Creating a managed metadata field

Creating managed metadata fields is a bit different than creating fields of other types. Managed metadata fields are required to be linked to a term set before they can be used. The two types of taxonomy fields are TaxonomyField and TaxonomyFieldTypeMulti. The TaxonomyFieldTypeMulti is used for a multi valued managed metadata.

TaxonomyField field = new TaxonomyField(web.Fields, “TaxonomyFieldTypeMulti”, name);

TaxonomySession session = new TaxonomySession(site);

if (session.DefaultKeywordsTermStore != null)

{

// get the default metadata service application
