Why CMIS?

• Domain Model

• Services, objects, types, properties

• Greatest common denominator

• Transport Protocols

• REST/AtomPub, SOAP Web Services

• No Language API

• ⇒ Apache Chemistry4

Interoperability

• Application / Repository

• Client / Server

• Application ↔ Repository

• e.g. photo management

• Repository ↔ Repository

• e.g. archival, publishing

• Repository federation

• central access to heterogenous systems5

CMIS Benefits

• Customer benefits

• Interoperability between vendors

• Common model

• Desilofication

• Commoditization

• Vendor benefits

• Repository vendors get more apps

• Applications vendors get more repos 6

CMIS Implementations

• Repositories

• Nuxeo, Alfresco, Microsoft, IBM, SAP, eXo, Day, Jahia, KnowledgeTree, ...

• Clients

• Nuxeo, Adobe, IBM, Microsoft, eZ Publish, Plone, Drupal, Joomla, ...

Apache Chemistry

• Incubating project• Started in 2009

• http://incubator.apache.org/chemistry/

• Implement the whole CMIS spec

• Client-side• Java (OpenCMIS)

• Python, PHP, JavaScript

• Server-side• Java (OpenCMIS)

27

Apache Chemistry History

• Original Apache Chemistry project

• Day, Nuxeo in 2009

• OpenCMIS started privately

• Alfresco, Open Text, SAP

• Proposed to Apache in December 2009

• Chemistry and OpenCMIS merge

• 3 days of meetings in April 2010

• OpenCMIS 0.1 released Sept. 201028

OpenCMIS Facts

• 90,000 lines of Java

• OSGi bundles

• 5 JARs needed for a client

• Built with Maven

• Covers all aspects of the spec

• Extensible

• Lots of tests

• Contributors

• Nuxeo, Alfresco, Day, Open Text, SAP...29

Understanding CMIS

30

CMIS Bindings

• AtomPub

• ReST base

• URI templates

• SOAP

• Standardized Web Services

• Browser Bindings (work in progress)

• JSON-based

• ... more are possible 31

CMIS Domain Model

• Objects: Folders, Documents

• Properties

• scalars, lists

• binary content stream

• Types

• inheritance, constraints

• standard properties32

CMIS Services

• CRUD

• Queries

• Versioning

• Renditions

• Change Log

• Repository Info, Types

• (Multi-Filing, ACLs, Relationships, Policies)37

Repository Info

• When connecting, list repositories

• Find out repository capabilities

• Implemented services, tree-based navigation, multi-filing, unfiling, query capabilities, ...

• Get repository-wide information

• Description, vendor, CMIS version, ...

• Root folder ID

• Latest change log token38

Retrieve

• By ID (5ba79978-a87f-4146-9dd4-5197c5ac0962)

• By Path (/default-domain/workspace/main/mydoc)

• By Query on properties / content

• Parent(s) / Children / Tree

• Content Stream

• Allowable Actions

• Renditions39

Query

• Retrieve by properties / content

• SQL-like Language: CMISQL

• Type → Table

• Object → Row

• Property → Column

• Multi-Valued, Fulltext with score, JOIN

• SELECT only

• no UPDATE or DELETE 40

Create, Update, Delete

• Create

• May include a content stream

• Update

• May verify a change token (optimistic locking)

• May change ID (auto-versioning)

• May check in

• Delete

• May delete all versions 41

Versioning

• Version series

• Private working copy

• Check in, Check out

• Get all versions

42

Renditions

• Retrieve only

• Additional content streams

• MIME type, kind, title, size

• Various uses

• thumbnail / icon (current Nuxeo)

• conversions (future)

• PDF, HTML

• Multi-page 43

Relationships

• Source, Target

• Unfiled

• Not versionable

• May use referential integrity

44

Change Log

• List of chronological changes

• Create, update, delete

• ID of object

• (Properties, ACLs)

• Since a given date (change log token)

• May not be available since “forever”

45

Multi-Filing, Unfiling

• Only for documents, not folders

• Zero, one or more parents

• All parents are equivalent

• Different paths

• (If paths are supported)
