Objectives

  • Collect Japanese terms and meanings used in

p g Japanese agricultural application programs for farmers and define the standard terms and farmers, and define the standard terms and meanings (similar to FAO AGROVOC Concept S ) Server)

  • Define XML schema using standard terms to

e e sc e a us g s a da d e s o exchange data D fi i t f t i lt l d t

  • Define an interface to access agricultural data

for farming

Java like naming

  • MetBroker (Meteorological Data Virtual

( g Integration System) written in Java. We use net agmodel MetBroker name space for net.agmodel.MetBroker name space for MetBroker Objects

  • id.ac.ipb.MetBroker is another name space.

System A System B Standard ・・・ Term A.a Term B.b

  • 1. Collecting Term

S ti Term API.c If and only if A.a = B.b, define 1. 1. 2. 6 . Query using each term Semantic MediaWiki Term API.c A.aand B.b are synonyms of API.c API

  • 3. Define API using the namespace “API”
