State of the CMIS TC"•  CMIS 1.0 errata – Any day now?"•  CMIS Technical Committee working on CMIS 1.1"•  Already talking about issues and ideas for CMIS 2.0"

CMIS Refresher"

Domain Model •  Data Model"•  Services"

Protocol Bindings •  RESTful AtomPub"•  Web Services"

CMIS Refresher"

Repository •  Contains folders, documents and other objects"•  Must provide all basic services in the CMIS specification"•  Must provide REST and SOAP bindings"•  Advertises capabilities through a service"

CMIS Refresher"

Object Types •  Stricly-typed data model"•  Each object has an object type"•  Four base object types:"

•  Document, Folder, Relationship & Policy"•  Base types may have sub-types"

CMIS Refresher"

Properties •  All objects have properties"•  A property holds zero to many typed values"•  Property definitions have attributes"

•  Common attributes e.g. ID, PropertyType, Cardinality"

•  Property type specific attributes e.g. precision for decimals"•  Property data types"

•  String, Boolean, Decimal, Integer, Datetime, Id, Uri and Html"

CMIS Refresher"

Documents •  Instance of the document base type or sub-type"•  Documents have properties and optionally a content stream and

renditions"•  Content streams are normally set and retrieved in separate operations"

•  Documents may be versionable"

CMIS Refresher"

Folders •  Folders can contain folders and documents"

•  Any other kind of object that is declared to be fileable"•  Folders cannot have more than one parent folder"•  Folders can decide what types they contain"

•  A folder can specify it may only contain document of a given content type"•  Documents may optionally be unfiled"•  Documents may optionally belong to multiple folders"

CMIS Refresher"

Relationships •  A directional relationship between any two objects"•  An object can have any number of relationships including with

itself"•  A relationship has a source and target but this ʻdirectionʼ has no

CMIS-defined semantics"•  Referential integrity is not enforced"

•  When the relationship is created, both end-points must exist"•  Repository support for relationships is optional"

CMIS Refresher"

Policies •  An administrative policy that can be enforced by a repository"•  Used to manage objects in ways that are, by themselves, outside

the scope of CMIS"•  Such as records retention"

•  policyText property contains the details of the policy"•  Policy text is opaque to the CMIS repository"•  Repository support for policies is optional"

CMIS Refresher"

Access Control •  Permission"

•  An allowed action (read, write, all)"

•  Mapping to allowed actions is repository specific and discoverable"•  Principal – a user or a group"•  Access Control Entry (ACE)"

•  One or more permissions granted to a Principal"•  Access Control List (ACL)"

•  A collection of ACEʼs"

•  Can be assigned to an object and can be propagated"•  Repository support for Access Control is optional"

CMIS Refresher"

Versioning •  A document may be versioned as indicated by the type definition"•  Versions represent the properties and content of a document at a

given point in time"•  All versions of a document collectively define its Version Series"•  CheckOut creates a Private Working Copy which can be edited

and checked in"

CMIS Refresher"

Query •  Based on well known standard – SQL-92"

•  With ECM extensions added"•  Each type is treated as a logical relational table"•  Joins may be supported"

•  Either inner, or both inner and outer joins"

•  Repository specific behavior"•  Query supports metadata and/or full-text"

•  Repository support for full-text search is optional"

CMIS Refresher"

Services •  Eight sets of services:"

•  Repository, Object, Discovery, Navigation, Versioning, Relationship, Policy and ACL"

•  Support for create, read, update and delete operations for various types"

•  Some examples:"•  Repository Services: getRepositories, getRepository, getTypeDefinition"

•  Navigation Services: getChildren, getFolderParent, getObjectParents"

•  Object Services: createDocument, createFolder, getObject, getObjectByPath, getContentStream, deleteObject"

•  Versioning Servcies: checkOut, cancelCheckOut, checkIn, getAllVersions"

CMIS Refresher"

Protocol Bindings •  Providers must implement RESTful AtomPub and SOAP"

RESTful AtomPub •  Feeds, entries & links"•  GET, POST, PUT, DELETE"•  Example: createDocument by POST to parent folderʼs collection"•  Recommend HTTP Basic Authentication"

Web Services •  SOAP"•  WSDL and XSD are defined in the specification"•  Recommend Basic Authentication and WS Security

UsernameToken"

Coming Soon – CMIS 1.1"

Browser Binding – CMIS-719 •  Designed to allow developers to build browser based applications"•  Use already understood technologies including"

•  HTML, HTML Forms, JavaScript and JSON"

•  Does not require a JavaScript library"•  Optimized for use in a browser, also useful for HTTP based

bindings for other application types"

Browser Binding – CMIS-719 •  HTTP Protocol"•  Predictable URLʼs"•  JSON Data Representation"

•  Described by orderly: http://orderly-json.org"CMIS JSON

String string

Boolean boolean

Decimal number

Integer number

DateDme number (milliseconds since 1970/01/01, UTC)

Uri string

Id string

Html string

Browser Binding – CMIS-719 •  Uses HTTP GET and POST exclusively"

•  HTML forms used to POST content must include “cmisaction” to describe the action to perform e.g. createDocument, createFolder, etc."

•  Various controls specified per operation"•  Demo in a few minutes"•  Details here:"

•  http://bit.ly/tlACld"

Type Mutability – CMIS-669 Use Cases

•  CMIS Application needs to install its own metadata and uninstall if removed"

•  CMIS Repository migration application would not only migrate documents from one repository to another; but would be able to migrate and preserve the metadata as well"

•  General purpose Administration applications that allow administrators to edit metadata for new systems"

Type Mutability – CMIS-669 Requirements

•  Must be optional and backward compatible with 1.0"•  Must be implemented in a way such that is it obvious to someone

familiar with CMIS 1.0 how these operations would be implemented"

•  POST to the ʻTypes Childrenʼ collection creates a new type, etc."•  Must allow an application to setup new types with associated new

properties"•  Optionally allows an application to delete types it has created"•  Exposed schema changes will be confined to a small footprint"•  A Type Mutability aware CMIS 1.1 client MUST work fine with a

CMIS 1.0 (non Type Mutability) aware server"

Type Mutability – CMIS-669 •  Discoverable Optional Capability exposed on a type"

•  cmisTypeMutabilityCapabilitiesType enum"

•  create (new child types), update, delete"•  New services: createType, updateType and deleteType"•  Details here:"

•  http://bit.ly/v9zeYg"

Secondary Object Types – CMIS-713 •  Aspects!"

Use Cases •  Additional metadata has to be attached after the document has

been created"•  Adding a new set of properties is necessary for some business

cases"•  Some technical metadata derived from the content can only be

added after the repository has analyzed the content"•  Some common and crosscutting concepts such as tags, comments

and ratings can be implemented with secondary types."•  Secondary types and their properties can reveal and control the

status of an object. Examples are legal holds, workflows, storage/archiving information, publishing information, etc."

Secondary Object Types – CMIS-713 •  New base type: cmis:secondary "•  Other base types have new attribute:

cmis:secondaryObjectTypeIds "•  Added to updateProperties and checkIn services"•  Properties are returned via query operations"

•  Can be filtered using property filter syntax"•  Details here:"

•  http://bit.ly/syhlzW"

Approved •  CMIS Repository Extensions (CMIS-693)"•  Allow Creation of Unfiled Documents with AtomPub (CMIS-711)"•  Description Property for all Base Types (CMIS-712)"•  Retention & Hold (CMIS-714)"

•  Currently proposed to split these into separate proposals"

Under Consideration •  External Content Reference (CMIS-705)"•  Batch Operations (CMIS-727)"•  Is PWC the latest version? (CMIS-728)"•  Query Wildcard Clarification (CMIS-729)"

Demo!"

Browser Binding in Alfresco •  More efficient than Web Services and the AtomPub binding"•  Florianʼs CMIS Webinar: http://bit.ly/tTW9ZX"•  Florianʼs Slides: http://slidesha.re/uL8IKI"•  Try it! http://cmis.alfresco.com/"

Whatʼs in the Future? – CMIS 2.0"

•  Pessimistic Locking (CMIS-196) •  Multiple Content Streams on Documents (CMIS-432) •  Remove base64 content stream encoding (CMIS-466) •  Reconsider Renditions Implementation (CMIS-645) •  Annotations (CMIS-722) •  Tagging (CMIS-726)
