1 AGRIS AP Guidelines for Information Object Description

2 AGRIS AP Definition An application profile is a type of metadata schema which consists of data elements drawn from one or more namespaces, combined together for a particular application

3 AGRIS AP What s AGRIS AP A Metadata Standard Common format 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

4 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

5 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

6 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

7 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

8 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

9 AGRIS AP Usefulness and Availability Items to be Excluded: short-lived information restricted or confidential material news on local events textbooks for secondary education non-original or repetitive material legislation on local subjects of short duration

10 AGRIS AP Usefulness and Availability Items to be Included: Preprints of important articles a very short article on original taxonomic description a case study in veterinary medicine obituaries of outstanding scholars editorials, letters to editors or material which appears in regular columns

11 AGRIS AP Usefulness and Availability Also include: bibliographic units without creators (anonymous) opening speeches in meetings, conferences. Etc literature produced for the extension worker

12 AGRIS AP Essential Definitions Element: a unit of data or metadata Element Refinement: An element qualifier makes the meaning of an element either narrower or more specific Encoding Scheme: may either be controlled vocabularies or formal notations
