![Page 3: Alfresco CMIS Webinar Final](https://reader033.fdocuments.us/reader033/viewer/2022061119/546b9318b4af9f80038b4769/html5/thumbnails/3.jpg)
Background / History
● Founding members● IBM, Microsoft, EMC
● Timeline● Spec as been in development for
approx 2 years
● Contributing Members invited Aug 07
● Draft Spec Submitted to OASIS 10th Sept 2008
● Contributing members● Alfresco, Open Text, SAP, Oracle
(BEA)
● Approach● Standardizing existing ECM
implementations
● Minimizing initial scope
● For broad acceptance

What is CMIS?
● “The objective of the CMIS standard is to define a common content management web services interface that can be implemented by content repositories and enable interoperability across repositories.”
● A (draft) standard defining APIs to support interoperability with ECM systems
● CMIS defines:● Model e.g. Types, Relationships● Standardised Query Language● Protocol Bindings e.g. REST, Web Services● Services e.g. Check out/in, versioning
![Page 5: Alfresco CMIS Webinar Final](https://reader033.fdocuments.us/reader033/viewer/2022061119/546b9318b4af9f80038b4769/html5/thumbnails/5.jpg)
Why CMIS?
● Most large organisations have multiple ECM solutions
● No standard across ECM systems● Proprietary specific APIs● Proprietary Query interfaces● Language dependent Java vs .Net …
● One-off integrations● No reuse● Expensive to implement, maintain

Target Use Cases
● Collaborative Content Creation● Authentication, Checkin/out, Version
Control
● Portals● Browsing, properties, indexing, search
● Mashups● URL addressability, properties
● Archival Applications● Properties, indexing and search
● Compound Documents● Relationships
● Electronic Legal Discovery● Versioning, properties, indexing,
search

Non-Target Use Cases
● Maybe addressed in future CMIS versions
● Records Management & Compliance● Retention schedules, classification, legal holds
● Digital Asset Management● Renditions, streaming
● Web Content Management● Templates, staging, preview, deployment . . .
● Subscription/Notification Services● Event triggers

CMIS and Other Standards
● Why not using an existing standard?
● WebDAV● No types and properties
● No Query
● No relationships
● Tied to HTTP
● Atom Publishing Protocol (APP)● HTTP and resource specific
● Note: CMIS builds on APP conventions
● JCR-170/283● Java Only
● Too prescriptive
• Requires changes to core ECM capabilities to support specific features and models
● Not service oriented
• Requires persistent connections
• Unsuited to Mashups

CMIS Specification Status & Next Steps
● Successful Vendor Interoperability Workshop● All 7 vendors● CMIS Providers and Clients Tested
• REST and Web Services Protocol Bindings
● Draft submitted to OASIS 10th Sept 08
● Technical Committee Formed
● First Meeting 25th Sept 08
● Official Ratification TBD

Specification Overview
● Part I - Encapsulates ECM experience● Defines Domain Model● Defines Services i.e. interaction with Model● Common to ECM repositories
● Part II – Map Part I to Protocol Bindings● SOAP / WSDL
• Leverage years of investment in infrastructure/tools• Service-oriented• Content Repository orchestration
● REST• “Web 2.0” stack• Resource-oriented• Content syndication / publishing

CMIS SOAP Binding
● WSDL definition…● XML schema for CMIS Domain Model● XML schema for Service messages● Direct exposure of CMIS (Part I) Services● Generate client API for almost all languages
● WS-Security & Username Token Profile (MUST)
● WS-I Basic Profile & Basic Security Profile
● MTOM content transfers

CMIS REST Binding
● ATOM Publishing Protocol● ATOM syndication format for web feeds (GET)
● Create & update web resources (POST, PUT, DELETE)
● Extension mechanism supported
● CMIS extension● XML Schema for CMIS Domain Model
• As used in SOAP Binding
● New Web Resources / Method mappings
● Use any existing HTTP or ATOM client API
