To increase the code maintainability and the power of the validation of XML documents and messages, we chose to develop model-based validation services. Those services are available through the External Validation Service Front-end (aka EVSClient) of the Gazelle platform but you can also implement your own client to the web services of validation. All of them are built on the same model so you will only need to develop the client once and then "play" with the WSDL location.

Documentation

Below, we describe the methods offered by the web services and the expected parameters.

• about : Gives information about the called web service
• validateDocument : Validates an XML document using the given model-based validator
  • @param document : the XML document to be validated
  • @param validator : the name of the validator kind
  • @return : an XML based structure of the result of the validation
• validateBase64Document : Validates an XML document using the given model-based validator based on a B64 description of the document
  • @param base64Document : base64 encoded document
  • @param validator : the name of the validator kind
  • @return : an XML based structure of the result of the validation
• getListOfValidators : Returns the list of available validators
• @param descriminator: in some cases we may need to use the descriminator in order to select the validators to return (example : IHE, EPSOS, etc)
• @return : a list of string containing allowed validators' name

Web service client

We have develop a web service client for our proper needs to access these services. It's a Maven based project available in our Nexus repository. The latest release is available at http://gazelle.ihe.net/nexus/index.html#nexus-search;gav~~gazelle-ws-client*~~~
