3. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Goals of Orion •Build developer tooling that works in a browser , •at web scale, •integrating well with existing tools that exist on the web, •based on well ‐ proven web architectures - REST, HTTP, JSON, OAuth, OpenID, and others.

4. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Use Strengths of the Web • zero install on the client • simple connectivity – links • trivial update mechanism • powerful rendering engine • look and feel easy to adapt • large, activecommunity • innovation by everyone • no central “IDE” • artifacts all over the web • highly distributed content • refresh the page • scalable computing power

5. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Why work on this now? •There are other online IDEs already, extremely high rate of innovation in online tools for web development •We need to start now, learn, fail, try again, in order to become a player in this space •We (IBM) would like to see a community to form around this forms at Eclipse, and are contributing a seed

6. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. A Glance at Web Architectures - REST • An important concept in RESTis the existence of resources (sources of specific information),each ofwhich is referenced with a global identifier (e.g., a URI in HTTP). In order to manipulate these resources, componentsofthe network (user agentsand origin servers) communicate via a standardized interface (e.g., HTTP) and exchange representationsofthese resources (the actual documentsconveying the information).

8. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. A Glance at Web Architectures •HTTP - a networking protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the WWW •Ajax - a group of interrelated web developmentt methods used on the client-side to create interactive web applications. With Ajax, web applications can retrieve data from the server asynchronously in the background

9. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. A Glance at Web Architectures •JSON - a lightweight text-based open standard designed for human-readable data interchange • JSON vs XML picture

11. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. •OAuth – an open standard for authorization, which allows users to share their private resources stored on one site with another site without having to hand out their credentials

12. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Orion Assumptions •Software development in a browser  editing  navigating folders  searching  working with SCM •Set of linked web pages, NOT an IDE running in a browser  easy to integrate other functionality even if hosted on different servers

17. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Context: Already in a Browser •Bug tracking (Bugzilla, JIRA, Trac, Lighthouse, Rational RTC) •Builds (Hudson/Jenkins) •Code review (Bugzilla, Gerrit, GitHub) •Documentation, code snippets (pastebin, Gist) •Browsing code repositories (GitHub, ViewCVS, Rational RTC) •Debugger (Firebug, WebKit Inspector, Developer Tools)

18. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. What’s Missing? Not Much •Code editor •Navigator •Work with SCM(commit, compare, merge, etc) •Indexing - full text search •Unit tests •Initial focus on web developers working on client-side JavaScript, HTML,CSS

19. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Orion Design Principles •Regular hyperlinks, back button, bookmarking,link sharing •Functionality on separate pages. Page = Task + Resource •Performant and Lightweight. Speed trumps power. •Components should have value on their own. •Low barrier of entry for adopters. Don’t require technology buy‐in.

21. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Integration Possibilities •Client-side “plug-ins” : adding commands to existing UI  Integrate withSCMs:  Git is used to speed up self-hosting  There is ongoing effort on enabling RTCin Orion  W3C validator, JSLint, ... •Hyperlink integration  Bugzilla, Gerrit, SCM stats •Integrate with browser debuggers:  Firebug, WebKit Inspector •Host additional UI components, e.g. OpenSocial Gadgets •Server-side  OSLC: Consume and produce server APIs

22. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Integration Possibilities (cntd.) •Web-Based integration  initializr.com - equivalent of “New Project” wizard  smush.it - lossless “compression” of images  CSS Sprite Generator  jsbeautifier.org - JavaScript code formatter

23. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved. Integration Possibilities (Demo) • Create project initializr.com • Import zip • Disable jslint • Go to page (comment in log)
