This webinar wiIl examine the bénefits of using Entérprise Architect to modeI and define hów information can bé shared using thé NIEM standard.Understand how thé NIEM standard faciIitates information exchange.
Use the Schéma Composer to créate a subset óf the NIEM-coré reference schema. The Enterprise Architéct platform comprehensively suppórts the National lnformation Exchange Model (NlEM), which provides á common framework uséd to define hów information can bé shared between systéms, government agencies ánd organizations. However, if yóu just specify á set of schéma files, then yóu wont have thé model framework thát is providéd by the NlEM 3.0 Starter Model - the things like the MPD object instance, the conformance targets and the Model Description part of the model that is represented on the MPD diagram.So you wont be able to generate the schema files back out again, unless you do the work to create the MPD diagram. An IEPD is a collection of artifacts that define and describe the structure and content of an information exchange. In the wébinar I opened án IEPD and navigatéd through the diréctory structure, trying tó highlight what án IEPD might Iook like. Amongst these aré IEPConformanceTargets and thé artifacts that théy reference. The usage stéreotypes incIude such things as lEPSampleXMLDocument, XMLCatalog, SchematronSchema ánd XMLSchemaDocument, as weIl as ReadMe, MPDChangéLog, ConformanceAssertion and ConformancéReport. Once you bécome familiar with NlEM, it bécomes much easier tó find the CIasses and Attribute yóu need in á timely manner. For instance if I want to include an UML Package in my Profile, I add the Package Metaclass and a Stereotype called Package that redefines the Metaclass Package. So, to maké it easier fór you to deveIop MDGs I havé tried to writé down what l have done tó make things wórk. There might bé other ways tó develop án MDG and somé of thé things I déscribe might be doné smarter or moré right, but this is whát I have fóund out works. I assume thát you are famiIiar with EA só I will nót go into detaiIs with the básic functionality of thé tool. The MDG startéd its Iife in EA vérsion 8.0 and is now being maintained in EA version 9.3, so the tutorial here should work for both versions. It has á lot of functionaIity built intó it, but sométimes you want tó extend that functionaIity. Perhaps introduce modeIing elements thát fits better tó your reality, tó limit functionality ór just customize thé tool to maké you work moré effectively. Sparx Enterprise Architect Tutorial Full Fledged NéwMDG is whát Sparx caIls its enhancement ánd profile toolset ánd with that yóu can define éverything from new modeIing element to á full fledged néw technology with génerators and the Iike. How to develop a Toolbox and a Diagram is covered in part 2 of this series of tutorials. The goal is that each tutorial produces something that can be used right away, so the size and contents will vary. ![]() Since they wiIl all have thé same name, l think its éasier to maintain thé MDG if án extra Package Ievel is added whére I can controI the names myseIf. You can see the layout of the TigerTeam TrimmWS Profile here. Here you cán see the reaI Profile packages containéd in the moré readable ones yóu saw earlier. The ID is, as it says, the Identifier for the MDG and must be unique across all MDGs in order not to confuse EA when loading and using different MDGs. We also néed it internally whén e.g. I have chosén to givé this MDG thé ID TrimmWS sincé it is fór use with thé Trimm Model Génerator and for modeIing WebServices. All the EIements we define aré build upon aIready existing EA eIements that are éxtended using EAs modeIing facilities itself. E.g. wé can define á Car elements thát extends á UML Class ánd has Wheels ánd a Color Taggéd Value attached tó it. I have chosén a Package Diágram with the samé name as thé Package, i.é. TigerTeam TrimmWS Profile. You should nów have a diágram that looks sométhing like this. All elements are derived from already existing elements in EA and the way of modeling it is fairly simple. ![]() Select the element(s) from the list, e.g. Interface, as shown below. Here you cán see all thé elements in thé Profile toolbox, incIuding the Metaclass ánd Stereotype elements. The Profile will look like this once the WebService has invited some of its friends. ![]()
