SharePoint Managed Metadata 使用总结

　　在SharePoint开发中，通常我们会将数据存储在列表，文档库或者直接存到数据库。但涉及到数据的层级结构时，用列表等存储实现并不是一件简单的事情，这时候就可以使用SharePoint的另外一种存储数据的方式：托管元数据。

　　托管元数据为SharePoint提供了统一的术语库，企业用户可以将各种日常使用的术语存放在托管元数据。托管元数据的另外一个重要特点是树型结构，比较典型的应用时企业的组织架构，将企业组织架构按照层级结构存放到托管元数据中，通过遍历元数据树输出企业组织信息。

　本文着重对开发过程中对托管元数据的操作进行总结，如何配置Managed Metadata Service（托管元数据服务）请查看官方文档，本文不做描述。

 认识托管元数据存储结构

在使用Managed Metadata前，我们先看一下数据的存储结构，在Managed Metadata中，结构类型分为Term Store（容器）、Group、Term set和Term。

它们的关系可以用下图表示：

Managed Metadata Service

• Term Store
  • Group
    • Term Set
      • Term

Group节点只能创建Term Set节点，Term Set节点只能创建Term节点，Term节点可以继续创建Term子节点。

这就是Managed Metadata得数据存储结构，接下来看下如何管理元数据。

路径：Site Settings->Term store management

Term store management是SharePoint自带的托管元数据管理页面，打开Term store management

我们可以看到在当前的网站集中，有一个Managed Metadata Service（Term Store），在此节点下有5个子节点。

在虚线上方的是自定义的Group（Portal等），展开Portal Group后，如图：

可以看到在Portal节点下是Department等Term Set节点，再下一层就是Term节点，如在部门（Department）节点下存储各个部门，以及各部门下的子部门。

这是SharePoint server 2010自带的管理界面，这里我们为了说明元数据存储结构简单介绍一下，接下来是我们开发过程中真正使用元数据的方法。

 托管元数据操作

读数据

using (SPSite site = new SPSite(SiteUrl))
  {
      TaxonomySession taxonomySession = new TaxonomySession(site);
      TermStore termStore = taxonomySession.DefaultSiteCollectionTermStore;
      Group group = termStore.Groups[termgroup];
      TermSet termSet = group.TermSets[termSet_Department];
  }

代码解释：

　　TaxonomySession:获取当前网站集下的 TermStore上下文环境

　　TermStore->Group->TermSet:根据层级结构取得最终的termset

　　DefaultSiteCollectionTermStore：默认的TermStore，可以使用taxonomySession.TermStore[""]修改为指定的TermStore

　　获取TermSet后，就可以通过其Terms属性获取此节点下的所有Terms。

修改term数据

在读取termset以后，下一步尝试修改term，加入以下代码：

    Term term= termSet.Terms["IT"];
    term.Name = "MIT";
    termStore.CommitAll();    

代码解释：

　　获取名为“IT”的Term

　　现在将Name修改为MIT

　　提交所有更改

　注意修改元数据需要有相应的权限，同时需要注意的是修改后由于TimerJob的原因，可能会有一些延迟。

 读取父节点、子节点

          if (!term.IsRoot)
              {
                 Term parent = term.Parent;
              }
           TermCollection child_terms = term.Terms;

代码解释：

　　term.IsRoot:判断是否为根节点

　　term.Parent:如果非根节点，则找到上级节点

　　term.Terms:找到此节点下的所有下级节点

复制、合并、移动节点

　　复制：

    Term term= termSet.Terms["MIT"];
    term.Copy(true);
    termStore.CommitAll(); 

Term.Copy方法会将此节点复制一份名称"Copy of MIT"为保存到当前的TermSet中，参数指定为true则复制会包括子节点。同样TermSet也可以复制，不需要指定参数，方法会自动将其中的子节点也复制，子节点是作为原节点的复用(Reuse)节点存在，复用节点可以通过Source属性访问原节点。

　　合并：

    Term term = termSet.Terms["MIT"];
    Term term4Merge=termSet.Terms["HR"];
    term.Merge(term4Merge);
    termStore.CommitAll();

Merge方法只能针对同样是Source Term的2个节点，也就是说之前复制后的复用节点是不能合并的。上述代码会将term合并到term4Merge。

　　移动：

    Term term = termSet.Terms["HR"];
    Term term4Move=termSet.Terms["Account"];
    term.Move(term4Move);
    termStore.CommitAll();

Move方法应该是最常用到的方法。

Term和Term Set都可以移动，Term可以移动到其他在此Term Store的Term节点或Term Set下，Term Set可以移动到此Term Store的Group节点下。

Move方法可以让用户更加*的移动节点，假设有这样一个需求，用户需要维护企业组织架构，如上述事例中：HR部门需要移动到Account部门下。使用Move方法，可以方便的将HR部门的所有其他组织一起移动到Account部门节点下，免去了重复添加的过程。甚至可以在页面中以拖拽的方式实现，为用户呈现更加直观友好的页面。

TaxonomyHiddenList

在SharePoint站点中，有一个隐藏的TaxonomyHiddenList，可以通过/Lists/TaxonomyHiddenList/AllItems.aspx访问。TaxonomyHiddenList的item对应TaxonomyFieldType字段的值，TaxonomyFieldType字段被赋值后，就会对应的在TaxonomyHiddenList产生一条记录，用来记录TaxonomyField的详细信息，所以TaxonomyFieldType字段也是LookUp字段类型。

自定义TaxonomyFieldType字段

在SharePoint界面中新建TaxonomyFieldType字段无其他需要注意的，主要看下在SharePoint项目中新建TaxonomyFieldType字段。

以下是TaxonomyFieldType字段的定义:

  <Field ID="{47539D90-EB9B-45A5-8591-68077530FD92}" Name="Field_TaxonomyDemo" StaticName="Field_TaxonomyDemo" DisplayName="TaxonomyDemo" Required="FALSE" Group="Custom group" Type="TaxonomyFieldType">
        <Customization>
          <ArrayOfProperty>
            <Property>
              <Name>TextField</Name>
              <Value xmlns:q6="http://www.w3.org/2001/XMLSchema" p4:type="q6:string" xmlns:p4="http://www.w3.org/2001/XMLSchema-instance">{78FF1668-CDDB-4645-8BED-FC2179944F5F}</Value>
            </Property>
          </ArrayOfProperty>
        </Customization>
   </Field>
   <Field ID="{78FF1668-CDDB-4645-8BED-FC2179944F5F}" Name="Field_TaxonomyDemoTaxHTField0" Type="Note" DisplayName="TaxonomyDemoTaxHTField0" StaticName="Field_TaxonomyDemoTaxHTField0" ShowInViewForms="FALSE" Required="FALSE" Hidden="TRUE" CanToggleHidden="TRUE"/>

Field_TaxonomyDemo字段这个字段是TaxonomyFieldType类型，需要注意的是在此字段中，需要引用下面的Field_TaxonomyDemoTaxHTField0字段作为其TextField属性字段。

总结

作为数据管理的一种方法，个人认为SharePoint Managed Metadata好处多多，在实际应用中也有很多方便之处。

SharePoint Managed Metadata的总结大概就是这些了，希望对读者有所帮助，有任何疑问请及时与我讨论。
