Vital Signs Todo This is a test

Common RoadblocksDevelopers on the forums and via e-mail asked common questions:How do I ?Quite a bit of questions about how to represent a particular CDA template using EverestI have a jurisdiction that does X differently than the standard, how do I represent this?Lots of common questions were asked about how to represent jurisdictional constraints in EverestSome common themesJurisdiction has a custom schema for their extended attributesJurisdiction has a custom series of elements represented in a word documentJurisdiction had computable representations and Java renderings but no C# equivalentEverest had some way to address this:Writing extended classes which implemented the templates/custom bitsWriting scaffolding codeWe wanted a more automated way to do this.

SherpasThe name:Everest was named after tallest mountain in the worldHL7v3 was considered by many to be equally difficult to implementThis toolkit would help developers climb that mountain = SherpasWhat is it?A template processor that binds CDA templates to Everest RMIM classesA series of helper classes that handle formatting/validation (as extensions to Everest)Sherpas GenerationOptimizerGPMRC#.DLLPOCD_MT000040UV.MIF XML) DCOR template RMIM structuresParse (XML => Model) DCOR RMIM structures based on templateIdTodo:More testing, esp. on parsingComplex template operations (splicing, combining, resolving based on xpath, etc.)Complex template constraints (expressed as XPath) Huge demand to generate templates from XSDSome demand to generate Sherpas templates from MDHT definitionsQuestions?
