Richard Ding commented on ATLAS-1955: ------------------------------------- [~davidrad] and [~mandy_chessell] suggested using _PrimitiveDefs_ instead of _attributeTypeDefs_. I think it is a better name for custom data types. > 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 > Assignee: Richard Ding > 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)
