Israel Varea created ATLAS-1955: ----------------------------------- Summary: Validation for Attributes Key: ATLAS-1955 URL: https://issues.apache.org/jira/browse/ATLAS-1955 Project: Atlas Issue Type: New Feature Components: atlas-core Affects Versions: 0.9-incubating Reporter: Israel Varea Fix For: 0.9-incubating
It would be very nice that Atlas model could contain a way to represent attribute validation. A simple example is that we would like to model a Person, with attributes Name, Email and Country. Now we would like to specify that Email has to follow a specific regular expression, so it would be nice if we could set Email -> hasValidation -> EmailRegex, with EmailRegex having: Name: Email Regular Expresion Expression: /[0-9a-z]+@[0-9a-z]+.[0-9a-z]+/ For more complex types of validation, e.g. checking card number validity, it could be added some external validator function/service. Name: Credit Card Number Validator Validator: org.apache.atlas.validators.creditcard or https://host:port/creditCardValidator For validations from a reference table, for example a country name, it could be: Name: Country Name Ref Validator Reference Column: <country_name_column> where <country_name_column> would be an instance of type Hive_Column or HBase_Column. Since this is a kind of Standarization, it could be placed in [Area 5|https://cwiki.apache.org/confluence/display/ATLAS/Area+5+-+Standards]. A similar approach is followed in software [Kylo|https://github.com/Teradata/kylo/tree/master/integrations/spark/spark-validate-cleanse] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
