> 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
