What’s this Flower ?

Services Tutorial

It’s Alfresco !

An Open Source ECM Solution

Where is the Problem ?

Curious people who want to understand Alfresco…

With lots of questions…(To express…)

A possible solution…

Simply a presenter with presentations about Alfresco

with a few answers… (To verify)

Let’s do it !

But before, don’t forget…

…THE principle…Everything is NODE

What a beautifulNode!!!

Now, let’s go!

OK, nodes are really cool… But what if I want to manage them ?

Let's explore the notion of service…

A Service ?

• Activity, carried out by someone or something, that serve a cause or help a person.

What kind of services does Alfresco offer ?

Services for managingNODES

Who are you to manage me ?

How to access

services?

With the Service Registry !

Service Registry ?

Yes ! THE service registry ! Introduction…

Alfreso Service Registry

…

OK…Explanation…

a registry ?• Official service or

place where you can find and call/use the services

• NB : an equivalent would be your phone book or directory!

Hello, I’m Alfresco Service Registry

I know and I have all Alfresco services !

I’m NodeService !

Me, My name is dictionnaryService !

I am…

I am…ActionService

AttributeServiceAuditService

AuthenticationServiceAuthorityService

AVMService

CategoryService

CheckOutCheckInService

ContentService

CopyService

DictionnaryService

FileFolderService

EditionService

ExporterServiceImporterService

MimeTypeService

MultilangualContentService

NodeService

LockService

RuleService

ScriptService

SearchService

TemplateService

TransactionServiceVersionService

WorkflowService

All right… Could you give us an example ?

The NodeService of course !

NodeService allows to…

Des propriétés

Des métadonnéesCREATE

NodeService allows to…

Des propriétés

Des métadonnéesSET

NodeService allows to…

Des propriétés

Des métadonnéesGET

NodeService allows to…

Des propriétés

Des métadonnéesDELETE

Properties

AssociationsNODES

Aspects

Let’s Practice

Calling Service Registry…

Calling NodeService…

NS

Using NodeService…

NS

Call me King of the Nodes

NS

My skills

CREATE

DELETE GET

SET

NS

On the first day, create a store

Workspace, SpaceStore

Yes, I am THE legendary RootNode!

ServiceRegistry.getNodeService.createStore(protocol,identifier)Java Code

TypeQname sys:store_root

Here you are, Junior!

ServiceRegistry.getNodeService.createNode(parentRef, assocTypeQname, assocQname, nodeTypeQname, properties)

Java Code

Daddy!!!TypeQname cm:foldercm:Name Alfrescocm:title Alfresco

AssocTypeQname cm:containsAssocQName app:company_home

NS

Next, create a node

ServiceRegistry.getNodeService.createNode(parentRef, assocTypeQname, assocQname, nodeTypeQname, properties)

Java Code

NS

Let’s go faster…

The proof in Alfresco!

Java Code

NS

Now, let’s take a closer look into it...

But before, don’t forget…

To identify and report a single node in a store, we

used…

UUID

The concatenation of the store protocol, store name and node UUID creates…

ANodeRef

ServiceRegistry.getNodeService.getStores ()Java Code

NS

So I was saying, let’s take a closer look!!!!!

Store

ServiceRegistry.getNodeService.getRootNode (StoreRef)Java Code

NS

I’m sure…Somebody’s

watching me…

Now, the root node !

RootNode

ServiceRegistry.getNodeService.getChildAssocs (NodeRef)Java Code

NS

Next, Childassociation…

ChildAssocs

ParentRef

ChildRef

ServiceRegistry.getNodeService.getChildAssocs(NodeRef)Java Code

NS

Another childAssociation…

ChildAssocs

0 1 2 3

ParentRef

ChildRef

ServiceRegistry.getNodeService.getParentAssocs(NodeRef)Java Code

NS

And if we look the other way round…

ParentAssocs

ParentRef

ChildRef

ServiceRegistry.getNodeService.getParentAssocs(NodeRef)Java Code

NS

Again… the other way round…

ParentAssocs

And me? I’m not enough interesting

for you ?

ServiceRegistry.getNodeService.getProperties(NodeRef)Java Code

NS

Now, let’s look at this presumptuous node in more details…

Properties

 Finally !! My moment of glory !

ServiceRegistry.getNodeService.getProperty(NodeRef,QName)Java Code

NS

The value of title property…

QName cm:title

ServiceRegistry.getNodeService.getProperty(NodeRef,QName)Java Code

NS

Node Type…

QName cm:type

Have you the right to do this ?

ServiceRegistry.getNodeService.setProperty(NodeRef,QName)Java Code

NS

Now, have some fun! Let’s change!

QName cm:description

What ?????

The proof in Alfresco

ServiceRegistry.getNodeService.removeChildAssociation(ChildAssociationRef)

Java Code

NS

Eh eh… DESTRUCTION!!!

I feel that I will find myself all alone…

ServiceRegistry.getNodeService.addChild(parentRef, childRef, assocTypeQname, qname)

Java Code

NS

And reconstruction…

You are my dad ??

Ok, we are done for today !

Now , it’s up to you to discover the rest of

services!

And go your own way.

A last question please….!

So finally Alfresco is a package of services to manage nodes?

Yes !! It’s as simple as that…If we see it as a bigger picture

Any questions ???

For the next meeting maybe…

To be continued…

What if I want to share the content?

You can use protocols …

So if you want to learn…

…To go fast…

…and to reach your goals …
