CMIS in the “real world”

Or “Why bother writing custom APIs when you have standard ones”?

Agenda

How did we get here? •  From Babel to Esperanto •  CMIS quick reference card

How & What can I build? •  Apache Chemistry state of the nation •  What can I do with CMIS? •  Application to Repository (a2r) •  Repository to Repository (r2r)

How people use CMIS? •  CMIS & Alfresco •  a2r CMIS product integrations •  CMIS performances

We have a dream!

CMIS Domain Model

Apache Chemistry

CMIS Bindings

Nice theory but … Tools anyone?

Open Source implementations of

•  Apache Chemistry (http://chemistry.apache.org) is the umbrella project for all CMIS related projects within the Apache Software Foundation.

•  Apache Chemistry provides libraries and frameworks for •  Java (Client and Server) •  Python (Client) •  PHP (Client) •  .NET (Client)

Java OpenCMIS (current version: 0.5.0) •  Mature •  High spec coverage and major testing •  Client API / Server SPI

•  Goodies •  In memory & fileshare test servers •  Swing Workbench •  OSGi bundles

•  OpenCMIS is available •  as source code:

https://svn.apache.org/repos/asf/chemistry/opencmis/trunk/

•  as release package with all dependencies: http://chemistry.apache.org/java/download.html

•  via Maven: http://chemistry.apache.org/java/developing/dev-use-with-maven.html

State of the Nation

OpenCMIS details

What does OpenCMIS give me? •  Object oriented Client API •  Ease of use and focus on domain model •  Concept of session (CMIS is stateless)

•  Performance focus •  Caching •  Repository infos •  Type definitions •  AtomPub links •  CMIS objects

•  Compression •  CMIS XML compresses very well

•  Docs & Samples •  http://chemistry.apache.org/java/developing/index.html •  http://svn.apache.org/repos/asf/chemistry/opencmis/trunk/

chemistry-opencmis-samples/

OpenCMIS details

Python cmislib (current version: 0.4.1) •  Mature, tested against major servers •  Available as egg, zip, tar.gz

PHP lib(current version: unreleased) •  Basic coverage of the spec •  Used in a few productions site & for the Drupal integration

DotCMIS (current version: 0.3) •  Quite mature, good coverage of the spec •  Single DLL •  Requires more testing

Browser binding (experimental on CMIS 1.1 branch)

Other clients

All nice, but what can I build with CMIS?

CMIS use cases

Application to repository (A2R) •  ”App uses a content repository to handle content services” •  Neat separation of frontend and content tiers •  Examples: •  Portal (e.g.Liferay) or Intranet (e.g. Drupal, Sharepoint) •  Custom webapp or desktop application (e.g Office apps)

Repository to repository (R2R) •  “This is where content repositories talk directly to each other” •  CMIS is flourishing, easy inter vendor communication •  Examples: •  Legacy Content Migration •  Content Publishing or Archival

Federated repositories •  Mix of the 2 above: application talks to multi repositories

CMIS & Alfresco

(Open)CMIS is key to Alfresco strategy •  CMIS client/server enhancements •  Alfresco OpenCMIS Extension •  OpenCMIS Server as of Alfresco 4.0 •  Spring Surf OpenCMIS Client integration

•  Products •  Web Quick Start •  Alfresco iPhone / iPad Mobile App

•  Internal processes •  Team (http://team.alfresco.com) & soon Partner

(http://partners.alfresco.com) based on Drupal Alfresco CMIS integration

CMIS allows seamless integrations with Alfresco •  Social integration (Jive, Liferay, Drupal) •  OpenCMIS clients / product integration (OpenWorkdesk)

Alfesco OpenCMIS Extension

CMIS Extension for discovering / managing aspects

•  Aspects are an essential tool to model metadata in Alfresco. The CMIS specification does not define aspects or something similar, but it defines several extension points.

•  CMIS extensions are XML fragments placed in different parts of a CMIS object. (CMIS/Atom extensions are not fun to work directly with…)

•  “Alfresco OpenCMIS Extension” seamlessly merges aspect properties with object properties and provides interfaces to get, add and remove aspects.

•  It does that by replacing OpenCMIS' internal object factory with an object factory that is aspect aware.

Alfesco OpenCMIS Server

Starting from Alfresco 4.0: •  Alfresco CMIS based on the OpenCMIS server framework •  Why has it been re-implemented? •  OpenCMIS is used by several CMIS repositories. •  One code base for the AtomPub and the Web Services binding

(and the Browser Binding). •  Better CMIS specification compliance. •  Better performance, less memory consumption,

handling of big documents.

What changes? •  Old URLs still valid but deprecated •  Generic clients should not notice differences •  Alfresco Extension keeps on working! •  JSON Browser binding prototype (disabled by default)

Alfesco iOS Mobile App

iPhone / iPad app for Alfresco 3.4 + (or Team)

•  Heavily CMIS based (+ some custom Webscripts)

•  Initial Implementation of an Objective-C CMIS client

•  Code will be open sourced during DevCon

Features •  Read, open & save documents •  Search documents •  Upload and tag photos / video •  Look for Marc

Spring Surf (Webscripts) and OpenCMIS

Starting from Alfresco 4.0: •  OpenCMIS client libs available in webscripts •  Use cases •  Repository •  Light Migrations / Synchronization •  Publishing

•  Web Tier •  CMIS Enabled Frontend •  Federated application frontend

How to use it? •  New JavaScript top level object: cmis •  Three connection types: •  Current Alfresco server (uses OpenCMIS local binding if possible) •  Preconfigured connection •  Web script configured connection

Will be available with Jive 5.0. Ask Peter Monks

Coupled

•  Thousands of modules •  Easy to theme •  Fast, efficient development

model

•  Multiple ways to update content •  Robust business process engine •  Extensible content model

Best of both worlds

Mature integration •  Based on the Chemistry PHP CMIS module •  GA in the Drupal community (http://drupal.org/project/cmis) •  AppNovations Canopy: commercial solution at

And Liferay?

Many levels of integration •  UI Integration DocLib portlet

•  DocLib Content only CmisHook in LR 6.0 http://www.liferay.com/web/jonas.yuan/blog/-/blogs/integrating-alfresco-through-cmis-in-liferay

•  DocLib Content + Metadata Multiple CMIS repos in LR 6.1 http://www.liferay.com/web/alexander.chow/blog/-/blogs/7670631

Common integration pattern for Alfresco customers •  Typical Frontend intranet / extranet solution •  Common pitfalls •  No CMIS, totally custom Webscript interface (so 90’s) •  Lack of tuning performance •  No inter tier caching

Why not CMIS?

Liferay + Alfresco DM (contents) . 6 millions pages view / year. 80.000 bookings per year. 6th biggest turistism portal in the world.

CMIS usage sheet - Recap

CMIS does •  Offer MCD for ECM •  Aspects targeted for 1.1

•  Provide mature tooling •  Enable separation of

content and web tier •  Simplify multi vendor /

technology integration •  Remove the burden of

custom API maintenance

CMIS does not •  Cover all ECM aspects •  E.g. users or workflow

•  Compare performances of in process integrations

•  Suit for •  Large migrations •  Ultra high performant and

concurrent scenarios •  Work “one size fits all” •  Requires developer

knowledge of the APIs •  Requires performance

tuning

OpenCMIS design & performance tips

Get only what you need… •  Only ask for the properties

you need! •  Never do perform

“SELECT * FROM …” queries •  Select sensible page sizes

and depths •  Operation Context

…when you need it! •  Tune Sensible caching •  OpenCMIS and DotCMIS

have first-level caching build in. Use it & add your application caching

Tune client… •  Enable HTTP Keep Alive •  Speed up burst of requests

•  Read content streams •  And close them!

•  Use compression for high latency / low bandwidth •  Enable in Session Parameters

…and server! •  Alfresco 4.x OpenCMIS

server faster than 3.4 •  repository-bm module

allow benchmark of •  CMIS Sequential •  CMIS mixed

Thanks!
