Tags are methods for end users to find similar data in different sources. The tool needs to do validation to verify Consistency.
An individual can enter a Tag of DataDomain:MaterialMaster and another person could enter DataDomain:Mat'lMaster. These two are the same and should be flagged by the tool.
When many sources are added in QDC, a dedicated team will need to manually do verification to make sure there is consistency. The tool should have built in verification.
