Linking RECORD to other international platforms is now a compelling issue. As the models follow a given standard, they can be placed in a repository and used by other researchers. The option to use web interfaces enables application by non-scientist end-users. Examples are given showing the ability to recode simple models, encapsulate more complex models, link with GIS and databases, and use the R statistical package to run models and analyse simulation outputs. A variety of research projects already use this platform. A graphic user interface was designed to simplify coding tasks. difference equations, differential equations, state charts.). It integrates different time steps and spatial scales and proposes some standard formalisms used to model agro-ecosystems (e.g. After testing several existing environments, the RECORD platform was developed under the VLE environment, allowing the design of atomic and coupled models. French researchers involved in such design issues developed a specific modelling platform to help model, simulate and evaluate cropping systems.

Modelling complements field experiments in the design of new farming systems. A case study depicts how the requirement document is processed.ĭue to significant changes in agro-ecological contexts, farmers need new solutions to produce goods. All of the information required for both request generation and response validation is taken from the original service requirement specification. The test script is also used to validate the responses. From the test case table a test script is generated and from that test requests are produced. On the other hand a test case table is generated for executing those functions. On the one hand, a requirement table is generated from the text to compare with the functions offered. Our goal is to join requirement specification with test specification in one document which is used to both specify what the user requires from a service and to test if a particular service is providing it.

what operations to invoke in what order, but also how to test, i.e. The test cases define not only what to test, i.e. The advantage of this type of document is that it can be automatically analyzed in order to extract test cases for testing the web service. The following paper proposes a structured, natural language specification of web service behavior based on keywords in context.
