The Social Web

The Social Web
People and Connections
Activity Streams / News Feeds
Messaging / Notiﬁcations

APIs?


The Solution
Gadgets from iGoogle

Add People, Activities, and Viral
Javascript APIs

Open to all

Iterate..


And Then...
OpenSocial Foundation
Hackathons
Atom/XML/Json REST APIs
OpenSocial Templates
Data Pipelining
Portable Contacts
OAuth
Activity Streams?


End Result

Shindig

Shindig Architecture

• Gadget Server/Renderer

• OpenSocial data server
(REST, Atom, JSON-
RPC)

• People/Activities/
Messages/Persistence
Interfaces.


Extra Features
• Proxy Server

Java Implementation
• Uses Composition and Dependency
Injection via Guice.
• People/Activities/AppData/Messaging
Services.
• Authentication and Security
• Hooks for just about everything else.


Integration Basics
• Implement Interfaces - People, Activities,
Data, Messaging
• Review shindig.properties, container.js
• Write Guice Module
• Add to web.xml
• Add more - HttpFetcher, HttpCache,
SecurityTokenDecoder, etc.


PeopleService
public Future<RestfulCollection<Person>>
getPeople(Set<UserId> userIds,
GroupId groupId,
CollectionOptions options,
Set<String> fields,
SecurityToken token) throws ProtocolException {
...
}

public Future<Person>
getPerson(UserId id,
Set<String> fields,
SecurityToken token) throws ProtocolException {
...
}


ActivityService
public Future<RestfulCollection<Activity>>
getActivities(Set<UserId> userIds,
GroupId groupId,
String appId,
Set<String> fields,
SecurityToken token);

public Future<Void>
createActivity(UserId userId,
GroupId groupId,
String appId,
Set<String> fields,
Activity activity,
(and more....)


AppDataService
Future<DataCollection>
getPersonData(Set<UserId> userIds, GroupId groupId,
String appId, Set<String> fields,

Future<Void>
deletePersonData(UserId userId, GroupId groupId,

Future<Void>
updatePersonData(UserId userId, GroupId groupId,
Map<String, String> values,


MessageService
Future<RestfulCollection<MessageCollection>>
getMessageCollections(UserId userId,
Set<String> fields,

* also create/modify/delete

Future<RestfulCollection<Message>>
getMessages(UserId userId, String msgCollId,
Set<String> fields, List<String> msgIds,
CollectionOptions options, SecurityToken token);

* also create/modify/delete


Guice Module
package com.example.MyGuiceModule;

public class MyGuiceModule extends AbstractBaseModule {
protected void configure() {
bind(PeopleService.class).to(MyPeopleService.class);
bind(ActivityService.class).to(MyActivityService.class);
bind(AppDataService.class).to(MyAppDataService.class);
bind(MessageService.class).to(MyMessageService.class);
}
}


shindig.properties
• 42 Parameters at last count
• Global Cache Params
• Global RSA key for OAuth signed
requests
• Bound via Guice in the code
• @Named(“shindig.param”) String param

container.js

• Support for multiple containers
• Defines supported fields, url paths
• Should match web.xml config


web.xml
• Copy web.xml

• java/server/src/main/webapp/WEB-INF/web.xml

• Add Guice Module

<content-param>
<param-name>guice-modules</param-name>
<param-value>com.example.MyGuiceModule</param-value>
</context-param>


More!
• Customize HttpFetcher • GadgetSpecFactory for
for security localized control of
GadgetSpecs
• OAuthDataStore OAuth
API Access. • OAuthStore for
proxying OAuth
• SecurityTokenDecoder requests
to link with your existing
security infrastructure.

• ExecutionListener for
logging and analytics


Container to Platform
• Add Schemas for Data

• Apps, Developers,
Permissions,
Notiﬁcations, App
Invites

• Add UI Elements
