Global information needs

Increasing need for relevant up-to-date information on decision making dealing with forests

Countries with limited or slow access to latest scientific information on forests

Need to disseminate scientific information in these countries

Chapter 41, Agenda 21Intergovernmental Forum on Forests

Common vision for GFIS

Intergovernmental approachUser orientationFocus on countries with the greatest needs

• Specific target audiencesContent – wide rangeCatalogue approach

• no central collection of data

Use of Internet

WWW has affected the ways we workInformation access and exchangeFrom the global level to the localThe full impact on the way we work and on

society is still unknown

Advantages

Permanence of 24-hours per dayImmediacy of information discoveryContent diversityAccessibility from almost anywhereDe-centralised approaches allowing content

owners to maintain full rightsValue for money with low-cost solutions

General search engines

No more able to cover the whole netThe next generation of search tools will contain

more specialised and targeted services, More and more services will be provided to

registered clientsUser interfaces can be modified according to

personal requirements

Low search engine coverage

a Coverage with respect to the combined coverage of all engines; b Coverage with respect to the estimated size of the web.

Relative coverage. 1,050 queries used, 25–28 February 1999. These estimates are of relative coverage for real queries, which may differ from the number of pages actually indexed because of different indexing and retrieval techniques.

Providers compete for users

One user usually cannot effectively use but a few different services

Most services on the internet have been free, their funding is often based on advertising

Research information in forestry is often non-competetive

However, if the target audience is the general public the information producer enters the same competitive field as described above

GFIS NodesGFIS Information Server

• Coordinates the house-keeping functions of the GFIS node network

• Allows the user community to define content GFIS Node

The first contact point for those accessing GFIS will be the existing web-site of a GFIS partner or node. From there, the user will be able to search all participating metadata catalogues for desired

information. GFIS-affiliated node

Forest-related web-site that does not provide catalogue searching but which will be linked to the GFIS Information Server.

GISTbasedinformation serverhttp://gist.jrc.it/

What does GIST do?

GIST makes it easier to build an Information Server by providing the software components required for common tasks. In particular GIST provides facilities for:

submission of information by members of a user community modification and deletion of information presentation of information search and browse user registration and user interface configuration user authentication and authorisation automatic validation of user input server configuration and definition of policy rules

Source: http://gist.jrc.it/default/ Overview

GIST features

All the utilities and Web (CGI) applications can be run from the command line.

Small core set of applications to deal with the objects created:

• submission, alteration, and deletion of objects• facilities to search, show, lock and unlock objects.

Input translated from various formats including GET, POST, MIME (POST encoding) and XML

Object modellingGeographic searching, etc.

GIST Features

GIST installation

Platforms• AT compatible PC running a recent version of Linux

(GIST has been used on RedHat Linux versions 5.1 - 6.1)• Sun SPARC running SunOS 5.5.1 • Compaq Alpha running OSF1 (Digital Unix) 4.x

100MB free hard disk for the system, excluding data64MB RAM (128MB is better) and a network cardInstallation:

• install GIST software (Systems Administrator) • define and implement the data model (Database Admin.) • define and implement the user interface (HTML author)

HGS General characteristics

Geospatial search• Simplest case: bounding rectangle (Lat, Lon)

Temporal searching• Time range: start date, end date• Fuzzy: Before/After date

Text searching• Free text query

HGS Implementation

Clients discover databases through the directory structure

Clients can search selected databases

• Via a Web proxy server. Route searches to HGS servers.

• Directly through JAVA URLclass.

Clients can support ExplainURI’s

Independent Agents can be written in JAVA.

IUFRO Task Force

The mission of the Task Force is to develop a strategy and implementation for an Internet-based metadata system that provides co-ordinated world-wide access to forest information to assist meeting national and international efforts in achieving sustainable forests

Started in September 1998Volunteer based participants from international organisationsEU funded project for LAC countries with IUFRO SPCD

coordination and staff at FAO, Rome.

http://iufro.boku.ac.at/iufro/taskforce/hptfgfis.htm

The Intergovernmental Panel on Forests, 1997"Emphasised the need to review and improve information systems. Attention should be given to world-wide access to information systems that would encourage effective implementation of national forest programmes, increased private-sector investment, efficient development and transfer of appropriate technologies, and improved co-operation".

IUFRO, 1998

Established a Task Force ‘Global Forest Information Service’, with aim to

'develop an Internet-based service that will provide co-ordinated access to

forest information’.

International Consultation on Research and Information Systems in Forestry (ICRIS) , 1998Acknowledged the urgent need to improve access to information at all levels.

Recommended to endorse the development of GFIS.

The Vision“GFIS 5 years from now”

User The user should be able to easily find the information be able to evaluate

the quality and relevance of it for his/her purpose. The image

GFIS will be the 'one stop shop' for forest information on the globeInformation providers

GFIS will help the provider make their information more accessible to a broader audience with minimal effort

Finances

A group of donors have funded the establishment phase of the service. Progressively, as service becomes known the service may fund itself through advertisements, for example

DecentralisationThere are a number of geographically or thematically oriented ‘nodes’
