    • Tech Talk Live: Alfresco Public APIUpdateApril 3, 2013Peter Monks, pmonks@alfresco.comGreg Melahn, greg.melahn@alfresco.com
    • Agenda•  Overview•  What’s New•  Demo of the API in Action•  Roadmap•  Questions and Answers
    • OverviewFolder, file, content Networks, sites,and metadata people, comments,manipulation and tags, activities, …search
    • Overview
    • Overview •  API URLs are structured: –  Tenant –  API scope –  API name –  API version –  Entity type*https://api.alfresco.com/acme.com/public/alfresco/ versions/1/sites * The notion of entity types doesn’t apply to CMIS.
    • Overview•  The entity type URL represents a collection of all instances of that entity –  The collection may or may not be retrievable via a GET•  Each instance of an entity can be accessed via the collection URL with an Id appended .../acme.com/public/alfresco/versions/1/sites/mullet-gallery
    • Overview •  Entity types may also be nested.../acme.com/public/alfresco/versions/1/sites/mullet-gallery/members •  The same rule about retrieving instances by Id applies .../acme.com/public/alfresco/versions/1/sites/mullet-gallery/ members/pmonks@alfresco.com
    • Overview•  Creating a new entity instance: –  POST to the collection URL•  Updating an entity instance: –  PUT to the instance URL•  Deleting an entity instance: –  DELETE against the instance URL•  These rules apply regardless of whether it’s a top-level or nested collection
    • OverviewAs of today:•  Only the “public” API scope is exposed•  API names are: –  alfresco –  CMIS•  Alfresco top-level entity types are: –  sites –  people –  tags –  nodes
    • Overview•  Over time the API will grow simply by adding new entity types•  All new entity types will follow the same rules•  The APIs (tenants, API scopes, API names, API versions, entity types, etc.) are fully discoverable –  No more relying on Alfresco version numbers!
    • What’s New•  oAuth Key Improvements•  Favorites API•  Site Membership Request API
    • oAuth Key Improvements•  Refresh keys last longer – now 28 Days•  Still secure, but more convenient!•  Users returning from leave won’t need to re-authenticate{ "access_token":"ad299019-c308-4588-84e6-fc76ee73fb35", "token_type":"Bearer", "expires_in":3600, "refresh_token":" ", "scope":"public_api"}
    • Favorites API•  Favorites ( ) or Favourites ( )?•  A new Entity Type•  A new Collection under Person –  people/<personId>/favorites!•  Sites, Folders and Files can be made Favorites•  Introduction of the WHERE parameter for filtering of the favorites result set
    • Entity TypeProperty Type JSON Type DescriptiontargetGuid id string The guid of the entity that is a favoritecreatedAt date time string The date and time the object was made a favoritetarget object object The object that is a favorite. This can be site, a folder or a file
    • API Patterns•  Getting favorites –  HTTP GET people/<personId>/favorites!•  Getting a favorite –  HTTP GET people/<personId>/favorites/ <targetGuid>!•  Adding a favorite –  HTTP POST people/<personId>/favorites!•  Removing a favorite •  HTTP DELETE people/<personId>/favorites/ <targetGuid>! No PUT needed because the Favorite entity has no properties that can be modified by the client.
    • Example – Getting FavoritesRequest HTTP GET people/fred.bloggs@example.com/favoritesPaging parameters (skipCount and maxItems) can be used to control response size.
    • Example – Getting Favorites Response HTTP 200 OK ! {  
  ! ! !"list" : {!    ! ! !  "pagination" : {!       ! ! ! !"count" : 3,!       ! ! ! !"hasMoreItems" : false,!     ! ! ! !"skipCount" : 0,!       ! ! ! !"maxItems" : 100! },! ! ! ! "entries" : [! ! ! ! {! "entry" : {
     "targetGuid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",
     "createdAt" : "2012-07-20T21:46:09.659+0000",
      "target": {
    "site" : {!     "id" : "foo",! "guid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",! ! ! ! ! "title" : "The Foo Site",! "visibility" : "PRIVATE",! ! ! ! ! "description" : "The Foo Site",! ! ! ! ! ! "role" : "SiteManager”! ! ! ! }! ! ! ! }! ! ! ! }
 ! ! }, … more entries (one per favorite)
    • Example – Getting a FavoriteRequest HTTP GET people/fred.bloggs@example.com/favorites/8ac18731-601b-4bb4-be1a-cd5d252cce3f!! ! !
    • Example – Getting a Favorite Response HTTP 200 OK! ! ! !{! "entry" : {
    "targetGuid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",
     "createdAt" : "2012-07-20T21:46:09.659+0000",
    "target": {
   "site" : {!     "id" : "foo",! "guid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",! ! ! ! "title" : "The Foo Site",! "visibility" : "PRIVATE",! ! ! ! ! "description" : "The Foo Site",! ! ! ! ! !"role" : "SiteManager”! ! ! ! ! }! ! ! ! }! ! ! ! }
 ! ! } Notice we return the role as a convenience to reduce the need for more requests later
    • Example – Adding a FavoriteRequest HTTP POST people/fred.bloggs@example.com/favorites! {! "target": {
 "site" : { ! "guid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f"! } !  }
 }
    • Example – Adding a Favorite Response HTTP 201 Created ! ! ! !{! "entry" : {
    "targetGuid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",
     "createdAt" : "2012-07-20T21:46:09.659+0000",
    "target": {
   "site" : {!     "id" : "foo",! "guid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",! ! ! ! "title" : "The Foo Site",! "visibility" : "PRIVATE",! ! ! ! ! "description" : "The Foo Site",! ! ! ! ! "role" : "SiteManager”! ! ! ! ! }! ! ! }! ! ! }
 ! ! }
    • Example – Removing a FavoriteRequest HTTP DELETE people/fred.bloggs@example.com/favorites/8ac18731-601b-4bb4-be1a-cd5d252cce3f!!Response HTTP 204 No Content! !
    • Introducing the where parameter •  Used to limit the response to only those favorites meeting certain criteria •  Uses an SQL like predicate, EXISTS •  JSON pointer syntax used as values –  target/file –  target/folder –  target/site •  e.g. where=(EXISTS(target/file) OR EXISTS(target/folder))
 !
    • Site Membership Request API•  A new Entity Type•  A new Collection under Person –  people/<personId>/site-membership- requests!•  Requests to join moderated sites go into the approval workflow just as in the Share app•  Requests to join public sites are implicitly granted•  Requests to join private sites are just ignored –  and a 404 hides the existence of the private site•  You can only request to join a site in your own network
    • Entity TypeProperty Type JSON Description Typeid id string The id of the sitesite object object The site for which this is a requestmessage string string A message from the requester explaining why membership in the site is being requested (optional)createdAt date time string The date and time the site membership request was mademodifiedAt date time string The date and time the site membership request was changed
    • API Patterns•  Getting a list of site membership requests –  HTTP GET people/<personId>/site-membership- requests!•  Requesting to join a site –  HTTP POST people/<personId>/site-membership- requests!•  Changing a request –  HTTP PUT people/<personId>/site-membership- requests/<siteId>!•  Withdrawing a request •  HTTP DELETE people/<personId>/site-membership- requests/<siteId>
    • Example – Getting a List of SiteMembership Requests Request HTTP GET people/fred.bloggs@example.com/ site-membership-requests!
    • Example – Getting a List of SiteMembership Requests Response HTTP 200 OK ! {  
  ! ! !"list" : {!    ! ! !  "pagination" : {!       ! ! ! !"count" : 3,!       ! ! ! !"hasMoreItems" : false,!     ! ! ! !"skipCount" : 0,!       ! ! ! !"maxItems" : 100! ! ! },! "entries" : [!   {                                            
      ! ! !    "entry": {                                 
           "id" : "the-secret-site",
           "createdAt" : "2012-07-20T21:46:09.659+0000",
           "modifiedAt" : "2012-07-20T21:46:09.659+0000",
           "message" : "I am working on the secret project too!", ! "site" : {! "id" : "the-secret-site",! "guid" : "8ac18731-601b-4bb4-be1a-cd5d252cce3f",! "title" : "The Company’s Secret Site",! "visibility" : "MODERATED",! "description" : "The Company’s Secret Site"               ! }! }!           }, … more entries (one per request)
    • Example – Requesting to Join aSite Request HTTP POST people/fred.bloggs@example.com/ site-membership-requests! ! {                                 
    "id" : "the-secret-site",
    "message" : "I am working on the secret project too!"
 }

    • Example – Requesting to Join aSite Response HTTP 201 Created ! {                                            
      ! ! !   "entry": {
