Jeremy is a member of the AEC workgroup of the Autodesk Developer Network ADN team, providing developer support, training, conference presentations, and blogging on the Revit API.
He joined Autodesk in 1988 as the technology evangelist responsible for European developer support to lecture, consult, and support AutoCAD application developers in Europe, the U.S., Australia, and Africa. He was a co-founder of ADGE, the AutoCAD Developer Group Europe, and a prolific author on AutoCAD application development. He left Autodesk in 1994 to work as an HVAC application developer, and then rejoined the company in 2005.

About the Presenter
Introduction
§ Determine simplified view of BIM rooms and furniture § Store in cloud database § Display simplified 2D graphics in any browser § Edit furniture position and rotation § Update database and BIM
Room Editor Base Functionality
§ Display sheet, views and floor plan geometry § Revit add-in part implemented
§ Improved 2D graphical editing § Integrated Raphaël.FreeTransform module § Unfortunately it ignores SVG view box transformation
§ Store, edit and update non-graphical property data
Room Editor Update
§ Lazy § ... develop the three great virtues of a programmer: laziness, impatience,
and hubris – Larry Wall § Simple
§ Simplicity is the ultimate sophistication – Leonardo da Vinci § There is no greatness where there is no simplicity – Leo Tolstoy § KISS
§ Perfect § Perfection is achieved, not when there is nothing more to add, but when
there is nothing left to take away – Antoine de Saint-Exupéry
Quotes on Three Fundamental Aspects
§ BIM – Building Information Model § Cloud-based data repository § 2D rendering on mobile device
Data Source, Repository and Consumer Client
§ Graphical room editor on mobile device § Update cloud database § Reflect real-time changes in BIM
Real-time Editing Triggers Database and BIM Update
§ Simple navigation § Home page: list all models, select one § Model selected: list all levels, select one § Level selected: list all rooms, select one § Room selected: display 2D graphical editor,
click and drag furniture § Furniture selected: display and edit properties § Save: update database
§ Note RESTful URLs in the address bar § The database interaction is RESTful as well
Sixty Second First Impression Demo
Free and Simple
§ 100% open source § 200 hours research § < 8 hours to rebuild

§ BIM – Revit § Data repository – NoSQL § Rendering and editing – HTML and SVG
Base Technologies
§ Revit BIM – Revit .NET add-in § NoSQL Database – Apache CouchDB § HTML, SVG – JavaScript, jquery, db, Raphaël
Implementation Environment
§ Same origin policy § Server-side scripting § Two components instead of three
Simpler Still

§ Revit add-in § CouchDB database
The Two and Only Projects
Cloud Database
§ “Not only SQL” § Next generation database paradigm § Address some of the points: non-relational, distributed,
open-source, scalable, huge amounts of data § Frequent other characteristics: schema-free, easy
replication support, simple API, eventually consistent, i.e., BASE, not ACID § http://nosql-database.org, https://en.wikipedia.org/wiki/NoSQL,
http://www.mongodb.com/nosql-explained
NoSQL
§ ACID § Atomicity, Consistency, Isolation and Durability guarantee that database
transactions are processed reliably
§ CAP Theorem § The ACID paradigm cannot simultaneously guarantee consistency,
availability and partition tolerance (distributed system)
§ BASE § Basic Availability, Soft-state, Eventual consistency § Not guaranteed to be in a consistent state at a given moment § Consistency is guaranteed, eventually
http://thebuildingcoder.typepad.com/blog/2014/05/views-displaying-given-element-svg-and-nosql.html#5
ACID versus Base and CAP Theorem
§ Everything is a document § All documents are JSON § Every document has built-in id and revision § The database design is also a document § The design defines views and attachments
CouchDB Database Implementation
§ Relax! § All interactions are REST § Management console is Futon
http://127.0.0.1:5984/_utils/!
§ Access all documents http://127.0.0.1:5984/roomedit/_all_docs!

CouchDB Database Interaction
§ Model – a RVT project file § Level § Room § FamilyInstance represents furniture or equipment § FamilySymbol defines geometry
BIM Model
§ Room has boundary loops and can contain holes § FamilySymbol has a single boundary loop § FamilyInstance has a 2D placement
§ Translation § Rotation
BIM Object Graphics
§ CouchDB ids are Revit unique ids § Family instance → room → level → model § Family instance → symbol
BIM Object Relationships
§ DbObj base class § DbModel § DbLevel § DbRoom § DbFurniture § DbSymbol
NoSQL Database Structure
§ DbFurniture.symbolId → DbSymbol § DbFurniture.roomId → DbRoom § DbRoom.levelId → DbLevel § DbLevel.modelId → DbModel
Database Object Relationships
§ All graphics represented by SVG path element data !<svg width="4cm" height="4cm" viewBox="0 0 400 400"! xmlns="http://www.w3.org/2000/svg" version="1.1">! <rect x="1" y="1" width="398" height="398"! fill="none" stroke="blue" />! <path d="M 100 100 L 300 100 L 200 300 z"! fill="red" stroke="blue" stroke-width="3" />!</svg>!

Revit Add-in Interaction with CouchDB
Conclusion
§ Many! § NoSQL, CouchDB, views, CouchApp and Kanso § JavaScript, SVG, event handling, mobile devices § Mapping to negative Y axis and restore for update § Handle nested database callback functions § Retrieving database changes § Idling versus external event § This is a simple learning sample § Infinite possible real-life applications
Challenges
§ PouchDB – put it in your pocket § Open-source JavaScript database § Inspired by Apache CouchDB § Designed to run in the browser § Work offline as well as online § Store data locally while offline § Synchronize with CouchDB when online § Keep data in sync no matter where
§ http://pouchdb.com
Latest News – On the Road
§ NoSQL is great! § Open source is free and effective § REST and JSON is powerful and simple to work with § Server-side scripting pays off
§ Avoid programming on the mobile device itself § KISS!
