Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
The advancement of telecommunication and database technologies has helped the introduction of new
types of services such as indoor navigation and multimodal navigation deployed on rapidly proliferating
mobile devices such as smartphones. These newly emerging services may require geospatial databases
that contain diverse and detailed content beyond the map databases used in current car navigations
systems. A new database service framework that enables the usage and sharing of geospatial databases
can facilitate emerging ITS applications and services.
This document addresses a database service framework and the components of the framework based
on a federated database architecture commonly adopted to resolve heterogeneousness between
databases. The purpose of the ISO 19297 series of standards is to promote the interoperability of
geospatial databases for both suppliers and user environments, to enable the usage and sharing of
geospatial databases and to facilitate ITS applications that satisfy market needs.
The ISO 19297 series of standards is a two-part standard. The following is a brief description of the parts.
— Part 1: Framework
ISO 19297-1 describes the concept, architecture and characteristics of the shareable geospatial
database framework and use cases. It provides an introduction to the standard series and identifies
key components of the framework, which will be developed as separate standards.
— Part 4: Common data structure
1)
ISO 19297-4 explains a common data structure for data delivery. A common data structure
transports query results to information mediators or user applications. Thus, data sources coming
from heterogeneous geospatial databases become homogenous to information mediators or user
applications.

5 Shareable geospatial database framework
5.1 Concept
A shareable geospatial database framework should allow diverse ITS applications to access, query,
process, and download various types of geospatial data content stored in separated databases in a
simple and unified way. The framework originates from a wrapper and information mediator-based
architecture where a pool of participating geospatial databases operated by individual organizations or
enterprises form a virtually integrated database, and the architecture makes these coupled databases
easily accessible over the internet.

5.2 Architecture of the shareable geospatial database framework
5.2.1 Tier 1
The shareable geospatial database framework consists of four tiers (Figure 1). Tier 1 represents a pool
of service centres operated by map providers, mobile network operators, private companies, central
or local governments, and even commercial buildings (e.g. department stores) participating in the
federated database architecture. These service centres have full autonomy in their operations and
great diversity of geospatial data content.
5.2.2 Tier 2
Tier 2 denotes wrappers. A wrapper is a software component that establishes the communication and
the data flow between information mediators and data sources. Access and querying of databases by
users is transparent regardless of the database type due to the standardized interfaces of wrappers.
Wrappers are usually closely coupled with the service centre databases.
5.2.3 Tier 3
Tier 3, information mediators, exist between wrappers and user application tiers. An information
mediator is a software module that exploits encoded knowledge about certain sets or subsets of data to
[6]
create information for a higher layer of applications . An information mediator offers two important
functions: information reconciliation and information brokerage. Information reconciliation refers to
the actions of translation, distribution, and dispatching user requests to acquire proper query results.
The information brokerage function covers a series of processes so that user applications are able to get
information about services, feature catalogues, and metadata.
The mediator-wrapper architecture effectively resolves database heterogeneity and greatly lessens the
burdens of building a huge integrated centralized geospatial data store.
