            QUESTION

            Enforce references to only fields that exist for an inline object definition?
            Asked 2022-Mar-23 at 22:52

            I want to quickly declare an object where the fields are enforced to be of a specific type (CSSProperties in this example, but I want a generic type in the end).

            When I use an indexed type (or Record), TS restricts values of the member field values to the correct type and will throw errors if I mis-define their contents. But it loses knowledge about what fields have been defined, so a reference to an undefined field will not give a compile error and the caller just gets undefined.

            If you want to enforce and type and at the same infer a more specific subtype, then you have to use a generic function.

            QUESTION

            Does an entity in TypeDB (formerly Grakn) need always a unique identifier?
            Asked 2022-Mar-16 at 14:31

            I'm defining a schema for different persons in my graph knowledge base. A person entity is of course unique in its constellation of attributes. However, suppose just theoretically that we would have two people with the same name ("John Doe") and everything else the same, age, birthplace etc. Would TypeDB treat them as the same person if I do not insert a person-id? I'm trying to understand how TypeDB is differentiating the different entities in its data structure. If for example the two people who just be different in one single attribute, would then TypeDB have two different instances of the John Doe?

            You would get two instances of John Doe. It's pretty-easy to verify; each entity in TypeDB has an internal identifier (called an iid). If you open console and execute this insert statement (assuming a compatible schema) twice you'll get back two entities with different iids:

            insert $p isa person, has first_name "John";

            Result:

            Can I use a relation in TypeDB(formerly Grakn) several times?
            Asked 2022-Mar-01 at 09:59

            I'm putting up my TypeDB schema and I have the entity problem which is caused by many different things, e.g. by a certain practice or a certain factor.

            I specified the relation causing like:

            The relationship roles that each entity can play are defined on the entity definitions themselves.

            So, if you wanted both practice and factor entities to play 'causer' you would define:

            Error: 13 INTERNAL: [QRY16] Invalid Query Pattern
            Asked 2021-Jul-07 at 11:02

            I'm using TypeDB 2.2.0 and I'm getting the following error in Workbase with a query that used to work in previous versions. How do I do "not equal" between two concepts? (see query below)

            ...

            ANSWER

            Answered 2021-Jul-06 at 10:17

            You want not { $t2 is $t; };

            $a is $b declares that $a and $b are exactly the same concept, so not { $t2 is $t; }; says that they are not the same concept. Both forms work for comparing variables that could be entities, relations or attributes.

            There are also value comparators that are only used to compare two variables that denote attributes and compare them by value only:

            • $a = $b
            • $a != $b
            • $a > $b
            • $a < $b
            • $a >= $b
            • $a <= $b

            TypeDB & TypeQL has been built using various open-source frameworks throughout its evolution. Today TypeDB & TypeQL is built using RocksDB, ANTLR, SCIP, Bazel, GRPC, and ZeroMQ, and Caffeine. In the past, TypeDB was enabled by various open-source technologies and communities that we are hugely thankful to: Apache Cassandra, Apache Hadoop, Apache Spark, Apache TinkerPop, and JanusGraph. Thank you!.
