following subsections provide the classification of the project outcomes in terms of the reference model
components, architectural reference services, and the phase(s) of an SDI, to which a project outcome is
applicable.
1) Infrastructure for Spatial Information in the European Community (INSPIRE), http://inspire.jrc.ec.europa.eu.
2) Global Earth Observation System of Systems, http://earthobservations.org/ .
3) Global Monitoring for Environment and Sustainability, http:///www.gmes.info .

5.2.2 SDI reference model components
A project outcome addresses one or more of the following SDI components:
• Data;
• Register;
• Discovery;
• View;
• Invoke;
• Download;
• GeoRM;
• Orchestration and Composition.
5.2.3 Architectural reference model services
A project outcome is characterized by one or more of the following type of services:
• Human Interaction Services;
• Model Management Services;
• Workflow/Task Services;
• System Management Services;
• Processing Services;
• Communication Services.
5.2.4 Phases of an SDI
A project outcome can focus mainly on one of the following different phases related to the SDI implementation
process:
Concept and design: including analyses, methodologies, reference models, state of play related to the
main SDI areas;
Implementation: including development methodologies, development implementation, deployment,
management and maintenance;
Validation: including monitoring, testing and reference standards compliance.
5.2.5 Project document types
Given the current way of delivering project results by submitting documents, this overarching goal implies
taking documents pertinent to the issue required to implement an SDI, and in particular:
1) Standards: the reference standards analysis, applicability, implementation, testing, refinements and
validation. This information must be applied.
9
---------------------- Page: 11 ----------------------
SIST-TP CEN/TR 15449-2:2013
CEN/TR 15449-2:2012 (E)
2) Specifications: related to the standards or legally binding documents containing detailed description
of the requirements, recommendations and where relevant open issues. Specifications provide more
flexible level of documentation supporting more fixed binding documents. Specifications usually
remain on more conceptual level of reality abstraction.
3) Technical reports: often representing overall or partial outputs of the projects. Technical reports
often stands on more logical level of reality abstraction.
4) Guidelines: the technical documentation and guidelines related to the issues described above.
Guidelines can contain practical examples, best practices of the specific SDI components
implementations.
5) Software tool: the software component (either OSS than COTS tools) including products, API,
development environment, etc.
6 Processes and procedures
6.1 Requirements from a content provider perspective
This clause defines the processes and procedures for the inclusion and update of the outcomes and best
practices of projects. These processes and procedures has been determined by the analysis of the registry
requirements according to a project perspective.
From a project perspective, it is expected to have a simple system to populate and to upload the register
related to the best practice document. This entails:
a) being able to register the project through a wizard approach: a step-by-step process where the best
practice provider enters:
1) project details,
2) executive abstract,
3) contact details, etc.,
4) link to other "persistent" Web 2.0-like information available (e.g. YouTube channel, etc.),
5) PR material (official brochure / flyer as PDF),
6) link to official website,
7) project duration,
8) gantt chart and deliverables (incl. delivery dates),
9) other (e.g. funding programme),
At any time the document provider should be able to "save" and continue later, and should see the
remaining information needed to complete the process.
b) when uploading information minimise re-structuring of deliverables which would be time consuming and
discouraging;
c) ideally the document provider would like to upload a series of pdfs and tag them through a pre-defined
structure. An option could be to have online forms where to copy and paste (with all the problems this
may cause) the various sections of the deliverable (like Wikipedia but it should be much more usable);

d) have facilities to access the software code by the provision of a URL or software code page or repository.
6.2 Inclusion of projects in this part Technical Report
6.2.1 Permanent call for contributions
The contributions collected and referred to in this technical report are related to the date of publication of this
version of document. However, the collection of the best practice documents related to the outcomes of the
European Union funded projects will continue and a permanent call for contribution will be maintained and
open by the CEN/TC 287 secretariat. The upcoming requests for inclusion in the registry of new best practices
references will be processed according to the procedure defined in the following paragraph, and they will be
stored into the online registry managed by the CEN/TC 287 secretariat. It will be evaluated when it will be
opportune to publish an updated version of this part of this technical report, including the updated reference
documents and best practices collected into the on-line registry.
6.2.2 Role definitions
Regarding item registration in general, EN ISO 19135 identifies six diverse roles:
Register Owner: an organization establishing the register and has the primary responsibility for the
management, dissemination and intellectual content of the register.
Register Manager: manages the register(s) of items.
Submitting Organizations: a qualified organization to propose changes to the content of a register, or
an appeal if the proposals are not accepted.
Control Body: a group of technical / thematic domain experts deciding on the acceptability of the
proposals and changes to the content of a register. The control body shall accept proposals from the
register manager and renders a decision regarding each proposal.
Registry Manager: a person or an organization responsible for the day-to-day management of a registry
(an information system on which a register is maintained). The registry manager ensures the integrity of
any register held in the registry and provides means of electronic access to the registry for register
managers, control body(ies) and register users.
Register Users: access a registry in order to use one or more of the registers. They may includ
