Description

The BaseResourceDefinition uses the AttributeDefintion class from typesystem. There are newer more funcitonal versions of this capability in the atlas-intg project. This Jira is changing over the glossary implementation to the newer entity / type classes.

Instread of the instanceProperties and collectionProperties in the BaseResourceDefintions we should use something in this sort of style :
"
AtlasEntityDef deptTypeDef =
AtlasTypeUtil.createClassTypeDef(DEPARTMENT_TYPE, "Department"+_description, ImmutableSet.<String>of(),
AtlasTypeUtil.createRequiredAttrDef("name", "string"),
new AtlasAttributeDef("employees", String.format("array<%s>", "Person"), true,
AtlasAttributeDef.Cardinality.SINGLE, 0, 1, false, false,
Collections.<AtlasStructDef.AtlasConstraintDef>emptyList()));

AtlasEntityDef personTypeDef = AtlasTypeUtil.createClassTypeDef("Person", "Person"+_description, ImmutableSet.<String>of(),
AtlasTypeUtil.createRequiredAttrDef("name", "string"),
AtlasTypeUtil.createOptionalAttrDef("address", "Address"),
AtlasTypeUtil.createOptionalAttrDef("birthday", "date"),
AtlasTypeUtil.createOptionalAttrDef("hasPets", "boolean"),
AtlasTypeUtil.createOptionalAttrDef("numberOfCars", "byte"),
AtlasTypeUtil.createOptionalAttrDef("houseNumber", "short"),
AtlasTypeUtil.createOptionalAttrDef("carMileage", "int"),
AtlasTypeUtil.createOptionalAttrDef("age", "float"),
"

For the parent child relationships with glossary categories and terms we should be able to have the type system manage edge deletion. As part of this, we will need to investigate whether we could get rid of the disconnect and connect methods added in ATLAS-1186
