  2. Agenda • Review Initial Draft of API • Tools and Libraries • Maven Overview • Code Conventions • How to Get Started

  3. API Overview • Establishes the foundation for the development effort by providing a contract for what a subsystem must provide functionally. • Validators – provide information on the validity of an incoming document. More than one validator may be used on a specified document. • Translators – convert a document from one input document format to an output format. More than one translator may be used to perform the conversion. • Handlers – assemble the validators and translators to best handle a specified input document.

  8. Tools and Libraries • Libraries • Spring • http://www.springsource.com/developer/spring“Spring is a popular and widely deployed open source framework that helps developers build high quality applications faster. Spring provides a consistent programming and configuration model that is well understood and used by millions of developers worldwide.“ – from springsource.com • Maven • http://maven.apache.org“Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.” – from apache.org • Saxon • http://saxon.sourceforge.netThe Saxon package is a collection of tools for processing XML documents. The main components are: an XSLT 1.0/2.0 processor, an XPath 2.0 processor, an XQuery 1.0 processor, and an XML Schema 1.0 processor. • Schematron • http://www.schematron.com“A language for making assertions about the presence or absence of patterns in XML documents.” – from schematron.com

  9. Tools and Libraries cont. • Tools • Open Health Tools • http://www.openhealthtools.org • Provides a source code repository • Provides document repository • Provides wiki forum • Provides discussion forum

  10. Maven Overview • Typical Project • Pom.xml – specifies the project structure, dependent libraries, reports, unit-testing, etc. • Src • Main – contains the deliverable code • Java • Config • Resources • Test – contains the code that tests the deliverable code • Java • Config • Resources • Target – the destination for all compiled code, reports, etc. • Site – contains the generated reports (checkstyle, cobertura, javadoc, etc) • $USER_HOME\.m2 • Settings.xml • Repository – contains the dependent libraries

  11. Maven Overview cont. • Sample commands • mvn install – sets up project locally by downloading dependent libraries, etc. • mvn clean – cleans all target items • mvn test – tests the code • mvn site – generate all reports for the project • Plugins • M2Eclipse – http://m2eclipse.sonatype.org • NetBeans – http://wiki.netbeans.org/MavenBestPractices • IntelliJ – http://www.jetbrains.com/idea/features/ant_maven.html See http://maven.apache.org for detailed reference, samples, quickstart, etc.

  12. Development Conventions & Process • Package structure • gov.hhs.hin.ri.toc • gov.hhs.hin.ri.toc.contract– contains the API (e.g., DocumentHandler, DocumentTranslator, etc.) • gov.hhs.hin.ri.toc.handlers – contains the handler implementations (e.g., GenericDocumentHandler) • gov.hhs.hin.ri.toc.translators– contains the translator implementations (e.g., XslTranslator) • gov.hhs.hin.ri.toc.validators– contains the validator implementations (e.g., SchematronValidator) • Process • http://wiki.siframework.org/S%26I+Framework+RI+Development+Process

  13. How to Get Started • Please provide feedback and suggestions on development plan and API by 7/7/2011. • Create a login account at www.openhealthtools.org. • Install Maven 3.0 and review documentation. • Install IDE (Eclipse, NetBeans, etc.) if desired. • Suggested Review • Spring • http://blog.springsource.com/category/green-beans/ • Suggest Getting Started with Spring Integration • Saxon • http://www.saxonica.com/documentation/about/gettingstarted/gettingstartedjava.xml • Schematron • http://www.schematron.com/elements.html • Tasks assignments are scheduled to begin 7/12/2011.
