1 Quick Guide to CAM Blueprints
Intelligence Commanders Training Quick Guide to CAM Blueprints Using blueprints to develop XML exchange templates and schema Author: David RR Webber Chair OASIS CAM TC January, 2010 (CAM – Content Assembly Mechanism Specification) Foundations of Intelligence 1

2 Introduction Configuring formal information exchanges using XML transactions today requires a set of exchange schema that describe those interactions An exchange schema provides the structural layout for the XML transaction along with rules detailing the content expected Exchange schema development requires knowledge of XML best practices, industry specifications, data modelling techniques and guidelines for exchanging XML transactions How does the CAM blueprint approach enable a shift away from a purely manual process today to one that can be highly automated, consistent and repeatable? Introducing concepts and overall needs

3 Solution Approach Top Down development
Allows developers to quickly outline the information exchange Provides XML dictionaries of canonical reusable components CAM tool then expands the details and fill-in the blanks Review in visual editor to confirm or extend results Iterative approach until complete Automated exchange package generation Schemas, XML, documentation, mapping crosswalk Test generation of example XML with rules validation Principles and Rules evaluator Provides best practices for interoperability Checks for specific schema techniques and details Dictionary driven reuse Provides industry components / Enterprise Data Model Ensures consistency of definition and use Roll your own dictionaries Quick sketch of main aspects of blueprinting approach

5 Exchange Assembly Process Overview
1 Business Modelling Requirements Charter Work Group Project Inception CAM Enabled Dictionary Generation / Selection Model Exchange Blueprints Dictionary 2 Web based Desktop Excel Search tools Import XSD Naming / NDR / spell check Generate Dictionary Import EDM Exchange Content Modelling 3 Expand and Evaluate Results Expand, Review, Refine Completed Exchange Structures NDR Evalu- ation 4 dictionaries Review / Tailor Exchange Structures Each swim lane represents sets of tasks and actions in the process of developing an information exchange. Complete package of artifacts required are generated by CAM tools, also testing and verification reports. This then is ready to publish so that implementers can align their application systems to the specifications and business requirements. In NIEM parlance this is the IEPD – Information Exchange Package Definitions. Notice also the EDM – Enterprise Data Model components can be presented as dictionaries.

6 Leveraging Re-use : Canonical XML Dictionaries
Intelligence Commanders Training Leveraging Re-use : Canonical XML Dictionaries What is a canonical dictionary Styles of dictionary How do I obtain a dictionary? How do I use it with CAM? Foundations of Intelligence 6

7 Canonical XML dictionary
A collection of distinct components that represent discreet business information for an application domain Includes singleton components and combinations of related components together as sub-assemblies Information is represented in a simple neutral conceptual data format that captures the critical concepts about the data e.g. name, description, content type, contextual usage pattern, hierarchy Wikipedia definition:

8 XSD Schema v CAM Dictionary
There are generally two “styles” of XSD schema Distinct information exchange schema structures Collections of schema model components, possibly abstract, and possibly recursive CAM dictionaries built from distinct exchange structures generally mimic those components directly Parent / Child sets are visible in dictionary as ABIE/BBIE pairings “children” column in dictionary contains direct descendents “context” column reflects component relationships CAM dictionaries built from models with abstract and recursive parts may have fragments of components only Assembly of exchange structures using references to piece parts, rather than complete structure assemblies Reuse is then around these extension part collections Context may need to be overridden to meet desired use pattern Examples of two styles of schema – exchange schema: OASIS standard specifications; model schema: NIEM model schema. Notice that dictionary components are to facilitate assembly – so may have duplicates, or merged components sets (e.g. ABIE may appear more than once, or BBIEs only after first ABIE occurrence to use them. This reflects how the dictionary was built – e.g. single step from one CAM template, or multiple merging steps from many CAM templates.

9 Available XML Dictionaries
LEXS 3.1.4 dictionary OASIS EDXL dictionary OASIS EML dictionary NIEM 2.1 dictionaries CBRN dictionary Emergency dictionary Family dictionary Immigration dictionary Infrastructure dictionary Intelligence dictionary Justice dictionary Maritime dictionary Screening dictionary Trade dictionary NIEM core dictionary Immigration blueprint Packaged with CAM editor see dictionary folder of install + spreadsheet + blueprint samples XML XML XML Note: Those marked in bold are model style dictionaries with recursive components.

10 Drag and Drop dictionary into Spreadsheet
Item names Parent item indicator List of Child items Drag and Drop XML dictionary format into Microsoft Excel Child item indicator This shows the components and concepts that underpin the dictionary, viewed as a spreadsheet. This provides a familiar interface for business data analysts to work with. Simply take the XML dictionary file and drag and drop it into Microsoft Excel, click “OK”, and it will open as a workbook. Item Properties Unique ID

11 Creating your own Dictionaries
The CAM toolkit includes dictionary generation tools can harvest components from existing exchange schema will import model components from ERwin modelling tool can ingest and use subset schema or component schema A separate companion Quick Guide describes the dictionary creation processes and tools Look for existing dictionary packs from Sourceforge files location of CAM download

12 Using Dictionaries Determine your business information exchange components at conceptual level Search and locate candidate components from appropriate domain dictionary collections Catalogue the parts to be used Dictionary components can be referenced individually or as collections by an assembly blueprint that puts them all together to create a complete information exchange Components can be selected from multiple dictionaries Note any new extension pieces as needed A control file configures which physical dictionary files to reference and associates one or more particular namespace prefixes with each dictionary The download packs available from Sourceforge contain everything you need to get started; dictionaries, control files, sample blueprints and instructions.

13 Dictionary Control File
Associates physical dictionary files to namespace prefix details This is only required if you are setting up your own new dictionaries from scratch. You can of course review control files to see what dictionaries are referenced. Control files should be manually edited in a XML editor tool to make configuration changes as needed (e.g. arrowed text areas).

14 Introducing Exchange Assembly Blueprints
Intelligence Commanders Training Introducing Exchange Assembly Blueprints What is a blueprint template Example blueprints Blueprint tools overview How do I create a blueprint? How do I use it with CAM? Foundations of Intelligence 14

15 Introducing Blueprints
A blueprint is the outline of your information exchange and the top level sets of components needed Allows rapid iterative exchange structure design Start with a basic idea of what is needed, extend and refine as you clarify groups of components and their relationships Can import components from one or more domain dictionary collections Allows you to focus on the conceptual and hierarchical information model components and their purpose The low level specific information details will be filled in for you by the expander tool from the matching dictionary definitions Review results and add local extensions / exclusions as needed Blueprints themselves also have high re-use value Can be sub-assemblies and patterns not just exchange models

18 How do I create a blueprint?
Use CAM Eclipse visual editor create basic blueprint from scratch or from XML instance Clone and edit an existing blueprint use a XML editor to manipulate raw XML of blueprint (e.g. search and replace namespace details) modify blueprint using CAM Eclipse visual editor Beware of namespaces! You need to pre-declare namespaces in the blueprint – that may appear later in the finished expanded exchange Use CAM Eclipse visual editor root node menu to add namespace definitions Tip: use your XML editor to cut and paste namespaces into raw blueprint XML file directly A blueprint is nothing more than a regular CAM template stripped of everything except the structure section and a top level outline.

19 Blueprint Structure Overview
Short Name for Exchange Root node name and optional namespace XML container elements to facilitate use patterns Dictionary component references A blueprint is nothing more than a regular CAM template stripped of everything except the structure section and a top level outline. Dictionary Type annotation reference (note red paper clip icon) Namespace declarations

20 Adding Components from a Dictionary
Understanding the 4 basic types of component referencing available Direct component (BBIE) Direct collection (ABIE) Indirect type (extension) Indirect sub-component (contextual re-use) Control of the XML structure hierarchy Grouping collections of components Extending an existing component Building new extension from existing components Namespaces – when to use them

21 Example XML Techniques
(Immigration Alien Alert example blueprint) Direct collections referencing (ABIE) Grouping collection of components Direct component referencing (BBIE) Building new component from existing ones Indirect type extension via annotation Type (red paper clip icon denotes annotation) Namespaces – root namespace optional (aaa) Dictionary component namespaces are required

24 Using Your Blueprints What you need - Getting Started
CAM Eclipse visual editor Blueprint template Dictionary or dictionaries of components Dictionary control file Contains linkage of namespace prefix to each dictionary Contains physical filename path of each dictionary Getting Started Install CAM editor tool from Open example blueprint from EDXL folder ~ CAMeditor\eclipse\workspace\CAMEditor\dictionary\blueprints\EDXL Try blueprint expander with control file EDXL-dictionary-control-file.xml

25 Running Blueprint Expander
This example is available in the NIEM dictionaries download pack from Sourceforge Select Dictionary Control File Pick output result filename (default is Determine rule generation selections from dictionary definitions Note: entries are “sticky” so are remembered for next time

28 Hints and Tips Blueprint Remedy Node not expanded, or removed!
Override default dictionary structure context definition using an annotation Type reference to the node instead – see Alien alert example blueprint – aaa:OfficerDetails Added parent and child combination. All children added instead of just one. Expander inserts all children of parent. Either delete unwanted children from expanded result (see next section), or create custom parent node, and pick children components directly – see Alien alert blueprint example. Node not expanded Make sure namespace prefix and spelling exactly matches dictionary and dictionary control file prefixes. Undefined namespace prefix error when opening expanded template in CAM editor Expander added dictionary components from another namespace. Declare that namespace prefix back in blueprint and re-run expander again Expanded result missing all desired sub-components Create your own blueprint extension parent and combine parts to create desired result – see Alien alert example – aaa:FurtherDetails Expanded result has too many sub-components In expanded result mark unneeded parts with “excludeTree” rules, then run File / Export / Compress to strip out; or use extension technique above to pick only few child elements instead of whole parent Some of these techniques are blueprint ones, others involve the expanded result template. Next section covers editing in more details.

46 Running validation rules tests
Built-in CAM validation engine allows testing of XML instances against actual exchange rules (CAMV). Critical to ensure that the exchange validates actual live production example scenarios correctly Allows deployed solution to match exchange schema details Errors can be reviewed interactively in exchange visual interface Post-processing of validation results allows unit regression tests to be created with reporting of errors, warnings and information level notes

47 Run Exchange Template Pick XML test case to validate Run validation

48 Example Exchange Packaging Details
Package Artefact Description CAM Generates Files NDR Evaluation Report Evaluation of exchange template compared to set of Naming and Design Rules (NDR) and interoperability factors / principles Crosswalk XML Itemized list of each dictionary component element and attribute included in the exchange. Exchange Schema Base document schema that defines the full XML structure for the exchange and is generally named after the exchange itself. Extension Schema Specification for extended components—separate local name-spaces of components not contained in dictionary Sample XML Instance Example instance(s) Documentation Master Documentation The Master Document is the main document for which all of the context and details around the exchange are explained. This document includes, the overview, as well as details surrounding the exchange, business drivers and requirements Business rules Business rules in plain or structured English, generated by CAM development tool. Mapping to Dictionary Mapping of domain components, tagged with constraints (i.e., cardinality, etc.) to dictionary components as a spreadsheet. Extended components Components created because they were not in dictionary—may be part of mapping spreadsheet and include structure and definitions of new components.
