Introducing Grakn Academy. A full online course which teaches you all the basics of Grakn. From Grakn zero to Grakn hero.

Graql

  • Resource renamed to Attribute
  • ResourceType renamed to AttributeType
  • Relation renamed to Relationship
  • RelationType renamed to RelationshipType
  • Types and Schema Concepts are no inserted with define. Data continues to be inserted with insert. For example:
define person sub entity;
insert $s isa person;
  • Rules are now part of the schema. For example defining a rule is now:
define my-rule sub rule when {...} then {...};
  • Match queries now known as get queries must now end with get. For example:
match $x isa person; get; 
match $x has name $xn; ($x, mother: $y); $y has name $yn; get $xn, $yn; 
  • Introduced as syntax for more easily accessing links between entities and attributes. This is to make data provenance easier. For example:
match $x isa person has name "Bob" as $r; get $r; 
  • Optimised queries for getting attributes of entity
  • Optimised queries which involve traversing subs
  • Improved error messages on Graql shell
  • Several reasoning optimisations and bug fixes

I guess you meant insert instead of inset for the type and schema example.

Thank you for the release!
