1 Tim Richards & WP3 Partners NEFIS Project Meeting WP3 Summary 28 – 30 June 2005, Ispra

2 Work Package 3 Activities & Deliverables NEFIS Technology Reviews Standards in the GI Sector Web Services & NEFIS – parts I & II NEFIS Big Picture Architectural Design – UML Design Report (D9) NEFIS Knowledgebase on Forest Information Systems KB Demonstrator (D2) EFIS-RD Updated EFIS Resource Discovery System (D2b)

3 Technology Review 1 - Standards in the GI Sector Open GIS Consortium Abstract specifications Implementation specifications Geospatial Metadata: ISO Series Content Standard for Digital Geospatial Metadata (FGDC) The OpenGIS Abstract Specification; Topic11: Metadata (OGC) Geospatial Data & Services Global Spatial Data Infrastructure - GSDI Infrastructure for Spatial Information in Europe - INSPIRE European Position

4 Technology Review 2 - Web Services & NEFIS Web Enabling Technologies Metadata XML – as an enabling syntax Web Services: UDDI – resource discovery WSDL – resource / service description SOAP – data object packaging Semantic Web – Ontological Languages

5 Technology Review 2 - Web Services & NEFIS Conclusions – re cataloguing Continue using DC Use XML Use WS – not inconsistent with DC Remain flexible Conclusions – re ddb functionality – 3 options CORBA Federated Web Services (XML, SOAP, WSDL) Semantic Web

6 NEFIS Knowledgebase (KB) The purpose of the KB is to provide an on-line repository for information on forest information systems, including: outputs from NEFIS activities freely available documentation on forest information systems/services development initiatives (e.g. Global Forest Information Service – GFIS; European Forest Information Service – EFIS, National Forest Information System – NFIS) and other relevant projects relevant software resources, tools, reports and documents A metadata catalogue of information resources – defined by its collection policy – i.e. Forest information systems & related knowledge

7 NEFIS Knowledgebase

8 Q. What is the NEFIS Metadata Standard? fi

9 Architectural Design – UML (Cf. Presentation on Wednesday)

10 EFIS Information Resource Discovery System EFIS-RD Activities : Updated to use mySQL database Updated to use the NEFIS metadata elements, including the EEA spatial reference system profile Updated to use the NEFIS keywords for data entry and browsing Updated to demonstrate a simple distributed forest area by administrative unit information service, including linkage to the VTK

11 EFIS Resource Discovery System System enables: Metadata entry Metadata searching Metadata editing Browsing by keyword Distributed data extraction demo

12 EFIS Information Resource Discovery System Distributed Search Implemented using XML-RPC Enables: query of distributed information services – by country extraction of sub-national forest area data packaging of data into XML communication of XML data across HTTP connection collation of data into one aggregate result set visualisation of collated data in the VTK Constitutes a simple web service. [NB, a fully featured web- service would more likely use UDDI, WSDL and SOAP]

13 EFIS-RD Data Collection / Collation Demo – sub-national forest area statistics Java XML-RPC servers provide national information services, data is packaged into XML for transport over HTTP, a multi-threaded XML-RPC client in the EFIS-RD system receives data from each server, collates it, presents it in a table and lastly prepares it for use in the VTK. ServersClient * 1 Standardised Data...or Standardisation Toolkit

14 WP3 Summary Standards & Technology Web Services (UDDI, WSDL, SOAP, etc) GI standards Project Activities NEFIS Knowledgebase Proposal for a Forest Markup Language Architectural Design / UML EFIS-Resource Discovery - Metadata EFIS-RD distributed data extraction and collation (XML- RPC) Adds up to a coherent work package
