For the description, Exchange and retrieval of Agricultural information Resources
Based on:o Dublin Core Elements (DCMES)o Agricultural Metadata Element Set (AgMES)o Australian Gov. Locator Service Metadata Set
AGRIS AP Methodology
Development of a conceptual map of the different types of information resources used in the AGRIS
Evaluation of standards and common resource description practices
AGRIS AP Goals and Objectives
To facilitate interoperability of metadata formats
To facilitate harvesting of data from members
Linking of various types of information
Cross searching facility
AGRIS AP Goals and Objectives
Common search interface for heterogeneous archives, i. e. the AGRIS Multi-host Server
Harvesting of Metadata from other sources
Sharing experience between applications and Standards
AGRIS AP
Methodology Development of a conceptual map of
the different types of information resources used in AGRIS and amend it
Evaluation of standards and common resource description practices
Mapping of currently used elements to the available element pool
studying of implementation results and problems for further enhancements and/or amendments
AGRIS AP
What are the Resources Resources covered by the AGRIS
centres over time are often unavailable nowadays
Electronic publishing is the only gateway to accessibility
These are the unique resources which the AGRIS resource centres can offer
Criteria of Resource selection/ Collection development
