Enterprise�� Application�� #fails





Often CRUD Only• One screen for each record type

• UI maps to table structure• ...or rather, is constrained by the table structure






Relationships to one-degree• “This thing is related to that thing”

• Slow to traverse relationships

• Inhibits discovery by serendipity








So�� what’s�� the�� solution?









Manager/Client:�� “But�� it’s�� new...”

• Only 32% of software projects considered successful

• 44% are considered “challenged”• 24% never get completed

• 50% for project > $1mil

So�� what’s�� the�� solution?













The�� xnlogic�� framework

• RESTful API driven application framework• Declare your model, define your business logic• Framework then produces a domain-specific

JSON and xml api





Advanced�� Features

• Composable models vs Inheritance• Fine-grained security• History Graph for temporal queries• Multi-tenant: • One framework, multiple applications

• Customer segregation





Composable�� Parts

ContactDetails

HasAccounts

HasFriends

HasEmployer

Person

ContactDetails

HasAccounts

Jurisdiction

CorporateDetails

Business

• Composition promotes code reuse (DRY)

• Here, color shows the delta between a Person and a Business model (Hypothetical)

• User permissions are tied to the “Part”

• Parts define properties, relationships, actions and traversals





Simple�� Part�� Definitions

module YourApplication module ContactDetails pacer_vertex

property :address, type: :text property :lat, type: :numeric property :lon, type: :numeric endend

module YourApplication module HasEmployer pacer_vertex

to_one :employer endend





RESTful�� API





Self�� Describing,�� Domain�� Specific�� API

GET /is[ 'contact_details', 'has_accounts', 'has_employer', 'has_friends', 'corporate_details', 'jurisdiction']

GET /model[ 'person', 'business']

PartsThe building blocks of your application

ModelsComposed of Parts





Metadata�� Driven

GET /is/contact_details/metadata{ update_access: true, create_access: true, delete_access: true, parts: [ 'record', 'contact_details' ], descriptive_parts: [ 'contact_details' ], properties: { name: { name: 'name', label: 'Name', type: 'text', unit: null, default: null, validations: { allow_blank: true }, part: 'record', index: true },...

Includes: 1)Current-user’s access rights2)Property definitions3)Relationship definitions4)Validation rules5)Actions/Jobs6)Queries/Traversals





Built-in�� Documentation

GET /is/contact_details/metadata/doc





URLs�� map�� to�� Traversals

GET /model/person/rel/employer[ { meta: { xnid: '/model/business/2028', model_name: 'business', rendered: [ 'record', 'contact_details', ‘has_accounts’, ‘corporate_details’], format: 'partial' }, id: 2028, name: 'Acme Bank', rel: {}, description: 'A very large FI.', created_at: ‘2012-10-02 12:07:31, updated_at: null, address: '88 Fairtrade Blvd., NYC.', lat: '40.755622', lon: '-73.977221', company_url: 'http://www.acme.com', display_name: 'FI - US - ACME' ...},

Returns: 1)All employers of all people
