Examples of ITag

com.subgraph.vega.api.model.tags.ITag
A tag is a unique single word identifier that can be applied to a record such as a web transaction or a scan to mark it as significant and to simplify later searching.
org.apache.flex.swf.tags.ITag
The interface for all the SWF tags. Each tag has a type code.
