Term Store, Term Sets and Terms....are good but what if i want to use them in place of list columns (Creation of a complete list for a single column value like Countries name and use this list as a reference as lookup column, in InfoPath column as source...and many more....). How i will get the term store on some places where i can refer a list simply by using a web service or rest service...
How you can utilize the SharePoint API to programmatically work with Taxonomies and create terms and fetch the terms in your term store. This should give you some nice ideas on how to get going!
1. Dll Reference:
Microsoft.SharePoint.Taxonomy
You’ll find this reference here:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.SharePoint.Taxonomy.dll
2. Namespaces:
So, the first thing we would like to do is to learn how we can read the taxonomies we’ve got in our store. To do this, we utilize Microsoft.SharePoint.Taxonomy.

There’s a few good-to-know classes in this namespace that we’re going to work with:
- Microsoft.SharePoint.Taxonomy.TaxonomySession
- Microsoft.SharePoint.Taxonomy.TermStore
- Microsoft.SharePoint.Taxonomy.Group
- Microsoft.SharePoint.Taxonomy.TermSet
- Microsoft.SharePoint.Taxonomy.Term
The above classes are stated in their hierarchically correct order, meaning means that you start out with the TaxonomySession which contains the TermStore, which contains the Groups.. and so on.
Reading the Metadata store (Managed Metadata Service):
Now lets generate the XML tree with it.
protected void Page_Load(object sender, EventArgs e){SPSite thisSite = SPContext .Current.Site;TaxonomySession session = new TaxonomySession (thisSite);TreeNode treeNode = new TreeNode ();
treeNode.Text = "Corporate MetaData" ;
tvMetadataTree.Nodes.Add(treeNode);
foreach (TermStore termStore in session.TermStores)
{var tsNode = new TreeNode (termStore.Name, null , null , "" , null );
treeNode.ChildNodes.Add(tsNode);
//treeNode = tsNode;
foreach (Group group in termStore.Groups)
{var node = new TreeNode (group.Name, null , null , "" , null );
treeNode.ChildNodes.Add(node);
//treeNode = node;
foreach (TermSet termSet in group.TermSets)
{node = new TreeNode (termSet.Name, null , null , "" , null );
treeNode.ChildNodes.Add(node);
treeNode = node;
foreach (Term term in termSet.Terms)
{AddTermSet(term, treeNode);
}}}}}void AddTermSet(Term term, TreeNode treeNode)
{var node = new TreeNode (term.Name, null , null , "" , null );
treeNode.ChildNodes.Add(node);
treeNode = node;
foreach (Term t in term.Terms)
{AddTermSet(t, treeNode);
}}
The end result will be a simple TreeView control filled with the Metadata structure from the store, looking something like this:
