在Alfresco内容模型中创建一个方面 [英] Create an aspect in Alfresco Content Model

问题描述

我现在开始使用Alfresco CMS。我需要在我的内容模型中创建一个aspect，它必须包含一些属性：

I am starting currently using Alfresco CMS. I need to create an "aspect" in my content model which must contains a number of properties as:

Aspect: 
    property 1 : String
    property 2 : int
    property 3 : int
    property 4 : long

此外，它还必须包含两个属性，由多个属性组成：

Moreover it must contains two more properties which are composed either of number of properties as:

Format: 
   FormatProperty1: int
   FormatProperty2: int
   FormatProperty3: int

Metadata:
   list1: List<String>
   list2: List<String>
   MetadataProperty 3: boolean

我还没有创建一个简单的内容模型在Alfresco。基于我在关系数据库中的以前的知识，我认为上述结构是表之间的关联。我如何在一个方面或更多方面在Alfresco内容模型中执行？

I have not yet created neither a simple content model nor an aspect in Alfresco. Based on my previous knowledge in Relational Databases I perceive the above structure as association between tables. How can I carry out that in Alfresco content model with an aspect or more?

推荐答案

您应该查看这里。
在Alfresco中创建模型远离数据库。

You should take a look here first. Creating a model in Alfresco is far away from a DB.

它只是一个定义好的XML。您必须先编写XML，然后通过引导来初始化。

it's just an XML well defined. You have to write the XML first, then initialize it through bootstrap.

示例XML模型cmodModel.xml：

Example XML Model cmodModel.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Definition of new Model -->
<model name="custom:custommodel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
    <!-- Optional meta-data about the model -->
    <description>Custom Model</description>
    <author>Whatever</author>
    <version>1.0</version>
    <!-- Imports are required to allow references to definitions in other models -->
    <imports>
        <!-- Import Alfresco Dictionary Definitions -->
        <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d" />
        <!-- Import Alfresco Content Domain Model Definitions -->

        <import uri="http://www.alfresco.org/model/system/1.0" prefix="sys" />
    </imports>
    <!-- Introduction of new namespaces defined by this model -->
    <namespaces>
        <namespace uri="custom.model" prefix="cmod" />
    </namespaces>

                </property>
            </properties>
        </aspect>
</aspects>
</model>

模型上下文命名为cmod-model-context.xml

model context named cmod-model-context.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
    <!-- Registration of new models -->
    <bean id="extension.dictionaryBootstrap" 
        parent="dictionaryModelBootstrap" 
        depends-on="dictionaryBootstrap">
        <property name="models">
            <list>
                <value>alfresco/extension/model/cmodModel.xml</value>
          </list>
        </property>
    </bean>

</beans>
